7 * src/set.c (set_tic_prop): When xtics (e.g.) were unset, then a new
8 command 'set xtics ...' could lose track of the tic properties being set.
11 2009-08-29 Ethan A Merritt <merritt@u.washington.edu>
13 * configure.in: Remove the EXPERIMENTAL flag from the x11 terminal
14 binary polygon option.
16 * share/LaTeX/Makefile.am: Comment out an uninstall command because
17 it breaks the build script.
19 * NEWS PATCHLEVEL configure.in docs/titlepag.tex src/version.c:
20 Update in preparation for release 4.2.6
22 2009-08-28 Ethan A Merritt <merritt@u.washington.edu>
24 * configure.in: Remove the EXPERIMENTAL flag from the wxt terminal
28 * term/tek.trm: Add support for xterm tektronix emulation
30 2009-07-21 Ethan A Merritt <merritt@u.washington.edu>
32 * src/plot2d.c (store2d_point): If the plot uses palette colors taken
33 from the Z coordinate, then also use Z to auto-scale cbrange.
36 2009-07-16 Ethan A Merritt <merritt@u.washington.edu>
38 * src/save.c: The "set view" command was incorrectly saved twice.
41 2009-07-04 Thomas Sefzick <thse@users.sourceforge.net>
43 * graphics.c (plot_boxes): Minimal fix for off-by-one pixel bug in
44 width of boxes with palette or rgb color. Complete fix is in 4.4.
47 2009-07-01 Mojca Miklavec <mojca.miklavec.lists@gmail.com>
49 * term/aquaterm.c: The "size xx,yy" option should have a comma between
50 xx and yy for consistency with other terminals.
52 2009-06-18 Ethan A Merritt <merritt@u.washington.edu>
54 * src/pm3d.c (set_plot_with_palette is_plot_with_colorbox):
55 Fix an accounting error that caused unnecessary loading of a color
56 palette into plots that do not need one.
57 Backport of V4.4 patch from 2009-01-02
59 2009-06-04 Ethan A Merritt <merritt@u.washington.edu>
61 * src/mouse.c: The following test script triggered multiple problems.
62 "set multi; set x2data time; set x2tics; unset multi;"
63 - initialize mouse_x, mouse_y to -1; test before using
64 - initialize mouse values with VERYLARGE (replace magic number 1e38)
65 - xDateTimeFormat: do not attempt to convert VERYLARGE to a date
67 * time.c (ggmtime): Counting back from 1.e38 by one year at a time takes
68 forever. Limit the range of acceptable time values to +/- 10^12 seconds,
69 which gives a range of 33688 years forward or back.
70 * axis.c (gen_tics): Skip calculation of 0-length minor ticks
74 2009-05-30 Thomas Sefzick <thse@users.sourceforge.net>
76 * src/graph3d.c (do_3dplot): Adjust position of 3D plot with

92 * term/PostScript/cp1250.ps: Fix code points for Lcaron, lcaron.
95 2009-05-05 Thomas Sefzick (thse@users.sourceforge.net)
97 * term/pslatex.trm: 'set epslatex ... blacktext' was producing white
98 text for tics labels, axis labels, key labels, but black title text.
101 2009-04-09 Ethan A Merritt <merritt@u.washington.edu>
103 * src/gplt_x11.c: Filled boxes and filled polygons have different
104 behaviour when the fillstyle is FS_DEFAULT, but the x11 driver was
105 not making this distinction. (caused by patch of 2008-06-22).
107 2009-03-29 Ethan A Merritt <merritt@u.washington.edu>
111 2009-03-28 Ethan A Merritt <merritt@u.washington.edu>
113 * src/graphics.c (boundary): Reserve room for user tic labels even if
114 the format for autoticks is "".
116 * src/set.c (load_tics) src/save.c (save_tics): Do not save or restore
117 axis tic labels that were read from a data file.
120 2009-03-26 Ethan A Merritt <merritt@u.washington.edu>
122 * src/graphics.c (boundary): Fix bug that caused the left/right margin
123 offsets to be applied twice, leading to too-wide margins.
126 2009-03-26 Petr Mikulik <mikulik@physics.muni.cz>
128 * src/history.c (write_history_list): Indexing istart from 1 otherwise
129 "history" command (without arguments) does not work.
131 2009-03-24 Ethan A Merritt <merritt@u.washington.edu>
133 * src/datafile.c: Fix breakage if configured --disable-binary-data-file
136 2009-03-24 Petr Mikulik <mikulik@physics.muni.cz>
138 * src/pm3d.c (pm3d_plot): The quadrangles are only prepared but not
139 drawn by this routine in pm3d depthorder mode, thus set_color() should
142 2009-03-23 Ethan A Merritt <merritt@u.washington.edu>
144 * src/win/wgraph.c (Wnd_exec_event): Clean the 2nd parameter sent to
145 gp_exec_event after a keypress. This should fix the problem leading to
146 "protocol error" messages.
148 2009-03-18 Ethan A Merritt <merritt@u.washington.edu>
150 * src/wxterminal/gp_cairo.c (gp_cairo_draw_text): Determine the vertical
151 placement of text based on the average value found when the font was
152 selected, rather than on the specific height of this text fragment.
153 Otherwise successive fragments with different height produce an uneven
154 baseline. Bug #2661664
156 * src/axis.c (make_tics): Trap case where there were insufficient data
157 to determine axis range. E.g. "set view map; set pm3d; splot {0,1};".
159 2009-03-15 Ethan A Merritt <merritt@u.washington.edu>
161 Increment patchlevel, version strings, documentation dates, and NEWS in
162 preparation for release of version 4.2.5
164 2009-03-13 Ethan A Merritt <merritt@u.washington.edu>
166 * demo/datastrings.dem demo/histograms.dem demo/histograms:
167 Switch demos to use the documented syntax "... title columnhead(2)"
168 rather than the deprecated "... title 2"
170 2009-03-05 Ethan A Merritt <merritt@u.washington.edu>
172 * src/graphics.c: Fix assignment of fill patterns to plot boxes and key
173 for columnstacked histograms. Bug #2664732
175 2009-03-04 Ethan A Merritt <merritt@u.washington.edu>
177 * src/graphics.c (find_maxl_keys do_plot): The first entry in a list of
178 labels is a placeholder for style information. Do not reserve space for
179 this entry in the key of a columnstacked histogram plot. Bug #2664723
181 2009-03-02 Ethan A Merritt <merritt@u.washington.edu>
183 * term/hpgl.trm term/tgif.trm term/gd.trm:
184 Fix illegal memory access violations found by valgrind.
186 2009-03-02 Petr Mikulik <mikulik@physics.muni.cz>
188 * term/post.trm (PS_encode_image print_five_operand_image): Fix
189 related to the patch of post.trm from 2009-01-26: images drawn
190 "with rgbimage" must always be drawn as rgb colour images.
191 SF Patch #2613919: postscript outputs colour RGB as palette image
193 2009-02-25 Ethan A Merritt <merritt@u.washington.edu>
195 * term/gd.trm (PNG_text_angle): Force angle to fall in the range
196 [-pi/2 : pi/2]. Reported to avoid problems in some versions of libgd.
198 2009-02-16 Ethan A Merritt <merritt@u.washington.edu>
200 * docs/titlepag.tex docs/gnuplot.doc term/cgm.trm:
201 Remove duplicate keyword entries. Put version number on title page.
203 2009-02-14 Ethan A Merritt <merritt@u.washington.edu>
205 * demo/all.dem demo/heatmaps.dem: Add heat maps to demo set.
207 2009-02-11 Petr Mikulik <mikulik@physics.muni.cz>
209 * config/makefile.mgw: Use $(CC) instead of gcc to compile pgnuplot.
211 2009-02-07 Ethan A Merritt <merritt@u.washington.edu>
213 * term/x11.trm (X11_options): Call term->init() rather than X11_init(),
214 since the options routine is shared by x11 and xlib drivers.
216 2009-02-05 Ethan A Merritt <merritt@u.washington.edu>
218 * src/util.c (type_udv) src/eval.c (add_udv_by_name) src/fit.c
219 src/plot2d.c: Prevent strange behaviour due to uninitialized field
220 udv_type in a udv entry that has been created but not yet defined.
223 * src/graph3d.c (draw_3d_graphbox): Allow Z axis label in 3D plots
226 2009-02-02 Petr Mikulik <mikulik@physics.muni.cz>
228 * src/mouse.c (lookup_key): Use exact match, otherwise F10, F11, or F12
231 2009-01-28 Petr Mikulik <mikulik@physics.muni.cz>
233 * src/breaders.c (edf_filetype_function): Fix for long headers.
235 2009-01-27 Petr Mikulik <mikulik@physics.muni.cz>
237 * src/pm3d.c (pm3d_plot): Fix for "set pm3d depthorder" ignoring
238 "set pm3d interpolate".
240 2009-01-26 Petr Mikulik <mikulik@physics.muni.cz>
242 * term/post.trm (PS_make_header PS_image): Since the beginning of pm3d,
243 the "/Color def" switched between gray and colour map. Choosing "false"
244 for "Color", the gray map was always selected regardless the use of a
245 custom palette. This led to ambiguities for custom colour palettes if
246 they contain grays only. Thus let postscript choose always colour
247 palette for interpolated colours ('set palette defined', 'set palette
248 file') and colour/gray according to "Color" otherwise ('set palette
249 gray', 'set palette rgb').
250 SF Patch #2516634: custom colormap using postscript term
252 2009-01-22 Ethan Merritt <merritt@u.washington.edu>
254 * term/svg.trm: Back-port changes to svg terminal driver from 4.3 CVS.
255 This adds support for dashed lines, additional color modes,
256 more standard xml syntax for attributes, and a work-around for viewers
257 that fail to correctly inherit <text xml:space="preserve">
259 2009-01-21 Ethan Merritt <merritt@u.washington.edu>
261 * src/fit.c (fit_command): Issue a warning if no fittable parameters
265 2009-01-14 Ethan Merritt <merritt@u.washington.edu>
267 * src/util.c: Replace the file util.c with the correct file for this
268 CVS branch. Somehow the copy from the 4.3 branch got incorrectly
271 2009-01-14 Petr Mikulik <mikulik@physics.muni.cz>
273 * src/gplt_x11.c (process_event): Change the status bar of a non-active
274 or persistent window only for almost2d plot.
276 * src/gplt_x11.c (exec_cmd): Add field almost2d to plot_struct and set
277 it according to sent ALMOST2D.
279 * term/x11.trm (X11_text): Send information about ALMOST2D.
281 * src/gadgets.h src/mouse.c: Move definition of macro ALMOST2D to
284 2009-01-13 Petr Mikulik <mikulik@physics.muni.cz>
286 * config/makefile.mgw: Option to run gdlib-config to determine libraries
287 for linking of gd. Fix link where to download hcw.
289 2009-01-07 Ethan Merritt <merritt@u.washington.edu>
291 * src/util3d.c (edge3d_intersect): Fix long-standing bug in which
292 the z coordinate was clipping against xmax rather than zmax.
295 2008-12-27 Allin Cottrell <cottrell@wfu.edu>
297 * util.c (gprintf): Allow '#' format character.
299 2008-12-26 Ethan Merritt <merritt@u.washington.edu>

305 * term/x11.trm src/gplt_x11.c: Added size and position options for X11.
307 2008-12-17 Ethan Merritt <merritt@u.washington.edu>
309 * term/x11.trm (parse_driver): Do not overwrite environmental variable
312 2008-12-14 Ethan Merritt <merritt@u.washington.edu>
314 * src/gadgets.c src/gadgets.h src/graph3d.c src/graph3d.h src/save.c
315 src/show.c src/unset.c docs/gnuplot.doc:
316 More work on "set view equal {xy|xyz}'. It now works well for terminals
317 with isotropic coordinate systems, but unfortunately not for x11 or
320 2008-12-13 Ethan Merritt <merritt@u.washington.edu>
322 * term/emf.trm: Replace assert() statements with int_warn().
323 Fix handling of enhanced text for which the rotation angle is non-zero.

331 src/term_api.h src/term.c (term_initialise):
333 ./configure --with-readline=bsd
334 Allow gnuplot to use the NetBSD editline library as an alternative to
335 gnu readline. This adaptation was originally coded by Bastian Maerkisch
336 and subsequently improved by Axel Thimm and by Tormod Volden.
338 The routine term_init() is renamed to term_initialise() to avoid
339 conflict with an identically named routine in libedit.
341 2008-12-11 Ethan Merritt <merritt@u.washington.edu>
343 * src/fit.c src/show.c src/variable.c term/pdf.trm:
344 Quiet some compiler warnings.
346 2008-12-07 Ethan Merritt <merritt@u.washington.edu>
348 * src/graphics.c (do_key_sample do_rectangle): Fill style EMPTY
349 should be no fill at all, rather than fill with background.
352 2008-12-04 Ethan Merritt <merritt@u.washington.edu>
354 * src/datafile.c: Give an error message if the user requests any
355 unimplemented features documented for 'set datafile binary'.

368 * docs/gnuplot.doc src/gadgets.c src/gadgets.h src/graph3d.c src/save.c
369 src/set.c src/show.c src/unset.c NEWS:
370 The docs say that 'set size ratio' is ignored in 3D; make it so.
371 New option 'set view equal_axes' that forces x and y axes in a 3D plot
372 to use the same scale. This is similar to 'set size square' in 2D.
373 Bug #2004205. Feature request #2006851.
375 * src/set.c (prune_dataticks): Fix typo causing ticlabel list corruption
377 2008-11-19 Ethan Merritt <merritt@u.washington.edu>
379 * term/gd.trm (PNG_options): If no information is available about what
380 default scalable font might be available we currently give up and fall
381 back to a built in non-scalable font. Now we try font "arial" before
382 falling back. Who knows, it might even be available.
384 2008-11-13 Ethan Merritt <merritt@u.washington.edu>
386 * docs/gnuplot.doc docs/gnuplot.texi: Update section on color selection
387 to include "lc variable".
389 2008-11-06 Ethan Merritt <merritt@u.washington.edu>
391 * term/x11.trm (X11_set_font ENHX11_put_text): Initialize enhanced text

395 * src/set.c (set_tics) src/show.c (show_tics) src/save.c (save_set_all)
396 docs/gnuplot.doc: Allow tics to be set front/back without turning on
397 the whole grid. Syntax: set tics {front|back}
399 2008-10-30 Ethan Merritt <merritt@u.washington.edu>
401 * src/axis.c (gen_tics) src/axis.h: Use a more complete test for
402 round-off error when the increment between axis tics is close to the
403 precision of the floating point representation.
406 2008-10-27 Ethan Merritt <merritt@u.washington.edu>
408 * src/misc.c (lp_parse) src/graphics.c (check_for_variable_color):
409 New colorspec: 'lc variable'
410 Read linestyle index from data column, look up corresponding color.
411 (2D plots only; Version 4.2 handling of variable color in 3D is messy).
413 2008-10-12 Ethan Merritt <merritt@u.washington.edu>
415 * src/plot2d.c (eval_plots): Explicitly set default color of first
416 histogram to linestyle/linetype 0.
419 2008-10-10 Petr Mikulik <mikulik@physics.muni.cz>
421 * src/win/pgnuplot.c: Document option "-e".
423 2008-10-10 Shigeharu Takeno <shige@iee.niit.ac.jp>
425 * src/win/wgraph.c (drawgraph): Work around a Windows clipboard bug by
426 using ExtCreatePen() only for linewidth != 1. The clipboard loses the
427 line color if created with ExtCreatePen(), but not CreatePenIndirect().
428 [sfeam] Is the clipboard problem still present for thicker lines?
430 2008-10-08 Shigeharu Takeno <shige@iee.niit.ac.jp>
433 Add a command line option -e to execute specified commands:
434 E.g.: gnuplot file1.in -e "reset" file2.in
436 2008-10-06 Juergen Wieferink <wieferink@freenet.de>
438 * src/set.c (set_palette_defined): Allow string variables and
439 expressions in "set palette defined". SF #2149065
441 2008-10-01 Ethan Merritt <merritt@u.washington.edu>
443 * src/plot2d.c (store_label): Only store color value for each label
444 in a "with labels" plot if "rgb variable" has been requested.
447 2008-09-29 Petr Mikulik <mikulik@physics.muni.cz>
449 * src/color.h: Add field c into structure gpdPoint.

464 src/graphics.c (plot_border) demo/random.dem:
465 Add an axis tic attribute "rangelimited". If set, the border and
466 tics for this axis will be drawn only for the range of the data,
467 rather than for the full range of the axis.

505 characters that must be escaped in postscript enhanced mode.
508 2008-09-03 Ethan Merritt <merritt@u.washington.edu>
510 * src/axis.c (add_tic_user): NULL labels are OK if requested via
511 'set xtics (x1, x2, ...)' as opposed to read from a data file.
513 2008-09-02 Juergen Wieferink <wieferink@freenet.de>
515 * src/eval.c src/gp_time.h src/internal.c (f_strftime f_strptime)
516 src/internal.h demo/stringvar.dem docs/gnuplot.doc:
517 Introduce two new functions 'strftime' and 'strptime', which do
518 essentially the same as the standard C functions with the same names,
519 but use seconds since 2000 instead of struct tm.
520 This has been in 4.3 cvs for 18 months now with no reported problems.
521 (Patchset #1199186 July 2005).
523 2008-08-16 Ethan Merritt <merritt@u.washington.edu>
525 * term/dumb.trm: Accept terminal size in the form used by most other

532 2008-08-09 Ethan Merritt <merritt@u.washington.edu>
534 * src/readline.c (ansi_getc): Teach built-in readline to map
535 CSI-H to ^A and CSI-F to ^E, which offers some hope that the <end> and
536 <home> keys will do something useful.
539 2008-08-06 Benjamin <lindnerb@users.sourceforge.net>
541 * term/post.trm: Fix parsing error for option "palfuncparam".
544 * term/emf.trm: Allow fractional linewidths; do not allow dash pattern
545 length to go to zero.
548 2008-08-06 Ethan Merritt <merritt@u.washington.edu>
550 * term/emf.trm: Provide a separate "dashlength" option.
552 2008-08-05 Ethan Merritt <merritt@u.washington.edu>
554 * src/axis.h src/eval.c: Track min/max range of data on each axis
555 indepently of the current axis range itself. Export to the
556 corresponding variables GPVAL_DATA_{AXIS}_MIN and so on.
557 This is useful all by itself, but also lays the groundwork for
558 implementing "range-frame" borders as per request #2025481.
560 2008-08-01 Ethan Merritt <merritt@u.washington.edu>
562 * src/axis.c (add_tic_user): Ignore NULL labels. This prevents possible
563 segfault if tic labels are requested from a non-existent data column.
566 * src/plot2d.c (eval_plots) src/graphics.c (do_plot):
567 Histograms did not correctly honor 'set style user increment'.
570 * src/plot2d.c (eval_plots): Remove order dependency of newhist options.
572 2008-07-29 Ethan Merritt <merritt@u.washington.edu>
574 * src/wxterminal/wxt_gui.cpp(wxt_set_color):
575 Pay attention to the value of 'set palette maxcolors'.
578 2008-07-25 Ethan Merritt <merritt@u.washington.edu>
580 * src/datafile.c (plot_ticlabel_using): If tic labels will be generated
581 from an expression then force evaluation of all column contents.
582 Otherwise references to column() return uninitialized garbage. Bugfix.
584 2008-07-23 Ethan Merritt <merritt@u.washington.edu>
586 * src/mouse.c src/command.c (pause_command) src/command.h:
587 New variant 'pause mouse close' will pause until the plot window is
588 closed. Unlike existing variants, this does not disable mouse-clicks,
589 hotkeys, or zooming. Add wxt to the list of terminals that need a
590 work-around to avoid losing an input character when the plot window
593 2008-07-22 Ethan A Merritt <merritt@u.washington.edu>
595 * src/mouse.c (event_buttonpress): Zooming uses mouse button 3.
596 Do not disable it just because we are using buttons 1 or 2 for something
599 2008-07-21 Ethan A Merritt <merritt@u.washington.edu>
601 * term/post.trm (PS_vector): Work around a bug in ghostscript/gv.
602 If there is a long string of mixed relative/absolute lines without a
603 stroke command, ghostscript renders it veeeery slowly. We already
604 limit the number of relative moves in a row; this patch adds a "stroke".
607 * src/graphics.c (plot_vectors) src/plot2d.c (get_data):
608 Allow 2D vector plots to draw color from an extra data column.
610 2008-07-18 Ethan A Merritt <merritt@u.washington.edu>
612 * src/graphics.c (check_for_variable_color): Consolidate all the checks
613 for deriving color from a data column into a single subroutine.
615 * src/plot2d.c (eval_plots get_data) docs/gnuplot.doc:
616 Allow palette colors in 2D plots.
618 2008-07-16 Ethan Merritt <merritt@u.washington.edu>
620 * src/graphics.c (do_plot) src/graph3d.c (do_3dplot): Move palette
621 initialization earlier, so that no objects or axes are drawn before the
625 2008-07-15 Christian Hilgers <hilgers@muc.zae-bayern.de>
627 * src/plot2d.c src/graphics.c docs/gnuplot.doc: Make stacked histograms
628 grow upward from positive data and downward from negative data.
629 Also adjust and fix autoscaling of stacked histograms.
630 This is a minor change in auto-layout of stacked histograms.
632 2008-07-15 Timothee Lecomte <timothee.lecomte@ens.fr>
634 * src/wxterminal/wxt_gui.h:
635 * src/wxterminal/wxt_gui.cpp (LoadCursor):
636 * src/wxterminal/bitmaps/xpm/cross.xpm:
637 * src/wxterminal/bitmaps/xpm/icon16x16.xpm:
638 * src/wxterminal/bitmaps/xpm/icon32x32.xpm:
639 * src/wxterminal/bitmaps/xpm/icon64x64.xpm:
640 * src/wxterminal/bitmaps/xpm/notfound.xpm:
641 * src/wxterminal/bitmaps/xpm/right.xpm:
642 * src/wxterminal/bitmaps/xpm/rotate.xpm:
643 * src/wxterminal/bitmaps/xpm/size.xpm:
644 Recent gcc versions are stricter with strings. Define xpm char arrays
645 as const. (Backport from 4.3)
647 2008-06-26 Peter Rosin <pekberg@users.sourceforge.net>
649 * term/ggi.trm: uint32 -> unit32_t
650 Allows to build with current version of libggi (2.2.2).
652 2008-06-26 Ethan Merritt <merritt@u.washington.edu>
654 * src/graphics.c: Check for term->filled_polygon() before trying to
655 call it. (fixes segfault triggered by ggi terminal driver).
657 2008-06-25 Ethan Merritt <merritt@u.washington.edu>
659 * src/graph3d.c: Allow to draw contours associated with a pm3d surface.
661 2008-06-24 Bastian Maerkisch <bmaerkisch@web.de>
663 * src/win/wgraph.c (drawgraph): Don't forget to draw a polyline even
664 if it has only a single segment.
667 2008-06-23 Petr Mikulik <mikulik@physics.muni.cz>
669 * src/color.c (draw_inside_color_smooth_box_postscript): Fix colour of
670 the 2nd box in the colour box for negative palette in postscript
674 2008-06-22 Ethan Merritt <merritt@u.washington.edu>
676 * src/plot2d.c: Plot with vectors did not honor linestyles requested via
677 'set style increment user'.
679 * src/gplt_x11.c: Consolidate the fillstyle code into a single routine
680 that is called both by fillbox and filledpolygon processing. This fixes
681 a bug in which the fillstyle border was not applied to filled curves.
683 2008-06-17 Bastian Maerkisch <bmaerkisch@web.de>
684 * src/win/wgraph.c term/win.trm (WIN_set_color): Preserve setting of
685 dash type and linewidth when a new color is selected.
686 Allow dash types with linewidth > 1.
689 2008-06-07 Ethan Merritt <merritt@u.washington.edu>
691 * src/set.c (set_margin) src/save.c (save_set_all) docs/gnuplot.doc:
692 Add keyword "at" to absolute margin placement commands.
693 The full form is now "set rmargin {at screen} 0.8".
695 2008-06-05 Ethan Merritt <merritt@u.washington.edu>
697 * src/axis.c (gen_tics): Interpret tic labels read from a data file as
698 string constants rather than as formats. Otherwise there are problems
699 with labels containing the "%" character.
701 2008-06-02 Ethan Merritt <merritt@u.washington.edu>
703 * src/hidden3d.c (store_polygon) src/mouse.c (event_motion):
704 Replace a pair of assert() statements with a flag that prevents mouse
705 interaction from further increasing the value of surface_zscale. This
706 means you cannot trigger the error condition the asserts tried to guard
707 against by moving the mouse. You can still trigger it by setting the
708 view to something unreasonable, but the previous patch may handle that.
711 2008-06-02 Daniel Sebald <daniel.sebald@ieee.org>
713 * src/hidden3d.c (sort_polys_by_z in_front coord_to_treecell):
714 Add range-checks to the calculation of quadtree array indices.
715 Bugs #1969415 #1728063
717 2008-05-31 Ethan A Merritt <merritt@u.washington.edu>
719 * src/tables.c src/tables.h src/show.c: 'show colornames'.
721 2008-05-31 Allin Cottrell <cottrell@wfu.edu>
723 * term/metapost.trm (MP_filled_polygon): Limit the number of vertices
726 2008-05-29 Ethan A Merritt <merritt@u.washington.edu>
728 * src/axis.c (make_tics): Don't generate tics for an empty axis range.
730 2008-05-27 Bastian Maerkisch <bmaerkisch@web.de>
732 * src/win/wtext.c (TextInit), src/win/wgraph.c (GraphInit):
733 Increase buffer sizes which contain the path to wgnuplot.ini. Fixes
734 crashes on systems with very long paths of the %APPDATA% directory.
736 2008-05-27 Ethan A Merritt <merritt@u.washington.edu>
738 * src/graphics.c (do_key_sample): Do not draw errorbars on candlestick
741 2008-05-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
743 * term/emf.trm (EMF_options): Option 'size' broke out of parsing
746 2008-05-22 Thomas Sefzick <thse@users.sourceforge.net>
748 * src/bitmap.c (b_vector): If either end of a vector would fall outside
749 the canvas area, don't draw it. This prevents segfaults and memory
750 access problems if the terminal coordinates overflow or go negative.
753 2008-05-21 Ethan A Merritt <merritt@u.washington.edu>
755 * src/specfun.c (inverse_error_func): The piecewise numerical
756 approximation failed to handle the case where x was exactly the join
757 point for the pieces. Include +/- 0.7 in the central piece.
758 Also add one more cycle of Newton-Raphson.
761 2008-05-20 Shigeharu Takeno <shige@iee.niit.ac.jp>
763 * term/emf.trm (EMF_dashtype): Don't ignore linetype LT_AXIS.
765 2008-05-08 Thomas Sefzick <thse@users.sourceforge.net>
767 * src/axis.c (setup_tics): If the user specified an explicit
768 tic interval on a timefmt axis, do not change this by calling
769 quantize_time_tics().
772 2008-05-08 Ethan A Merritt <merritt@u.washington.edu>
774 * term/pdf.trm (ENHPDF_FLUSH ENHPDF_put_text): We correctly issue
775 save/restore requests to PDFlib, but we need to mirror these in the
776 terminal code so that we track what font is currently selected.
778 2008-05-03 Ethan A Merritt <merritt@u.washington.edu>
780 * term/cgm.trm: Clean up terminal code.
781 Use shared routines gp_alloc(), int_expression().
782 Switch to using same set of colors as other terminals (web_color_rgbs).
783 Handle RGB color request by returning closest match to a known color.
784 Don't over-write user colors with each new palette.
785 Decouple dash pattern from line color.
787 * term/fig.trm: Extend point types to match standard sequence for the
788 the first 13 types. Accept option syntax "set term fig ... size xx,yy".
789 Add a table lookup for font names known to fig, so that the terminal
790 accepts for example 'set term fig font "Palatino Italic, 11"'.
792 * src/tables.h src/tables.c (lookup_table_entry): New utility routine
793 for table lookup of a string, as opposed to a token index.
795 2008-04-28 Bastian Maerkisch <bmaerkisch@web.de>
797 * term/win.trm: Remove specific references to Windows 3.1
799 2008-04-27 Ethan A Merritt <merritt@u.washington.edu>
801 * src/datafile.c (df_tokenise df_read_matrix): If missing or bad data is
802 found in a matrix data file, print an int_warn() message, set the value
803 to NaN if it isn't already, and return to the caller normally.
804 This allows one to leave holes in a matrix data file.
806 * src/graphics.c (boundary): The windows and postscript terminals place
807 the xlabel text with the character baseline on the bottom edge of the
808 canvas. This causes any descenders to be clipped. This patch leaves an
809 extra 1/5 line height of empty space at the bottom. This fixes windows
810 and postscript, but introduces a small waste of space on most other
814 2008-04-24 Ethan A Merritt <merritt@u.washington.edu>
816 * term/post.trm (PS_encode_image PS_image): If the palette size is
817 limited by "set palette maxcolors" then we need to rescale [0:maxcolors]
818 to [0:bitwidth] for the packed representation of the image in PostScript
821 2008-04-20 Ethan A Merritt <merritt@u.washington.edu>
823 * src/util.c (int_error): Revert patch of 2008-04-19; it is not needed
826 2008-04-19 Ethan A Merritt <merritt@u.washington.edu>
828 * term/sun.trm: Rename local static variable "canvas" to "SUN_canvas"
829 to avoid conflict with global of the same name.
831 * src/util.c (int_error): We really want to use snprintf(), but if the
832 platform doesn't provide it (SunOS 4.1) what can you do?
834 2008-04-16 Ethan A Merritt <merritt@u.washington.edu>
836 * term/x11.trm: Use a more finely sampled palette to generate colors.
837 It was using only 500 samples; change it to use the default (=5000) in
838 approximate_palette().
841 2008-04-08 Ethan A Merritt <merritt@u.washington.edu>
843 * src/parse.c (parse_primary_expression) src/parse.h:
844 Track highest data column referred to in an expression.
846 * src/datafile.c (plot_option_using): Use info returned by perm_at()
847 to update the highest data column used. This allows us to catch at
848 least the simple case of autotitle columnheader for 'using 1:($3)'.
849 It also allows deletion of ugly code to approximate the same thing
853 2008-04-06 Ethan A Merritt <merritt@u.washington.edu>
855 * term/post.trm (PS_set_font): Avoid segfault if the font name is longer
856 than 32 characters. The {ai grass next openstep} terminals suffer from
857 this same problem, but since they are moribund just let it go.
860 * term/gd.trm: Track ttf font names using dynamically-allocated strings
861 rather than fixed arrays.
864 2008-04-01 Thomas Sefzick <thse@users.sourceforge.net>
866 * src/tables.c src/command.c (undefine_command) src/command.h
867 docs/gnuplot.doc: Introduce a new command 'undefine foo baz [...]'
868 that clears previously defined user variables "foo", "baz", ...
870 2008-04-01 Ethan A Merritt <merritt@u.washington.edu>
872 * src/eval.c (update_gpval_variables) docs/gnuplot.doc: Users can
873 clobber the pre-defined variables pi and NaN. Provide permanent,
874 non-clobberable versions GPVAL_pi and GPVAL_NaN so that they can be
875 restored if necessary.
877 2008-03-27 Petr Mikulik <mikulik@physics.muni.cz>
879 * src/save.c (save_set_all): Fixed saving negative palette.
881 2008-03-21 Ethan A Merritt <merritt@u.washington.edu>
883 * src/set.c (set_format): Remove superfluous c_token++.
886 2008-03-20 Ethan A Merritt <merritt@u.washington.edu>
888 * src/graph3d.h src/plot3d.c docs/gnuplot.doc: Add a per-plot splot
889 keyword "nocontours". This overrides the global "set contour", so
890 that you can contour a single surface from a plot with many.
892 2008-03-13 Carl Troein <troein@users.sourceforge.net>
894 * term/post.trm (PS_filled_polygon): Limit the number of consecutive
895 relative moves in order to avoid accumulated round-off error.
897 2008-03-11 Ethan Merritt <merritt@u.washington.edu>
899 * src/gadgets.c src/gadgets.h src/graph3d.c src/graphics.c src/save.c
900 src/set.c src/show.c src/unset.c src/util3d.c: Add option to specify
901 plot margins as an absolute position on the canvas (screen).
902 set {lrbt}margin screen <frac>
903 Back-port of CVS patches from 2006-10-21 2006-11-04 2008-03-06
905 * src/plot2d.c (get_data store2d_point) src/graphics.c (plot_boxes):
906 Alter processing of "with boxes" to handle specification of a column
907 containing variable color information. Back-port from CVS.
909 2008-03-08 Ethan Merritt <merritt@u.washington.edu>
911 Version 4.2.3 release
912 Any further commits to this tree will be in 4.2.4 if such a version is
915 2008-03-08 Ethan Merritt <merritt@u.washington.edu>
917 * term/x11.trm (X11_filled_polygon):
918 Fix read beyond end of buffer found by valgrind.
920 * src/datafile.c (df_tokenise):
921 Fix uninitialized variable found by valgrind.
923 2008-03-07 Ethan Merritt <merritt@u.washington.edu>
925 * src/util3d.c (draw3d_line_unconditional): Check for user-defined
926 line styles when choosing colors for front/back of hidden surfaces.
927 Bugfix (back-ported from 4.3)
929 * src/color.c (draw_color_smooth) src/graph3d.c (do_3dplot cntr3d_lines)
930 src/misc.c (lp_use_properties): Do not fail to initialize the structure
931 passed to lp_use_properties().
932 Bugfix (back-ported from 4.3)
934 2008-03-07 Ethan A Merritt <merritt@u.washington.edu>
936 * src/datafile.c (df_gets): Revert patch from 2008-03-04 because of
937 problems reported in the development version. Revisit after 4.2.3.
939 2008-03-04 Ethan A Merritt <merritt@u.washington.edu>
941 * src/datafile.c (df_gets): Use readline() for reading inline data from
944 * src/graphics.c (boundary): Be more precise in estimating the vertical
945 space required to accommodate rotated tick labels on x and x2 axes.
948 * PATCHLEVEL configure.in src/version.c: Mark as patchlevel 3
950 * NEWS docs/gnuplot.texi: Update in preparation for 4.2.3
952 * share/Makefile.am: Correct error in generating distribution package.
954 2008-03-03 Ethan A Merritt <merritt@u.washington.edu>
956 * src/color.c (draw_color_smooth_box) src/unset.c (unset_axislabel):
957 Allow user to set colorbar label rotatation if the bar is vertical.
959 * src/datafile(adjust_binary_use_spec): Allow more than one binary
960 file in a single "plot" command.
962 2008-03-02 Ethan A Merritt <merritt@u.washington.edu>
964 * term/cgm.trm (CGM_set_color): Decouple dash type from line color.
965 Code clean-up. Use shared routines int_warn(), gp_alloc().
967 2008-03-01 Ethan A Merritt <merritt@u.washington.edu>
969 * term/cgm.trm (CGM_fillbox CGM_filled_polygon): Move the
970 management of fill styles and pm3d fill from CGM_fillbox() to
971 CGM_filled_polygon(). This is necessary because while boxes
972 and histograms call filled_polygon() via term->fillbox(),
973 the pm3d code calls term->filled_polygon() directly. Bugfix.
975 2008-02-29 Ethan A Merritt <merritt@u.washington.edu>
977 * src/set.c (set_format set_tics set_tic_prop) docs/gnuplot.doc:
978 Allow the tic format to be provided as a string variable.
979 Also introduce a format keyword for "set tics" and "set {axis} tics".
980 "set tics format 'foo'" is equivalent to "set format 'foo'"
981 "set ytics format 'baz'" is equivalent to "set format y 'baz'"
983 2008-02-26 Ethan A Merritt <merritt@u.washington.edu>
985 * src/graphics.c (map_position place_objects) src/graphics.h src/mouse.c
986 src/color.c: Change map_position() to return (int) x,y rather than
987 (unsigned int). Callers are modified accordingly. This avoids implicit
988 casting that breaks clipping calculations on ia64 and PPC.
989 This patchset fixes clipping of labels and rectangles. Bugfix.
991 2008-02-23 Petr Mikulik <mikulik@physics.muni.cz>
993 * src/os2/gclient.c: Use the font palette dialog instead of the standard
994 font selection dialog. Still switcheable via #define STANDARD_FONT_DIALOG.
995 SF #1773922 OS/2 PM-Termial broken font selection by Franz Bakan.
997 * config/makefile.cyg: Added GNUPLOT_PS_DIR and WIN_IPC.
999 * config/makefile.dj2 config/makefile.os2: Added GNUPLOT_PS_DIR.
1001 * config/makefile.mgw: Added WIN_IPC.
1003 * config/config.nt config/makefile.nt: Moved GIF_ANIMATION.
1005 2008-02-22 Ethan A Merritt <merritt@u.washington.edu>
1007 * term/pslatex.trm: Include entry point PS_path in the terminal tables
1008 for epslatex, pslatex, and pstex. This fixes a bug due to the code in
1009 color.c:draw_inside_color_smooth_box_postscript() not being able to sync
1010 with the code in the terminal driver.
1012 2008-02-20 Ethan A Merritt <merritt@u.washington.edu>
1014 * src/graph3d.c (place_arrows3d): Save/restore the clipping area so
1015 that splot doesn't trash the current clipping state. Bugfix.
1017 * src/graphics.c (boundary): Reset the default clipping area to the
1018 plot boundary at the start of every 'plot' command. This should not
1019 be necessary, but it provides protection against a hypothetical instance
1020 of int_error() in the middle of a save/draw/restore sequence.
1022 2008-02-19 Ethan A Merritt <merritt@u.washington.edu>
1024 * src/set.c (set_timestamp): Do not spin on unrecognized option. Bugfix.
1026 2008-02-14 Ethan A Merritt <merritt@u.washington.edu>
1028 * src/util.c (gd_strdup) src/set.c (set_decimalsign): Fix segfault due
1029 to trying to free a string returned by getenv().
1032 2008-02-04 Ethan A Merritt <merritt@u.washington.edu>
1034 * src/term.c (change_term): Allow terminals with similar names to
1035 coexist (svg/svga/svgalib). Back-ported from 4.3.
1037 2008-02-01 Daniel Sebald <daniel.sebald@ieee.org>
1039 * src/datafile.c (df_readbinary): Fix off-by-one error in the implicit
1040 "column 0" of non-matrix binary data files.
1042 2008-01-28 Petr Mikulik <mikulik@physics.muni.cz>
1044 * graph3d.c (map3d_getposition, map3d_position_r): Fix case of y graph
1045 coordinate and splot_map.
1047 2008-01-16 Ethan A Merritt <merritt@u.washington.edu>
1049 * src/graphics.c (plot_image_or_update_axes): Do not clip 3D image data
1050 against Z range if the plot mode is "set view map".
1052 2008-01-13 Ethan A Merritt <merritt@u.washington.edu>
1054 Backport fix for Bug #1850588
1056 * src/datafile.c: Call add_tic_user with a tick type of -1 (a new flag
1057 value) rather than 0 (major tick). This allows to distinguish between
1058 tick labels read from a data file and those from the command line.
1060 * src/axis.c (gen_tics): Treat tick type -1 the same as major ticks.
1062 * src/set.c (prune_dataticks) src/setshow.h: New routine to purge any
1063 axis tick labels left over from 'using xtics(n)' option of previous
1066 * plot2d.c (plotrequest): Call prune_dataticks() before each new plot.
1068 2008-01-10 Ethan A Merritt <merritt@u.washington.edu>
1070 * src/pm3d.c (pm3d_plot): When color information is given in a separate
1071 column, we must not use the interpolated z coordinate as for color.
1074 2008-01-10 Petr Mikulik <mikulik@physics.muni.cz>
1076 * src/command.c (replot_command): Fix for replot with unknown terminal.
1078 2008-01-10 Petr Mikulik <mikulik@physics.muni.cz>
1080 * term/post.trm (PS_encode_image): Fix for maxcolors in "plot with
1083 2008-01-10 Daniel Sebald <daniel.sebald@ieee.org>
1085 * src/hidden3d.c (store_polygon): Discard degenerate polygons.
1088 2008-01-07 Allin Cottrell <cottrell@wfu.edu>
1090 * term/pdf.trm (EMF_setfont): Add support for encodings
1091 iso_8859_1 iso_8859_2 iso_8859_15 cp1250
1093 2008-01-06 Allin Cottrell <cottrell@wfu.edu>
1095 * term/emf.trm (EMF_setfont): Add support for encodings
1096 iso_8859_2 cp1250 koi8r koi8u
1098 2007-12-20 Ethan A Merritt <merritt@u.washington.edu>
1100 * term/x11.trm: Fix 4.3-ism in patch of 2007-12-09.
1102 2007-12-17 Lars Hecking <lhecking@users.sourceforge.net>
1104 * share/Makefile.am: Gnuplot is generated by make and deleted by
1105 'make clean'. Bring variable names in line with xorg.
1107 2007-12-14 Ethan A Merritt <merritt@u.washington.edu>
1109 * configure.in: Increase the chance that ./configure will correctly
1110 find all the pieces of gnu libreadline under OSX 1.4.
1112 2007-12-09 Ethan A Merritt <merritt@u.washington.edu>
1114 * term/x11.trm: New option 'set term x11 linewidth LW'
1116 2007-12-08 Ethan A Merritt <merritt@u.washington.edu>
1118 * src/gplt_x11.c: Command line options -bw and -borderwidth were
1119 being mapped to X Resource "borderwidth". It should be "borderWidth".
1120 Also remove limitation that maximum linewidth is 4 pixels.
1122 * share/Makefile.am: Rename Gnuplot.app-defaults to Gnuplot before
1123 installing it. Bug #1784379
1125 * src/graphics.c (place_rectangles): If the linestyle is LT_DEFAULT,
1126 nevertheless check for an explicit linewidth for this rectangle.
1129 2007-12-08 Petr Mikulik <mikulik@physics.muni.cz>
1131 New options "front" and "back" to "set colorbox" to let the box be
1132 drawn either after or below the image or surface.
1134 * src/gadgets.h src/gadgets.c: New "layer" field in color_box_struct.
1136 * src/graphics.c src/graph3d.c: Draw the colorbox at expected layers.
1138 * src/save.c src/set.c src/show.c src/tables.h src/tables.c
1139 docs/gnuplot.doc: The other necessary changes.
1141 2007-12-01 Thomas Orgis <sobukus@users.sourceforge.net>
1143 * src/gplt_x11.c (process_configure_notify_event): Test for failure of
1144 window resize, and do not loop indefinitely trying to resize. Fixes
1145 infinite loop problem on ion and fluxbox window managers.
1146 Bug #1836959 #1614928
1148 2007-11-25 Johannes Zellner <johannes@zellner.org>
1150 * term/emf.trm: implemented pm3d and point types according to the
1151 suggestion in term/README. (2006-12-07 patch to CVS trunk)
1153 2007-11-25 Ethan A Merritt <merritt@u.washington.edu>
1155 * term/estimate.trm: Never return a zero size estimate for a
1156 non-empty string. Promote fraction characters to size 1.
1158 2007-11-25 Vladimir <qva@users.sourceforge.net>
1160 * term/svg.trm (SVG_init): Correct encoding names to koi8-r, koi8-u.
1163 2007-11-23 Ethan A Merritt <merritt@u.washington.edu>
1165 * term/fig.trm (FIG_boxfill): Update current color before drawing.
1168 2007-11-22 Morten MacFly <mortenmacfly@users.sourceforge.net>
1170 * config/config.nt: #define vsnprintf
1172 2007-11-21 Allin Cottrell <cottrell@wfu.edu>
1174 * term/emf.trm (EMF_filled_polygon): Do not alter original color
1175 when processing filled areas with opacity < 1.0
1177 2007-11-20 Ethan A Merritt <merritt@u.washington.edu>
1179 * term/post.trm (RememberFont): Revert patch of 2007-10-23
1180 Parenthesized font names are not compatible with enhanced text mode,
1181 and anyhow PostScript fontnames should not contain any spaces.
1183 2007-11-16 Ethan A Merritt <merritt@u.washington.edu>
1185 * src/term.c (enhanced_recursion): Do not allow the '}' character in a
1186 font name. Prevents PostScript badness from the following user error:
1187 set label "Foo{/Symbol}Baz".
1190 2007-11-02 Ethan Merritt <merritt@u.washington.edu>
1192 * src/internal.c (f_sprintf) docs/gnuplot.doc:
1193 Remove limitation of 10 args max to internal function sprintf().
1196 2007-10-30 Christian Faulhammer (v-li@users.sourceforge.net)
1198 * docs/doc2texi.el: Gentoo patch to allow for changed handling of
1199 newlines in up-coming version of XEmacs. Needed in order to
1200 regenerate gnuplot.texi on such a system.
1203 2007-10-29 Petr Mikulik <mikulik@physics.muni.cz>
1205 * docs/gnuplot.doc: Document option "pm3d depthorder" within
1208 2007-10-23 Christer Lundberg <ssslub@users.sourceforge.net>
1210 * term/post.trm: A font name containing spaces must be protected by
1211 parentheses in PostScript output.
1213 2007-10-05 Ethan Merritt <merritt@u.washington.edu>
1215 * src/plot2d.c (eval_plots): Load first/second axis information into
1216 the head of the label list for plot mode LABELPOINTS.
1219 2007-10-02 Ethan Merritt <merritt@u.washington.edu>
1221 * src/binary.c src/binary.h src/bf_test.c: Rename the routine vector()
1222 to alloc_vector(). This avoids a conflict with the "vector" keyword on
1223 PowerPC OSX with Altivec compiler options enabled.
1226 2007-10-01 Ethan Merritt <merritt@u.washington.edu>
1228 * src/graphics.c (bound_intersect): Fix a degenerate case in the
1229 intersection test that caused a divide by zero.
1232 2007-09-29 Hanno Hoffstadt <hannoh@users.sourceforge.net>
1234 * term/Postscript/prologue.ps: Add an explicit 'closepath' before
1235 filling a rectangle. This is not required by the language spec, but
1236 works around a bug in Adobe Distiller 7 and Apple's Quartz Preview.
1239 2007-09-28 Hanno Hoffstadt <hannoh@users.sourceforge.net>
1241 * src/graphics.c (do_plot): It is necessary to call
1242 term->previous_palette() at the end of any 2D plot or 3D plot
1243 that used custom rgb colors.
1246 2007-09-23 Ethan Merritt <merritt@u.washington.edu>
1248 * src/axis.c (gen_tics): On log scale plots with very large range,
1249 the minitic interval can overflow integer representation.
1252 * term/gd.trm (PNG_image): gdImageGetClip was introduced in libgd
1253 version 2.0.12. Don't try to use it if version is less than 2.
1256 2007-09-01 Ethan Merritt <merritt@u.washington.edu>
1258 Tag version 4.2.2 using command
1259 cvs tag -c "Release_4_2_2"
1261 Version 4.2.2 released via SourceForge. Any further commits to
1262 this tree will be in 4.2.3 if such a version is ever released.
1264 2007-08-31 Ethan Merritt <merritt@u.washington.edu>
1266 The axis label bug is serious enough to warrant an updated release
1267 IMHO. Obviously the release candidate for 4.2.1 didn't get enough
1270 src/version.c PATCHLEVEL configure.in docs/titlepag.tex
1271 Increment patchlevel to 2
1273 2007-08-28 Ethan Merritt <merritt@u.washington.edu>
1275 * src/graph3d.c (draw_3d_graphbox): Fix bug that caused axis labels
1276 not to be drawn in 'set view map' mode. This was supposed to have been
1277 applied 2007-03-14 but somehow never made it into cvs.
1278 Serious bug in 4.2.1
1280 2007-08-28 Ethan Merritt <merritt@u.washington.edu>
1282 * src/graphics.c (plot_c_bars): Apply border color from
1283 'set style fill' to filled candlesticks.
1285 2007-08-26 Ethan Merritt <merritt@u.washington.edu>
1287 Tag version 4.2.1 using command
1288 cvs tag -c "Release_4_2_1"
1290 Version 4.2.1 released via SourceForge. Any further commits to
1291 this tree will be in 4.2.2 if such a version is ever released.
1293 2007-08-25 Ethan Merritt <merritt@u.washington.edu>
1295 * src/version.c src/syscfg.h src/Makefile.am src/win/pgnuplot.c
1297 Update version and contact info for 4.2.1
1299 2007-08-25 Shigeharu Takeno <shige@iee.niit.ac.jp>
1301 * docs/gnuplot-ja.doc docs/faq-ja.tex docs/README.ja docs/term-ja.diff:
1302 Sync Japanese documentation to current version.
1304 2007-08-25 Ethan Merritt <merritt@u.washington.edu>
1306 * src/datafile.c (df_set_key_title): When a key title is loaded
1307 from a datafile columnheader, apply or don't apply enhanced text
1308 processing based on the setting of "set key {no}enhanced".
1311 2007-08-20 Timothee Lecomte <timothee.lecomte@ens.fr>
1313 * src/wxterminal/gp_cairo.c (gp_cairo_fill_pattern): Do not use
1314 negative coordinates to create hash patterns. This gives corruption
1315 with recent cairo versions (1.4.10 for example). Instead create them
1316 with rotations and scaling.
1317 Also scale the linewidth of the patterns with PATTERN_SIZE instead
1320 2007-08-17 Ethan Merritt <merritt@u.washington.edu>
1322 * docs/gnuplot.doc: Remove extraneous {} from entry for 'set timestamp'.
1324 2007-08-12 Ethan Merritt <merritt@u.washington.edu>
1326 * src/color.c (cbtick_callback)
1327 src/graph3d.c (xtick_callback ytick_callback ztick_callback)
1328 src/graphics.c (xtick2d_callback ytick2d_callback):
1329 The callback routines were testing for TC_DEFAULT in the wrong field
1330 (colorspec.lt instead of colorspec.type).
1333 * demo/electron.dem: Remove the "offset command", which is buggy, and
1334 use a consistent x axis. Still need to fix the bug in offset, however.
1337 2007-08-06 Petr Mikulik <mikulik@physics.muni.cz>
1339 * term/x11.trm (X11_text): Fix conditionally missing {.
1341 2007-08-04 Ethan Merritt <merritt@u.washington.edu>
1343 * Tagged using command
1344 cvs tag -c "Release_4_2_1-pre1"
1346 * PATCHLEVEL src/version.c configure.in:
1347 Increment version to Version 4.2.1
1349 * docs/gnuplot.doc docs/gnuplot.texi: Revert leakage from
1350 cvs branch (4.3) documentation into 4.2 documentation. In
1351 particular, 4.2 does not support transparency or iteration.
1353 * Makefile.am: Remove reference to obsolete README.exp
1355 * missing: Nobody "really needs" makeinfo. Allow installs without it.
1357 2007-08-04 Matthias Habl <mhabl@users.sourceforge.net>
1359 * configure.in: Allow to configure from inside an emacs script.
1362 2007-08-02 Ethan Merritt <merritt@u.washington.edu>
1364 * src/command.c (read_line): Treat line extension consistently
1365 for both interactive and non-interactive input paths. This is
1366 Timothee Lecomte's version of the fix.
1369 2007-07-27 Dietmar Warning <dietmar.warning@arcor.de>
1371 * term/win.c (WIN_enhanced_open): Avoid compiler warning.
1373 2007-07-24 Shigeharu Takeno <shige@iee.niit.ac.jp>
1375 * docs/gnuplot.doc: Fixed misprint in "3 multi-branch".
1377 2007-07-24 Petr Mikulik <mikulik@physics.muni.cz>
1379 * term/win.trm: Document reading of wgnuplot.ini in user's %APPDATA%
1382 2007-07-17 Ethan Merritt <merritt@u.washington.edu>
1384 * src/fit.c (fit_command):
1385 Accept a string variable as the file name for "fit via <viafile>".
1388 2007-06-21 Ethan Merritt <merritt@u.washington.edu>
1390 Fix two special cases where gnuplot auto-increments the line type, but
1391 does not check whether the user has requested user-defined line styles
1392 instead (via "set style increment user").
1394 * src/graph3d.c (do_3dplot cntr3d_lines): If the [default] option
1395 `set clabel` is in effect then contours auto-increment over line types.
1396 Check for prefer_line_styles at this point.
1398 * src/graphics.c (do_plot plot_boxes): Columnstacked histograms auto-
1399 increment over line types. Check for prefer_line_styles at thie point.
1401 2007-06-17 Ethan Merritt <merritt@u.washington.edu>
1403 * src/internal.c (f_sprintf): Remove any remaining escape sequences (%%)
1404 from the tail of the format string after all of the input variables have
1408 2007-06-17 Ethan Merritt <merritt@u.washington.edu>
1410 * src/save.c (save_tics): save [xyz]tics must not follow the "offset"
1411 info with a bare number, because a negative number will be mis-parsed.
1414 2007-06-07 Ethan Merritt <merritt@u.washington.edu>
1416 * src/unset.c (unset_label): Do not treat "unset label <n>" as a fatal
1417 error just because label <n> is not currently defined. Bug #1732706
1419 * term/post.trm (PS_load_fontfile): Add missing %. Bug #1732991
1421 2007-06-06 Petr Mikulik <mikulik@physics.muni.cz>
1423 * docs/gnuplot.doc: Hotkey 'q' does not close the pm terminal.
1425 2007-06-04 Petr Mikulik <mikulik@physics.muni.cz>
1427 * term/djsvga.trm: Unify color sequence comply with other terminals.
1428 Fix DJSVGA_set_font(fontname) for an empty fontname.
1430 * src/plot.c (main): Avoid printing "??Unknow" as the System welcome
1431 message under some versions of DOS (compilation by DJGPP).
1433 * config/config.dj2 config/makefile.dj2: Updated Makefile for djgpp
1434 using a config.h file.
1436 2007-06-03 Petr Mikulik <mikulik@physics.muni.cz>
1438 * src/history.c (write_history_n): Cannot use int_error() when exiting
1441 2007-06-03 Petr Mikulik <mikulik@physics.muni.cz>
1443 * config/config.amg config/config.cyg config/config.mgw: Removed
1446 * config/makefile.cyg config/makefile.mgw: Removed PNG_FOR_GIF and GIF.
1447 Write requirement for gd 2.0 and newer. Enable GIF_ANIMATION and JPEG.
1449 2007-06-01 Ethan Merritt <merritt@u.washington.edu>
1451 * INSTALL: Remove obsolete instructions for unix builds without
1452 ./configure, old png driver.
1454 2007-05-31 Petr Mikulik <mikulik@physics.muni.cz>
1456 * src/command.c (pause_command): On Windows, Gnuplot always bailed to
1457 command line after "pause mouse".
1458 Print the message of "pause <message>" into the gnuplot terminal
1459 unless for "pause -1 <message>" (message box).
1461 2007-05-28 Ethan Merritt <merritt@u.washington.edu>
1463 * src/set.c (set_decimalsign): Follow POSIX standard with regard to
1464 finding the value of LC_NUMERIC from the environment. Use the first
1465 match to LC_ALL, LC_NUMERIC, or LANG.
1468 2007-05-25 Ethan Merritt <merritt@u.washington.edu>
1470 * term/latex.trm: Add an explicit size option; clarify documentation.
1471 set terminal {latex | emtex} {default | {courier|roman} {<fontsize>}}
1472 {size <XX>{unit}, <YY>{unit}}
1473 This brings the latex terminal into line with other terminals in 4.2
1475 2007-05-23 Ethan Merritt <merritt@u.washington.edu>
1477 * term/svg.trm: Give font sizes explicitly in pt units.
1479 * term/svg.trm: Subscript/superscripts position must be done using
1480 relative offsets, not absolute offset. Otherwise it prematurely
1481 terminates the scope of the surrounding "chunk" of text.
1483 * Make a concession to non-compliant svg viewers and clean up the scope
1484 of tspan elements. Many current generation svg viewers do not implement
1485 "em" space units. To coddle these, we back off to approximating
1486 1 em == (1.1 * fontsize)pt
1488 2007-05-22 Petr Mikulik <mikulik@physics.muni.cz>
1490 * src/command.c (pause_command): On Windows, "pause -1" does not work
1491 if it is the 1st command in a script. Bug #1713350.
1493 2007-05-22 Timothee Lecomte <timothee.lecomte@ens.fr>
1495 * src/wxterminal/wxt_gui.cpp (wxt_sigint_restore): properly pass a
1496 pointer to signal().
1498 2007-05-19 Ethan Merritt <merritt@u.washington.edu>
1500 * src/plot2d.c (get_data) src/graphics.c (plot_lines):
1501 Allow 2D plots "with lines lc rgb variable".
1504 2007-05-16 Daniel Sebald <daniel.sebald@ieee.org>
1506 * src/gplt_x11.c (image creation): Adjust image line pad according to
1507 image data width in XCreateImage(). Bug #1716389.
1509 2007-05-14 Timothee Lecomte <timothee.lecomte@ens.fr>
1511 * src/command.c (fgets_ipc): Fix fgets_ipc so that it behaves like
1512 fgets (always NUL-terminate the returned string).
1513 Bugs #1716556 and #1673352
1515 2007-05-09 Ethan Merritt <merritt@u.washington.edu>
1517 * src/color.d (ifilled_quadrangle): Initialize line style before
1518 setting color. Bug #1715480
1520 * src/misc.c (lp_use_properties): Pay attention to the point flag
1521 even if we fall through to a default line type. Bug #1715480
1523 2007-05-07 Ethan Merritt <merritt@u.washington.edu>
1525 * term/aquaterm.trm (AQUA_options): Allow terminal window ID to come
1526 from a variable. Bug #1714070
1528 2007-05-05 Timothee Lecomte <timothee.lecomte@ens.fr>
1530 * src/wxterminal/wxt_gui.cpp (wxtThread::Entry):
1531 Fix the initialization of a sigset_t. The structure is not meant to be
1532 known, functions are provided instead. The previous code was
1533 completely wrong on non GNU systems.
1535 2007-05-04 Daniel Sebald <daniel.sebald@ieee.org>
1537 * term/gd.trm (PNG_image): Fixed an image clipping bug in x dimension.
1539 2007-05-04 Ethan Merritt <merritt@u.washington.edu>
1541 * src/graph3d.c (key_sample_point_pm3d): The sample point in the key
1542 failed to note an explicit "lc rgb 'foo'" in the plot command, leading
1543 to a color mismatch between the plot and the key. Bugfix.
1545 2007-04-25 Ethan Merritt <merritt@u.washington.edu>
1547 * src/graph3d.c (do_3dplot): Correct Z coordinate of xyplane for log
1548 scale on Z. Bug #1703370.
1550 2007-04-24 Ethan Merritt <merritt@u.washington.edu>
1552 * term/x11.trm (X11_text): term_reset() tries to close down all files
1553 and pipes cleanly. But it called on exit, the pipe to gnuplot_x11 may
1554 already be closed. Don't try to write to it. Bug #1706945.
1556 2007-04-17 Ethan Merritt <merritt@u.washington.edu>
1558 * term/post.trm: Change the default to "blacktext" for the TeX-based
1559 terminal variants (pstex pslatex epslatex). This is more in line with
1560 the behaviour in versions 4.0 and earlier. In particular it means that
1561 the default settings do not require you to include the color.sty
1564 2007-04-01 Ethan Merritt <merritt@u.washington.edu>
1566 * src/util.c (gprintf): Accept the ' format specifier, which
1567 asks for digits to be grouped and separated according to the current
1568 locale. We just pass it on to the C library for application.
1571 2007-03-27 Ethan Merritt <merritt@u.washington.edu>
1573 * docs/gnuplot.doc: Cross-reference 'set datafile fortran'.
1575 2007-03-23 Ethan Merritt <merritt@u.washington.edu>
1577 * src/color.h src/graphics.c (plot_image_or_update_axes)
1578 term/pdf.trm (PDF_filled_polygon) src/color.c (filled_quadrangle
1579 filled_polygon_3dcoords filled_polygon_3dcoords_zfixed):
1580 Change gpiPoints to contain signed x,y values. This is what the
1581 explanatory comment always implied ("same as in gd.h"), but it
1582 wasn't true. The change fixes several image and polygon clipping
1583 problems, including segfaults in the pdf driver. It also fixes
1584 broken filledcurves on 64-bit machines.
1587 2007-03-21 Daniel Sebald <daniel.sebald@ieee.org>
1589 * src/graphics.c (boundary): The change of 2007-02-25 overlooked the
1590 2D plots having palettes that also required setup_tics(COLOR_AXIS,).
1593 2007-03-21 Ethan Merritt <merritt@u.washington.edu>
1595 These are mostly trivial patches that went into CVS soon after the
1598 * src/graphics.c (plot_impulses plot_points plot_dots)
1599 src/plot2d.c (get_data store_2dpoint store_label):
1600 Allows a third column of data containing color info to be used in
1601 2D plots (points/dots/impulses/labels),
1603 * term/gd.trm (PNG_image) term/pdf.trm (PDF_image)
1604 term/post.trm (PS_image)
1605 src/wxterminal/gp_cairo.c (gp_cairo_draw_fillbox gp_cairo_draw_image):
1606 Teach gd pdf post and wxt terminals to clip images using the
1607 bounding box info passed in corners[2] and corners[3] via term->image().
1609 * term/pdf.trm (PDF_SetFont): Trap errors from PDF font selection,
1610 making it non-fatal.
1612 * src/axis.c (get_position_default):
1613 Reduce the problem of trailing comma after 2D offset.
1615 * src/graph3d.c (plot3d_impulses): splot with impulses lt rgb variable.
1617 * src/graphics.c (do_key_sample):
1618 If the length of a boxplot sample in the key is set to zero, do not
1619 draw it at all. Without this patch, a spurious vertical line appears
1620 in the key if the fillstyle includes a border.
1622 * term/svg.trm (SVG_PathLimit SVG_MoveForced):
1623 Avoid ridiculously long paths by limiting total path length to 512.
1625 * src/util3d.c (draw3d_line_unconditional): Clip line segment.
1626 Fixes segfault when line segment endpoint went negative in bitmap.c
1629 * src/graph3d.c (do_3dplot draw_3d_graphbox):
1630 Add special-case tests to insure that the plot border is drawn either
1631 back or front (in front of the grid) when splot_map is set.
1634 * term/gd.trm (PNG_vector): Grid lines (linetype 0) were always
1635 treated as alternating black/white/black/white. Change this to
1636 alternating current_color/transparent/current_color/transparent.
1639 * src/set.c (parse_label_options):
1640 Make sure that there is a default point type, so that
1641 'set label <n> point' does in fact draw an acceptable point.
1643 * src/datafile.h src/datafile.c (df_reset_after_error)
1644 src/util.c (int_error):
1645 The routines in datafile.c use local variables to track the context of
1646 expression evaluation; e.g. expressions may only reference data column
1647 values inside a `using` statement. But the state of these context
1648 variables is corrupted if an error exit bails directly to the command
1649 line, thus bypassing the normal execution path. Therefore we provide a
1650 routine df_reset_after_error() to be called from int_error().
1652 * src/eval.c docs/gnuplot.doc:
1653 Allow strcol() and shorthand for stringcolumn()
1655 * src/unset.c (unset_style):
1656 Add missing command "unset style line <n>".
1658 * term/gd.trm (PNG_init):
1659 The color palette indexing of the brush is not necessarily the same as
1660 that of the main image. Set initial color index to something invalid so
1661 that we force an update on first use.
1664 * src/term.c (init_term):
1665 Normally we initialize the default terminal on program entry. However,
1666 if the default is x11 then defer initialization until an actual plot
1667 command. This mitigates problems if gnuplot_x11 cannot be started
1668 normally, and allows the user to select a different driver in the case
1669 that x11 is the default but is broken.
1672 * src/win/winmain.c (appdata_directory):
1673 WinNT can segfault if APPDATA is missing from the environment.
1675 2007-03-03 Ethan Merritt <merritt@u.washington.edu>
1677 * PATCHLEVEL src/version.c configure.in docs/gnuplot.texi:
1678 Tag and package for release of 4.2 patchlevel 0
1680 * docs/titlepage.tex: Update
1682 2007-02-27 Ethan Merritt <merritt@u.washington.edu>
1684 * src/graphics.c: Remove spurious #ifdef that was masking the code to
1685 allow room for subscripts or superscripts when placing the x-axis label.
1688 2007-02-26 Ethan Merritt <merritt@u.washington.edu>
1690 * docs/gnuplot.doc: Add mention of "set multiplot title <page-title>".
1692 * term/metapost.trm: Add missing terminal flag.
1694 2007-02-25 Petr Mikulik <mikulik@physics.muni.cz>
1696 * src/color.c (draw_color_smooth_box) src/plot3d.c (eval_3dplots):
1697 Call setup_tics(COLOR_AXIS, 20) at the same place as setup_tics(...)
1698 for all other axes. Until now it was called much later during color box
1699 drawing where it could change the colour axis min or max by rounding it
1700 to lower/upper tics step.
1702 2007-02-22 sobukus@users.sourceforge.net
1704 * m4/apha.m4: Fix syntax of configuration test for gcc on alpha
1706 2007-02-21 Shigeharu Takeno <shige@iee.niit.ac.jp>
1708 * docs/gnuplot-ja.doc docs/faq-ja.tex: Sync Japanese documentation
1711 2007-02-18 Petr Mikulik <mikulik@physics.muni.cz>
1713 * src/pm3d.c (pm3d_plot): Use the z-averaging also for flushed
1716 2007-02-17 Petr Mikulik <mikulik@physics.muni.cz>
1718 * docs/gnuplot.doc: Updates in dgrid3d and contours sections.
1720 2007-02-13 Ethan Merritt <merritt@u.washington.edu>
1722 * src/graphics.c (boundary): Do not apply log scale range checks to
1723 colorbar and palette unless these really are used in the plot.
1726 * docs/gnuplot.doc docs/gnuplot-ja.doc: Clarify the section on
1727 'set log', and remove an empty entry point for 'set log cb'.
1729 2007-02-11 Petr Mikulik <mikulik@physics.muni.cz>
1731 * src/command.c (pause_command): On Windows, cannot wait for Enter
1732 in "pause -1" in a non-interactive session without the graph window.
1734 2007-02-10 Petr Mikulik <mikulik@physics.muni.cz>
1736 * src/command.c (pause_command): On Windows, wait for Enter in console
1737 instead for a mouse click in a special window if the graph window is
1740 2007-02-09 Ethan Merritt <merritt@u.washington.edu>
1742 * term/README: Fix confusing typo in TERM_TABLE layout description.
1744 2007-02-10 Petr Mikulik <mikulik@physics.muni.cz>
1746 SF #1651350 win terminal: pause mouse key|any does not work
1748 * src/mouse.c (event_keypress): Kill pending Pause dialog.
1750 * src/win/wpause.c (PauseBox): Don't show "OK CANCEL" dialog when
1753 2007-02-09 Daniel Sebald <daniel.sebald@ieee.org>
1755 * term/pdf.trm (PDF_point): Point type 1 was incorrectly drawn as a dot.
1758 2007-02-10 Juergen Wieferink <wieferink@freenet.de>
1760 * src/plot.c (main): Flag 'interactive' not reset to FALSE after running
1761 command "gnuplot - nonExistingScript.gp". On some platforms, gnuplot
1762 cannot 'exit' and goes to an infinite loop after Ctrl-D.
1765 2007-02-09 Petr Mikulik <mikulik@physics.muni.cz>
1767 * docs/gnuplot.doc: Add a dummy label for "3 data style" to avoid bug
1768 in doc2gih (try "help contour").
1770 2007-02-08 Petr Mikulik <mikulik@physics.muni.cz>
1772 * src/plot3d.c (eval_3dplots): Improved message for non-grid data.
1774 2007-01-31 Ethan Merritt <merritt@u.washington.edu>
1776 * term/gd.trm (ENHGD_FLUSH): libgd 2.0.34 will allow explicit request
1777 for Adobe Symbol font encoding. Make use of this to handle transient
1778 use of Symbol font in enhanced text. Does not affect older gd versions.
1780 2007-01-29 Per Persson <persquare@mac.com>
1782 * configure.in: Testing libreadline for remove_history presence
1783 instead of readline to avoid incompatible libedit wrapper.
1785 2007-01-26 Petr Mikulik <mikulik@physics.muni.cz>
1787 * term/post.trm: Typo in docs.
1789 2007-01-24 Ethan Merritt <merritt@u.washington.edu>
1791 * src/hidden3d.c (build_networks): Add checks in the hidden3d code to
1792 cleanly skip empty plots. This fix went into the trunk CVS 2 months
1793 ago, but apparently is needed in 4.2 also (test case provided by a
1796 2007-01-23 Ethan Merritt <merritt@u.washington.edu>
1798 * configure.in: The libreadline checks got mangled. Bad patch?
1799 This fixes the breakage, and adds a warning if gd.h is not found.
1801 * PATCHLEVEL src/version.c configure.in:
1802 Tag and package as release candidate 4.2-rc4
1804 2007-01-22 Ethan Merritt <merritt@u.washington.edu>
1806 * PATCHLEVEL src/version.c configure.in:
1807 Tag and package as release candidate 4.2-rc3
1809 2007-01-22 Petr Mikulik <mikulik@physics.muni.cz>
1811 * configure.in: Let the GNU readline be the default instead of the
1812 built-in readline. Improved messages for --with-readline.
1814 2007-01-20 Petr Mikulik <mikulik@physics.muni.cz>
1816 * plot3d.c (plot3drequest): Deactive splot_map when reading [y1:y2]
1817 argument of splot. Fixes axis reversal of set view map;splot [] [y1:y2].
1819 2007-01-19 Petr Mikulik <mikulik@physics.muni.cz>
1821 * demo/pm3d.dem: Better title for plots with scans forward and
1824 2007-01-14 Ethan Merritt <merritt@u.washington.edu>
1826 * src/gplt_x11.c (pr_encoding) term/x11.trm share/Gnuplot.app-defaults:
1827 Gnuplot_x11 has been using a default encoding *-* for x11 fonts. There
1828 is a bug in xorg-7.1 that causes this to fail. So we now provide an
1829 optional X-resource that can be used to set the default encoding to
1830 something else. E.g.:
1831 echo "gnuplot*encoding: iso8859-15" | xrdb -merge
1833 2007-01-10 Ethan Merritt <merritt@u.washington.edu>
1835 * src/gplt_x11.c (PaletteSetColor): Update current color in
1836 plot->current_rgb when setting color from a Palette. Bugfix.
1838 2007-01-09 Ethan Merritt <merritt@u.washington.edu>
1840 * docs/gnuplot.texi: Sync with current docs
1842 2007-01-06 Ethan Merritt <merritt@u.washington.edu>
1844 * term/gd.trm: Add error return check after calling gdImageCreate. This
1845 was not a useful check in earlier versions of libgd, but 2.0.34 will
1846 introduce serious sanity checking at the time of image creation.
1848 2006-12-31 Ethan Merritt <merritt@u.washington.edu>
1850 * docs/term-ja.diff: Sync with current terminal source files.
1852 2006-12-28 Daniel Sebald <daniel.sebald@ieee.org>
1854 * src/datafile.c (isanumber_pn, isatuple, token2double):
1855 Removed these functions as they repeat behavior of and somewhat
1856 inconsistent with real(const_express()).
1857 (plot_option_array): Use : instead of , for separator between elements.
1858 (token2tuple): Use real(const_express()) to parse image parameters.
1859 This allows variables to be used in image specs.
1860 (plot_option_comma_separated): Changed "comma_separated" to
1861 "multivalued" everywhere. Changed the separator to a colon rather than
1862 a comma since the comma conflicts with the separator between multiple
1863 plots within a plot command. The colon is also more consistent with the
1864 separator used in other commands like "using".
1866 * demo/image.dem: Replaced , with : in appropriate places.
1870 2006-12-24 Ethan Merritt <merritt@u.washington.edu>
1872 * term/svg.trm: Remove unused variable to quiet compiler warnings.
1874 2006-12-23 Ethan Merritt <merritt@u.washington.edu>
1876 * src/graph3d.c (draw_3d_graphbox): Honor 2D setting for bmargin
1877 in 3D plots with "set view map".
1879 * configure.in: I still can't spell "COMPATIBLE"
1881 2006-12-21 Ethan Merritt <merritt@u.washington.edu>
1883 * term/gd.trm (PNG_graphics) docs/gnuplot.doc:
1884 Announce deprecation of "set size" to control output canvas size.
1885 Document the intended difference:
1886 set term ... size XX,YY controls size of canvas
1887 set size XX,YY scales relative to the canvas
1888 Warn that png/gif/jpeg (and pbm pdf) terminals honor old syntax for now,
1889 but will require explicit 'set term size ...' in post-4.2 versions.
1891 2006-12-16 Ethan Merritt <merritt@u.washington.edu>
1893 * src/datafile.c (df_tokenise df_parse_string): Allow for quoted
1894 strings in comma-separated value files.
1897 * src/graph3d.c (draw_3d_graphbox): Honor 2D front/back settings
1898 for axis, grid, and border elements in 3D plots with "set view map".
1900 2006-12-15 Ethan Merritt <merritt@u.washington.edu>
1902 * configure.in: Fix spelling of BACKWARDS_COMPATIBLE
1904 2006-12-10 Daniel Sebald <daniel.sebald@ieee.org>
1906 * src/README src/graphics.c (plot_image_or_update_axes):
1907 Augmented sign tests for determining image pixel orientation with the
1908 terminal scales in the x and y dimensions.
1911 2006-12-09 Ethan Merritt <merritt@u.washington.edu>
1913 * src/plot3d.c (get_3ddata): If the first data file is non-empty but
1914 has no usable data, then auto-scaling fails. Instead of a fatal error,
1915 just print a warning and try to plot subsequent data files.
1918 * demo/borders.dem: Replace deprecated syntax defined(bb) with
1921 * configure.in: Make the selection of backwards-compatibility an
1922 explicit option. We have been enabling it without even asking.
1923 Now you can disable it if you want to.
1924 Defaults to --enable-backwards-compatibiliy
1926 2006-12-08 Ethan Merritt <merritt@u.washington.edu>
1928 * src/set.c (set_tic_prop) src/save.c (save_tics): NO_TICS is
1929 a bitmask value, not an integer constant. All tests for NO_TICS
1930 must be masked through TICS_MASK.
1933 2006-12-07 Timothee Lecomte <timothee.lecomte@ens.fr>
1935 * configure.in: Fix use of --without-kpsexpand
1937 2006-11-24 Ethan Merritt <merritt@u.washington.edu>
1939 * docs/term-ja.diff: Update patch to match 4.2-rc2 driver source.
1941 2006-11-28 Timothee Lecomte <timothee.lecomte@ens.fr>
1943 * configure.in: Fix bug in --{en|dis}able-wxwidgets
1945 * src/wxterminal/wxt_gui.cpp:
1946 * src/wxterminal/wxt_gui.h:
1947 Allow building with wxMac, in addition to wxMSW and wxGTK.
1949 2006-11-24 Ethan Merritt <merritt@u.washington.edu>
1951 * PATCHLEVEL configure.in src/version.c docs/gnuplot.texi:
1952 Update in preparation for second release candidate 4.2-rc2.
1954 * term/svg.trm: Back out the raw/escaped option. It needs more thought.
1956 2006-11-23 Mike Sutton <mws116@usa.com>
1958 * term/gd.trm (PNG_init PNG_vector PNG_point): Fix off-by-one error
1959 in specifying brush definitions that control line width.
1961 2006-11-22 Ethan Merritt <merritt@u.washington.edu>
1963 * term/pdf.trm (PDF_graphics): The multiplier from 'set size' was being
1964 applied twice, so the resulting plot scaled as the square of the size.
1965 Apply it only once, to the plot, not to the canvas.
1967 * term/pbm.trm (PBM_graphics PBM_options): Decouple 'set size' from
1968 'set term pbm size XX,YY'. The latter will always yield an XX,YY image.
1969 Maintain (pre-4.2) behaviour if no explicit terminal size is given.
1971 2006-11-19 Ethan Merritt <merritt@u.washington.edu>
1973 * config/makefile.mgw term/PostScript/prologue.ps PostScript/prologues.h
1974 term/post.h: Update version number 4.1 -> 4.2 in several places.
1976 * term/fig.trm (FIG_set_color): TC_LT was handled incorrectly.
1979 * src/misc.c (lp_use_properties): Remove annoying warning messages.
1981 2006-11-18 Ethan Merritt <merritt@u.washington.edu>
1983 * term/fig.trm (FIG_filled_polygon) term/tgif.trm (TGIF_filled_polygon)
1984 term/pstricks.trm (PSTRICKS_filled_polygon): These terminals were
1985 issuing a spurious warning message if term->filled_polygon() was called
1986 without a color palette having been initialized. It is perfectly fine
1987 to fill a polygon with other types of colorspec.
1989 2006-11-17 Ethan Merritt <merritt@u.washington.edu>
1991 * term/cgm.trm (CGM_set_color): Fix stupid typo in array bounds check.
1993 2006-11-16 Ethan Merritt <merritt@u.washington.edu>
1995 * src/plot2d.c (eval_plots): Giving a title for "newhistogram" is
1996 documented as optional. Do not return an error if it is missing.
1998 * INSTALL: Add mention of patches needed for Ultrix compilation.
2000 2006-11-15 Ethan Merritt <merritt@u.washington.edu>
2002 * graphics.h graphics.c (place_rectangles) graph3d.c:
2003 Add a parameter to place_rectangles that indicates with certainty
2004 whether this is a 2D plot or a 3D plot.
2005 Allow rectangles in splot if they are specified in screen coords.
2006 Also, insure that 'set view map' does not affect 2D plots.
2009 2006-11-12 Ethan Merritt <merritt@u.washington.edu>
2011 * src/save.c (save_set_all): The gpsavediff script strips out lines
2012 from a gnuplot save file if the options they describe have not changed
2013 from the default. We can help this simplification by writing
2014 infrequently used suboptions on a separate line. Also change saved
2015 command 'set key nobox' to match documented syntax.
2017 2006-11-10 Timothee Lecomte <timothee.lecomte@ens.fr>
2021 * src/wxterminal/wxt_gui.cpp:
2022 * src/wxterminal/wxt_gui.h:
2023 * src/wxterminal/wxt_plot.h:
2024 Rework and simplify the event handling from the wxt terminal on
2025 Windows. Remove hooks from the wxt terminal in the Windows files.
2027 * src/plot.c (main):
2029 Introduce a boolean to track the use of "-persist" on the command line.
2030 Remove WXWIDGETS-specific code. Call term_reset() using GP_ATEXIT().
2032 * src/wxterminal/Makefile.am:
2033 * src/wxterminal/wxt_plot.h:
2034 Remove the file wxt_plot.h, now unused.
2036 * src/wxterminal/wxt_gui.cpp (wxt_init, wxt_atexit):
2037 * src/wxterminal/wxt_gui.h:
2038 Use GP_ATEXIT() to register wxt_atexit().
2039 Rework "persist" behaviour on Windows.
2042 * wxt_gui.cpp (wxt_atexit):
2044 Use fork() to make the "persist" behaviour satisfying on UNIX.
2046 2006-11-07 Timothee Lecomte <timothee.lecomte@ens.fr>
2048 * src/wxterminal/wxt_gui.cpp (wxtPanel::DrawToDC): Draw the zoom
2049 coordinates with the same font as the plot.
2051 2006-11-04 Ethan Merritt <merritt@u.washington.edu>
2053 * term/x11.trm (parse_driver): If this routine fails on first entry, we
2054 must not call int_error() because the longjump has not been set up yet.
2055 I.e. "setenv GNUPLOT_DRIVER_DIR illegal; setenv GNUTERM x11; gnuplot"
2056 would segfault on entry. Just a print warning and hope the user notices.
2058 2006-11-03 Ethan Merritt <merritt@u.washington.edu>
2060 * src/datafile.c (df_readline): If the datafile we are supposedly
2061 reading from was never opened, simply return DF_EOF. This relieves the
2062 caller from having to check this separately before calling df_readline.
2064 * src/datafile.c (df_open); If the datafile cannot be opened, set
2065 df_eof and return DF_EOF. FIXME: Having both methods is stupid; we
2066 should just get rid of df_eof and use the return value.
2068 * src/graph3d.c (do_3dplot draw_3d_graphbox) src/graphics.c (do_plot):
2069 * src/plot3d.c (eval_3dplots):
2070 Do a better job of skipping over plots marked NODATA. In particular do
2071 not try to scan their data for scaling or plot limits, and do not place
2072 an entry in the key box.
2076 2006-11-03 Ethan Merritt <merritt@u.washington.edu>
2078 * src/datafile.c (df_readbinary): Fix error in logic of 2D and 3D
2079 rotation matrix initialization.
2081 2006-11-01 Ethan Merritt <merritt@u.washington.edu>
2083 * docs/gnuplot.doc: Add an entry key for "help file", because otherwise
2084 this takes you to a section on avs binary format (confusing).
2086 2006-10-28 Ethan Merritt <merritt@u.washington.edu>
2088 * src/show.c (show_ticdef) src/save.c (save_tics): Sace/show textcolor
2089 of tic labels correctly for cases other than a pure linetype (TC_LT).
2092 2006-10-22 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2094 * src/graphics.c (plot_image_or_update_axes): Operator | is
2095 forbidden on real C99 booleans. Use || instead.
2097 * src/datafile.c (df_readbinary): Operator | is forbidden on real
2098 C99 booleans. Use || instead.
2100 * src/axis.c (setup_tics): Operator & is forbidden on real C99
2101 booleans. Use && instead.
2103 * config/makefile.oww (WCFLAGS): Add -za99 to enable _Bool type in
2104 recent versions of OpenWatcom.
2105 (default): Mark .SYMBOLIC for wmake.
2106 (texticon.ico): Avoid endless rebuild by copying the generation
2109 2006-10-21 Ethan Merritt <merritt@u.washington.edu>
2111 * src/datafile.c (df_open): Fix bug limiting the options for reading a
2112 plot key label from the data file; now allow title subcommand:
2113 plot foo using 1:(column(N)) title column(N)
2115 * src/plot2d.c (get_data): Add #ifdef EAM_HISTOGRAMS to a section that
2116 prevented configuration with --disable-histograms
2118 2006-10-21 Timothee Lecomte <timothee.lecomte@ens.fr>
2120 * configure.in: Rework the summary displayed at the end of the
2121 'configure' script, so that it is more complete, useful, consistent and
2124 2006-10-20 Bernhard Simon
2126 * src/color.c (make_palette): Add missing stderr parameter in
2127 FPRINTF debugging statements.
2129 2006-10-17 Ethan Merritt <merritt@u.washington.edu>
2131 * term/svg.trm: option to control treatment of non-ascii characters
2132 "set term svg raw" - pass them through unaltered
2133 "set term svg escaped" - replace byte-by-byte with &#xNN;
2135 * configure.in: Print a warning if snprintf() is not found during auto-
2136 configuration. Recommend that the user provide snprintf() via an
2139 2006-10-15 Ethan Merritt <merritt@u.washington.edu>
2141 * term/gd.trm: Switch to Unicode-compatible representation of octal
2142 characters given as \xxx in a single-quoted test string.
2145 2006-10-14 Ethan Merritt <merritt@u.washington.edu>
2147 * term/svg.trm (SVG_options): Do not reset terminal options to default
2148 values if invoked from `set termoption` rather than `set terminal`.
2151 2006-10-13 Ethan Merritt <merritt@u.washington.edu>
2153 * demo/rgb_variable.dem: Some platforms do not allow you to read a
2154 hexadecimal constant via strtod(). This prevents reading RGB colors as
2155 hexadecimal constants. Add a test for this, and print a warning.
2158 * term/gplt_x11.c: Place #ifdef HAVE_STRDUP protection around a code
2159 section that uses it to send signals to the KDE konsole.
2160 Older systems may not provide strdup(), but they also don't run KDE.
2161 Even if they did, the code in question is hardly a required feature.
2162 Fixes compile problem on Ultrix.
2164 2006-10-12 Ethan Merritt <merritt@u.washington.edu>
2166 * term/svg.trm: Replace -rc1 svg driver with the version from cvs
2167 12 Oct 2006. This changes the handling of escaped characters and
2168 characters given as octal constants. Bug #1575007
2170 2006-10-12 Daniel Sebald <daniel.sebald@ieee.org>
2172 * docs/gnuplot.doc: Small corrections.
2174 * term/post.trm (PS_encode_image): Added gamma correction for images
2175 using a PostScript transfer function. SF Patch [1575425].
2177 2006-10-11 Petr Mikulik <mikulik@physics.muni.cz>
2179 * src/command.c (test_palette_subcommand): Fixed order of set tics
2182 2006-10-10 Ethan A Merritt <merritt@u.washington.edu>
2184 * m4/alpha.m4: Have the new macro use __alpha as the basis for the
2185 test. Checked on Digital Unix 4.0D and Tru64 V5.1
2187 2006-10-10 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
2189 * m4/alpha.m4: New macro GP_ALPHA. Try to auto-detect if
2190 compilater targets DEC Alpha/AXP CPU. If so, add -mieee or -ieee
2191 flag to CFLAGS to avoid FPU weirdness.
2193 * configure.in (GP_ALPHA): Call new macro.
2195 2006-10-08 Petr Mikulik <mikulik@physics.muni.cz>
2197 * NEWS README.1ST src/version.c: Updates.
2199 2006-10-08 Daniel Sebald <daniel.sebald@ieee.org>
2201 * demo/borders.dem: Place all 16 plots on one multiplot.
2203 * demo/all.dem: Put borders.dem inside all.dem.
2205 2006-10-08 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2207 * docs/gnuplot.doc: Fix gotcha in list of alignment
2208 options in 'at <position>' case.
2210 2006-10-05 Ethan A Merritt <merritt@u.washington.edu>
2212 * src/term.c (change_term): For backward compatibility, allow
2213 "set term X" as shorthand for "set term x11".
2215 2006-10-04 Ethan A Merritt <merritt@u.washington.edu>
2217 * tutorial/eg7.plt: Make sure no local encoding is in effect, since
2218 the corresponding TeX package is probably not going to be loaded.
2220 * term/post.trm (PS_vector): Fix breakage introduced by Bugfix #1542050.
2221 The path length must not be set to 0 without issuing a stroke command,
2222 otherwise the current path may never be flushed at all.
2224 2006-10-03 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
2226 * src/graph3d.c (place_arrows3d): Clip arrows even in 3D. Patch
2227 from Harald Harders (SF #1569232).
2229 2006-10-02 Ethan A Merritt <merritt@u.washington.edu>
2231 * share/LaTeX/Makefile.am: If ./configure has determined that TeX is
2232 not installed on this machine, do not try to install gnuplot.cfg
2233 in the TeX directory tree.
2236 2006-10-02 Daniel Sebald <daniel.sebald@ieee.org>
2238 * docs/gnuplot.doc: Changed documentation for image to reflect fact
2239 that uniform sampling is assumed. Fix other typos.
2241 2006-10-01 Ethan A Merritt <merritt@u.washington.edu>
2243 * docs/gnuplot.texi docs/doc2texi.el docs/gnuplot.doc:
2244 Update version number to 4.2 and date to 2006
2246 2006-10-01 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
2248 * PATCHLEVEL: Mark for first release candidate. 4.2-rc1
2250 * VERSION: Bump to version 4.2.
2252 2006-10-01 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2254 * configure.in (AC_INIT, AM_INIT_AUTOMAKE, AC_CONFIG_SRCDIR):
2255 Changed to allow automake version to be checked. Avoid annoyingly
2256 frequent problems from CVS users who just have too ancient
2257 automakes, but only detect that by showing us obscure error
2258 messages. Required automake may have to be increased still.
2260 2006-09-28 Timothee Lecomte <timothee.lecomte@ens.fr>
2262 * src/wxterminal/wxt_plot.h: Fix compilation on Windows, where syscfg.h
2263 has to be included for TBOOLEAN to be defined in wtext.c
2265 2006-09-26 Juergen Wieferink <wieferink@freenet.de>
2267 * src/graphics.c (plot_betweencurves): If the input file contains a
2268 blank line, terminate current filled area and start a new one.
2269 Unfortunately it is not currently possible to distinguish between a
2270 blank line and an invalid/missing coordinate.
2272 * src/plot2d.c (get_data): Add comments to document the problem of
2273 distinguishing a blank line from an invalid data point. (EAM)
2277 2006-09-24 Shigeharu Takeno <shige@iee.niit.ac.jp>
2279 * docs/gnuplot-ja.doc docs/faq-ja.tex: Sync Japanese documentation,
2282 2006-09-23 Ethan A Merritt <merritt@u.washington.edu>
2284 * src/pm3d.c (set_plot_with_palette): It used to be that all plots
2285 needing a colorbox had pm3d_color.type == TC_DEFAULT. This is no
2286 longer true, so add a more specific check on whether a colorbox is
2289 2006-09-23 Timothee Lecomte <timothee.lecomte@ens.fr>
2291 * src/wxterminal/wxt_gui.cpp (wxtPanel::OnSize): Clean floating-point
2292 comparison nonsense.
2294 2006-09-22 Juergen Wieferink <wieferink@freenet.de>
2296 * term/post.trm (PS_vector): To avoid accummulated error in a long
2297 series of relative moves or draws, we were issuing a "stroke" command
2298 periodically to force an update of the absolute position. This has the
2299 bad side affect of resetting the current dot/dash pattern. Fix this so
2300 that instead of using "stroke", we simply force an absolute vector
2301 before continuing. This avoids accummulated error but does not reset
2302 the dot/dash pattern.
2305 2006-09-21 Timothee Lecomte <timothee.lecomte@ens.fr>
2307 * configure.in: Bump required version of wxWidgets to 2.5.3 for the
2310 * src/wxterminal/wxt_gui.cpp (DrawToDC): Fix double cast warnings.
2311 Fix a lazy constructor that seems not to be accepted on all setups.
2313 2006-09-19 Ethan A Merritt <merritt@u.washington.edu>
2315 * src/show.c (disp_value): Force clean printout of "NaN" on save,
2316 print, or show commands. Without this, the value is printed as
2317 "nan.0", which is not parsable by set or load commands. Bugfix
2320 2006-09-16 Timothee Lecomte <timothee.lecomte@ens.fr>
2322 * configure.in: Rework the checks for cairo and pango so that the error
2323 messages are more helpful, mostly by copying the defaults pkg-config
2324 messages and making them non-fatal.
2325 Revert the minimum version of pango to 1.10.0 but refuse to compile the
2326 wxWidgets terminal with pango 1.10.2.
2328 2006-09-16 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2330 * docs/gnuplot.doc (set format): Make documentation for missing
2331 <axes> argument match actual behaviour.
2333 2006-09-15 Timothee Lecomte <timothee.lecomte@ens.fr>
2335 * src/wxterminal/wxt_gui.cpp (DrawToDC): Fill in gray the empty space
2336 that has been let by a change in the aspect ratio of the window.
2338 * trm/wxt.trm (TERM_HELP): Try to document the window resize behaviour
2341 2006-09-14 Timothee Lecomte <timothee.lecomte@ens.fr>
2343 * configure.in: Bump the required version of pango to 1.10.3 to fix a
2344 bug in earlier versions about scaling matrix not being applied properly
2347 2006-09-12 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2349 * docs/gnuplot.doc (format specifiers): Fix typo in one example.
2351 2006-09-11 Timothee Lecomte <timothee.lecomte@ens.fr>
2353 * src/wxterminal/wxt_gui.cpp (wxtConfigDialog::OnButton):
2354 * src/wxterminal/wxt_gui.h (wxt_settings_queue, wxt_settings_apply):
2355 Queue the modified rendering settings instead of applying them right
2356 away, so that the plot is not messed up during a window resize.
2358 2006-09-10 Timothee Lecomte <timothee.lecomte@ens.fr>
2360 * src/wxterminal/gp_cairo.c (gp_cairo_draw_text): Fix the use of the
2361 Symbol font in non-enhanced mode, a peace of code was not pasted
2364 * src/wxterminal/wxt_gui.cpp (wxt_set_font): Fix the use of a
2365 non-initialized integer as the fontsize.
2367 2006-09-10 Shigeharu Takeno <shige@iee.niit.ac.jp>
2369 * docs/gnuplot-ja.doc: Sync Japanese documentation to recent changes in
2370 English files. SF Patch [1519215], rev.1.385.
2372 2006-09-01 Juergen Wieferink <wieferink@freenet.de>
2374 * src/command.c (string_expand): Fix segfault if a truly enormous
2375 string is to be used as an input line.
2377 2006-09-01 Petr Mikulik <mikulik@physics.muni.cz>
2379 * docs/gnuplot.doc: Edits of the "What is new in gnuplot 4.2".
2381 * docs/gnuplot.doc term/x11.trm: Comments on 'raise' does not raise.
2383 2006-08-30 Harald Harders <h.harders@tu-bs.de>
2385 * src/graphics.c (place_arrows): Allow for terminal-specific clipping,
2386 exactly as done elsewhere in the code.
2388 2006-08-30 Ethan A Merritt <merritt@u.washington.edu>
2390 * src/graphics.c (do_plot): The border attribute of fill style was
2391 ignored by filledcurves. Change this to match all other places where
2392 fillstyle is honored.
2394 2006-08-28 Lars Hecking <lhecking@users.sourceforge.net>
2396 * prepare: Allow importing auto* tools from the environment.
2398 2006-08-26 Ethan A Merritt <merritt@u.washington.edu>
2400 Fix program errors revealed by issuing the command sequence
2401 set termoption font 'face,size'; show term
2402 set termoption font 'face'; show term
2403 to all terminal types.
2405 * term/gd.trm term/svg.trm term/tgif.trm: Accept comma-separated font
2406 face, size. Reset to default font size if no size information is given.
2408 * term/tkcanvas.trm: Fix infinite loop if unrecognized terminal option.
2410 2006-08-24 Ethan A Merritt <merritt@u.washington.edu>
2412 * src/plot3d.c (get_3ddata): Increment the current point even if its
2413 value is undefined. This allows grid spacing to be maintained, and
2414 correctly handles `splot ... using ($1):($2):($3)`.
2416 FIXME: This is only a partial solution. Deeper problems exist in the
2417 handling of missing/NaN/junk data values during input. In particular,
2418 gridding is still corrupted in the case of `splot ... using 1:2:3`.
2420 2006-08-23 Ethan A Merritt <merritt@u.washington.edu>
2422 * src/color.c (cbtick_callback): Add handling of text properties
2423 associated with colorbox tic labels, making them like the other axis
2427 2006-08-21 Shigeharu Takeno <shige@iee.niit.ac.jp>
2429 * docs/gnuplot-ja.doc
2430 Sync Japanese documentation to recent changes in English files.
2431 (rev.1.383) 15Aug2006
2433 2006-08-21 Ethan A Merritt <merritt@u.washington.edu>
2435 * src/save.c (save_variables__sub): Do not save NaN to output file,
2436 since it does not print correctly.
2438 * src/eval.c (update_gpval_variables): Make it explicit which variables
2439 are updated from which context.
2441 * src/plot.c (main) src/util.c (int_error): Call update_gpval_variables
2442 on program entry and on int_error.
2444 Bug #1540398 (last release-critical tracker item)
2446 2006-08-19 James R. Van Zandt <jrvz@comcast.net>
2448 * term/cgm.trm: update email address
2450 2006-08-19 Ethan A Merritt <merritt@u.washington.edu>
2452 * src/graphics.c: One half of the definition of clip_fill was
2453 inadvertently omitted from the patch of 2006-06-04. This fix allows the
2454 improved clipping to apply to all filled curves, whereas without it the
2455 new clipping code only checked for "closed" filled curves.
2457 2006-08-16 Ethan A Merritt <merritt@u.washington.edu>
2459 * src/gadgets.h: Initialize default histogram title structure to use
2460 character units for the title offset. Fixes spurious error if the
2461 y axis is log scale.
2463 2006-08-14 Ethan A Merritt <merritt@u.washington.edu>
2465 * src/graphics.c (do_key_sample): Check for terminal support of
2466 term->filled_polygon before using it to draw a key sample. Fixes
2467 segfault in epson driver (and probably others) if a filled area
2468 is assigned an RGB color.
2471 * src/eval.c (update_gpval_variables): Test for term==NULL, and if so
2472 return without doing anything. This prevents a segfault. However, why
2473 does the program not trigger a similar segfault elsewhere?
2476 2006-08-13 Ethan A Merritt <merritt@u.washington.edu>
2478 * docs/gnuplot.doc: Clarify the argument required by exists(), and
2479 provide an example of passing it a string variable containing the
2480 name of another udv (possibly useful in conjunction with macros).
2482 2006-08-13 Petr Mikulik <mikulik@physics.muni.cz>
2484 * docs/doc2tex.c (puttex): Don't split index words at - or _; replace
2487 2006-08-11 Ethan A Merritt <merritt@u.washington.edu>
2489 * term/PostScript/prologue.ps: Remove comment with my name in it.
2490 Further tweak to the PatternBgnd macro.
2492 2006-08-12 Petr Mikulik <mikulik@physics.muni.cz>
2494 * term/PostScript/cp437.ps term/PostScript/cp850.ps
2495 term/PostScript/koi8r.ps: Remove superfluous C comment characters.
2497 * term/PostScript/cp852.ps: Remove my info.
2499 2006-08-11 Timothee Lecomte <timothee.lecomte@ens.fr>
2501 * term/post.trm: Fix preprocessor logic for !defined(GNUPLOT_PS_DIR).
2503 2006-08-11 Petr Mikulik <mikulik@physics.muni.cz>
2505 * term/PostScript/prologue.ps: Replace multiple spaces by a tabulator.
2507 * docs/doc2tex.c (puttex): Remove superfluous spaces around \index{x}.
2509 2006-08-11 Bastian Maerkisch <bmaerkisch@web.de>
2511 * config/makefile.nt: Define GNUPLOT_PS_DIR to use external PostScript
2514 2006-08-11 Petr Mikulik <mikulik@physics.muni.cz>
2516 * docs/gnuplot.doc: Some comments in the help for bind and mouse
2519 2006-08-10 Shigeharu Takeno <shige@iee.niit.ac.jp>
2521 * docs/gnuplot-ja.doc
2522 Sync Japanese documentation to recent changes in English files.
2523 (rev.1.381) 08Aug2006
2525 2006-08-09 Ethan A Merritt <merritt@u.washington.edu>
2527 * term/post.trm term/PostScript/prologue.ps: Move the pattern-fill
2528 background initialization out of the terminal driver and into the
2529 prologue script, with a user-toggle at the top of the file. Allows
2530 pseudo-transparency, and complete redefinition of the pattern styles
2531 without rebuilding gnuplot.
2533 2006-08-09 Timothee Lecomte <timothee.lecomte@ens.fr>
2535 * docs/Makefile.in: Revert change from 2006-07-18 (define
2536 GNUPLOT_PS_DIR), now useless as the PostScript prologue help no longer
2539 2006-08-09 Bastian Maerkisch <bmaerkisch@web.de>
2541 SF Patch [1505261] wgnuplot: open file-open-dialog in current dir
2543 * src/win/wmenu.c (SendMacro): Windows XP uses a strange initial
2544 directory for the file open dialog. This patch forces the dialog to
2545 always open in the current directory. So now, if you change the
2546 directory via 'cd', the file open dialog opens where expected.
2548 2006-08-08 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2550 * src/show.c (show_version): Fix C99-ism by reintroducing
2551 a pair of braces that had been removed.
2553 2006-08-07 Timothee Lecomte <timothee.lecomte@ens.fr>
2555 * src/wxterminal/wxt_gui.cpp (wxtPanel::wxt_cairo_create_bitmap):
2556 Use a reference instead of a pointer to avoid misusing an undocumented
2557 constructor that will be removed in wxWidgets >= 2.7.0.
2559 2006-08-07 Ethan A Merritt <merritt@u.washington.edu>
2561 * demo/all.dem: Add rectangle.dem to the standard test set.
2563 * demo/image.dem demo/macros.dem demo/rainbow.dem demo/rectangle.dem:
2564 Now that we have the configuration options in GPVAL_COMPILE_OPTIONS we
2565 can use this to test for the presence of optional features needed for
2566 any particular demo. These particular demos require configuration
2567 options that are marked EXPERIMENTAL in version 4.2, so we test for
2568 the presence of the feature and if it is missing then we print a
2569 warning message and skip the rest of the demo. This allows "make check"
2570 to succeed even if the EXPERIMENTAL features are configured out.
2572 2006-08-06 Timothee Lecomte <timothee.lecomte@ens.fr>
2574 * docs/gnuplot.doc: Document GNUPLOT_PS_DIR in the list of environment
2577 * INSTALL: Likewise.
2578 Synchronize the output of `./configure --help'.
2579 Document the requirements of the wxWidgets terminal.
2581 * configure.in: Remove detection of libpng, useless since the
2582 standalone png driver has been removed.
2584 * src/Makefile.am (AM_CPPFLAGS); Remove PREFIX and VERSION_MAJOR, those
2585 were used by the wxWidgets terminal but are not anymore.
2587 2006-08-05 Ethan A Merritt <merritt@u.washington.edu>
2589 * tutorial/tutorial.tex: Update version statement to 4.2
2591 * src/version.c src/version.h: Global (char *)compile_options.
2593 * src/show.c (show_version): Save the configuration options string
2594 produced for "show version long" in (char *)compile_options. If called
2595 as show_version(NULL), do this and nothing else.
2597 * src/plot.c (main): Call show_version() on program entry in both
2598 interactive and non-interactive mode so that it initializes the
2599 compile_options string.
2601 * src/eval.c (update_gpval_variables): New udv GPVAL_COMPILE_OPTIONS
2602 that makes the compile_options string available to the user.
2604 2006-08-05 Daniel Sebald <daniel.sebald@ieee.org>
2606 * src/history.c: Built-in readline history command was losing one
2607 saved entry every time. Fix the start point for the save.
2610 2006-08-04 Ethan A Merritt <merritt@u.washington.edu>
2612 * term/pdf.trm term/post.trm term/emf.trm term/cgm.trm
2613 term/metapost.trm: term->options() should not reset the terminal to
2614 its default values if it is called from "set termoption" rather than
2618 * docs/gnuplot.doc: Fix typo and update example commands to use
2619 exists("Foo") rather than define(Foo).
2621 * src/eval.c (update_gpval_variables): Store PATCHLEVEL as a string if
2622 possible, so that people can use this as an identifier for customized
2625 2006-08-03 Ethan A Merritt <merritt@u.washington.edu>
2627 * term/pdf.trm (PDF_set_color PDF_linetype PDF_filled_polygon):
2628 Implement the "mono" option, which up until now has not done anything
2629 other than failing to set new linetypes.
2632 2006-08-03 Petr Mikulik <mikulik@physics.muni.cz>
2634 * term/PostScript/prologues.h: Regenerated.
2636 * term/PostScript/ps_header.sh: Force always the same sorting.
2638 * term/post.trm term/PostScript/prologue.ps: Move "Blacktext {} if" into
2639 the definitions of {M}{LCR}show, to avoid it directly in the postscript
2642 2006-08-01 Ethan A Merritt <merritt@u.washington.edu>
2644 * src/datafile.c (df_readascii): Allow a string-valued function
2645 to provide the time/date string for interpreting axis coordinates
2646 given after 'set {xyz}data time'.
2649 2006-07-31 Timothee Lecomte <timothee.lecomte@ens.fr>
2651 * README.1ST: Update notes on the gd library.
2653 2006-07-31 Ethan A Merritt <merritt@u.washington.edu>
2655 * term/gd.trm (PNG_linetype): Fix off-by-one error in checking for
2656 minimum legal linetype. Could conceivably have caused a segfault.
2658 * demo/rectangle.dem demo/html/index.save: Update demo for 4.2
2660 2006-07-30 Ethan A Merritt <merritt@u.washington.edu>
2662 * docs/gnuplot.doc (Known Bugs): The 'nohidden3d' options does
2663 not work for parametric curves. Bug #1531432.
2665 2006-07-30 Shigeharu Takeno <shige@iee.niit.ac.jp>
2667 * docs/gnuplot-ja.doc docs/term-ja.diff:
2668 Sync Japanese documentation to recent changes in English files.
2670 2006-07-30 Timothee Lecomte <timothee.lecomte@ens.fr>
2672 * term/post.trm: Reword the doc about the prologue files, so that we do
2673 not need the #ifdef GNUPLOT_PS_DIR, and so that the use of the
2674 environment variable GNUPLOT_PS_DIR is always documented since it is
2677 2006-07-30 Daniel Sebald <daniel.sebald@ieee.org>
2679 * docs/gnuplot.doc: Format norm()/invnorm() info for 80 characters.
2681 2006-07-29 Ethan A Merritt <merritt@u.washington.edu>
2683 * configure.in: Remove warning about needing a patch for libreadline
2684 (not relevant to libreadline version 5).
2686 * docs/gnuplot.texi: Update to match current documentation.
2688 2006-07-29 James R. Van Zandt <jrv@vanzandt.comcast.net>
2690 * docs/gnuplot.doc: clarify definitions of functions norm() and igamma()
2692 2006-07-29 Timothee Lecomte <timothee.lecomte@ens.fr>
2694 * docs/gnuplot.doc: Another round of additions to the "news" section
2697 * src/plot.c (main): Fix parsing of "-persist" for the wxWidgets
2698 terminal when X11 is not defined, and when _Windows is defined.
2700 * term/ai.trm (TERM_HELP): Add notice that the terminal is outdated
2701 and that post should be used instead.
2703 2006-07-28 Timothee Lecomte <timothee.lecomte@ens.fr>
2705 * docs/gnuplot.doc: Add details about new features in 4.2 with full
2706 sentences and following the same format as 4.0 new features.
2708 * src/command.c (rlgets) [HAVE_LIBREADLINE]: Add an extra string
2709 comparison not to remove false duplicates from the history.
2712 2006-07-28 Ethan A Merritt <merritt@u.washington.edu>
2714 * tutorial/Makefile.am.in: Set environmental variable GNUTERM to latex
2715 before running gnuplot on the tutorial demos. Bypasses any potential
2716 conflicts of default terminal type with currently installed terminals.
2719 * src/misc.c (lp_parse parse_colorspec): Incorrect parsing of linetype
2720 colorspec if the colorspec was not the last thing on the command line.
2723 * term/emf.trm: Implement "set term emf ... size XX,YY".
2725 * term/post.trm term/dumb.trm: Update terminal description
2727 2006-07-27 Ethan A Merritt <merritt@u.washington.edu>
2729 * term/pslatex.trm (EPSLATEX_set_color): If the color is specified
2730 by linetype, fall back to PS_linetype for monochrome/grayscale plots.
2733 2206-07-27 Timothee Lecomte <timothee.lecomte@ens.fr>
2735 * docs/gnuplot.doc (x11_mouse): Reword the section about possible hangs
2736 when piping from /dev/null to reflect the 4.2 behaviour where mouse is
2737 turned on by default.
2739 * src/plot.c (main):
2740 * src/wxt_gui.c (wxt_atexit):
2742 Move the code parsing **argv for "-persist" from wxt_atexit() to
2743 main(). X11_args() parses it too in main() and removes the tokens that
2744 it recognizes from **argv, so we need to do it before that happens.
2745 Also avoid processing of the mouse events when the wxt terminal is not
2746 the current active one at exit time.
2748 2006-07-27 Shigeharu Takeno <shige@iee.niit.ac.jp>
2750 * docs/gnuplot-ja.doc docs/term-ja.diff:
2751 Sync Japanese documentation to recent changes in English files.
2753 2006-07-26 Per Persson <persquare@mac.com>
2754 * term/aquaterm.trm: Made UTF8 the default encoding for AquaTerm.
2756 2006-07-26 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2758 * tutorial/Makefile.am.in (RUN_GNUPLOT): Can the .plt.tex command
2759 sequence into this new macro.
2760 (.plt.tex): Use the new macro. Ged rid of the @ marker that hides
2761 the gnuplot invocation, while at it.
2762 (eg7.eps): New rule using the macro, to ensure make knows how to
2763 make the .eps file, even if the .tex output is still present.
2765 2006-07-26 Timothee Lecomte <timothee.lecomte@ens.fr>
2767 * tutorial/.cvsignore: Add *.eps and test.tex to the list of files
2768 to be ignored by CVS.
2770 2006-07-25 Timothee Lecomte <timothee.lecomte@ens.fr>
2772 * term/README: Change IMAGE_DRIVER to the true WITH_IMAGE.
2774 2006-07-24 Timothee Lecomte <timothee.lecomte@ens.fr>
2776 * term/wxt.trm (wxt_options): Fix wrong test on tri-state variable.
2778 2006-07-23 Timothee Lecomte <timothee.lecomte@ens.fr>
2780 * docs/gnuplot.doc (Syntax): Change wording to avoid reference to
2781 `enhanced postscript`.
2783 2006-07-22 Timothee Lecomte <timothee.lecomte@ens.fr>
2785 * docs/gnuplot.doc: Add here and there some references to the wxWidgets
2786 terminal, where appropriate.
2787 * term/post.trm (00psglobal): Remove reference to 'if compiled with
2789 * term/post.trm (epslatex): Change reference from 'set ticscale' to
2792 2006-07-21 Ethan A Merritt <merritt@u.washington.edu>
2794 * src/gplt_x11.c term/x11.trm term/wxt.trm: Make x11 and wxt share a
2795 common syntax for switching between "quit = q" and "quit = ctrl-q"
2796 behaviour from the command line:
2797 set term foo {{no}ctrlq}
2799 2006-07-20 Ethan A Merritt <merritt@u.washington.edu>
2801 * src/eval.c src/eval.h src/plot.c: Add a pre-defined udv NaN that is
2802 guaranteed to evaluate as NaN. This provides a convenient way to define
2803 a user function that explicitly returns NaN under some conditions.
2806 2006-07-20 Shigeharu Takeno <shige@iee.niit.ac.jp>
2808 * docs/gnuplot-ja.doc: Sync to current English version.
2810 2006-07-20 Ethan A Merritt <merritt@u.washington.edu>
2812 * term/*.trm: Revert patchset of 2006-07-06
2813 Restore explicit help entries for "set term foo ...".
2814 Daniel has a patch to help.c which would obviate this fix, but I judge
2815 that had better wait til after 4.2. This returns us to a state that
2816 was satisfactory for a long time.
2818 * docs/term-ja.diff: EAM - Modify patch so that it applies without error,
2819 but it still needs to be updated to track the recent changes to post.trm
2820 that add a section describing GNUPLOT_PS_DIR.
2822 2006-07-18 Timothee Lecomte <timothee.lecomte@ens.fr>
2824 * src/wxterminal/wxt_gui.h (wxtPanel): New state variable
2827 * src/wxterminal/wxt_gui.cpp (wxt_set_cursor): Handle the new flags -3
2828 and -4 for "line from ruler to current mouse position".
2829 (OnMotion): Redraw on mouse motionto update the line to ruler.
2830 (Draw): Draw a line from the ruler to current position when asked to.
2832 2006-07-18 Ethan A Merritt <merritt@u.washington.edu>
2834 * term/post.trm: Add help-file sections describing the PostScript
2835 prolog processing, and the environmental variable GNUPLOT_PS_DIR.
2837 * term/post.trm: Add a %%BeginProlog line to the output stream.
2839 * docs/Makefile.in: Define GNUPLOT_PS_DIR so that the corresponding
2840 documentation is processed (Timothee Lecomte).
2842 * src/plot3d.c (eval_3dplots): Unnecessary initialization to quiet
2843 spurious compiler warning.
2845 2006-07-18 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
2847 * config/makefile.oww (TERMFLAGS): Add -DGNUPLOT_PS_DIR flag.
2848 (GNUPLOT_PS_DIR): Define the relative PostScript path.
2850 * config/makefile.mgw: Add a line to help Emacs detect this is a
2852 (term.$(O)): -DGNUPLOT_PS_DIR shouldn't really be down here.
2853 (TERMFLAGS): Move the -DGNUPLOT_PS_DIR flag in here.
2855 2006-07-18 Petr Mikulik <mikulik@physics.muni.cz>
2857 SF Patch [1520821] line from ruler to current mouse position if polar
2860 * src/mouse.c term/README: Two new flags for term->set_cursor(flag,...):
2861 -3 = draw line between ruler and current mouse position,
2862 -4 = don't draw (erase) line between ruler and current mouse position.
2863 They are issued when mousing with displayed ruler and showing polar
2864 distance or tangent.
2866 * src/gplt_x11.c: New plot variables ruler_lineto_{on|x|y}, and function
2867 DrawLineToRuler(plot) to draw and erase line between ruler and current
2868 mouse position. This implements calls of set_cursor(flag,...) for
2871 * src/win/wgraph.c: Same as for gplt_x11.c, just with ruler_lineto
2874 2006-07-17 Timothee Lecomte <timothee.lecomte@ens.fr>
2876 * term/post.trm (PS_dump_prologue_file): Modify the Windows code
2877 to use GNUPLOT_PS_DIR as the relative path
2879 * config/makefile.mgw: Add an entry to define GNUPLOT_PS_DIR.
2881 2006-07-17 Bastian Maerkisch <bmaerkisch@web.de>
2883 * term/post.trm (PS_dump_prologue_file): OS/2 code to look
2884 for PostScript prologue files relatively to the executable path.
2886 2006-07-17 Ethan A Merritt <merritt@u.washington.edu>
2888 * NEWS docs/gnuplot.doc: Update list of known bugs, and add index
2889 entries to help find them in the docs.
2891 * src/plot2d.c (get_data): Remove debugging statement that escaped
2894 2006-07-16 Ethan A Merritt <merritt@u.washington.edu>
2896 * term/pslatex.trm (EPSLATEX_set_color): Filter out redundant commands
2897 to change the color in the *.tex output stream by buffering each
2898 set_color command, and only sending the most recent one if necessary at
2899 the time the next TeX plot element is sent.
2902 * docs/gnuplot.doc: Document the new FIT_* user variables, and clarify
2903 the use of locale settings.
2905 2006-07-15 Timothee Lecomte <timothee.lecomte@ens.fr>
2907 * term/PostScript/prologues.h term/PostScript/ps_header.sh
2908 term/PostScript/README: Set up an automated system for encapsulating
2909 the external PostScript prologue files back into a header for inclusion
2910 in-line in post.trm if necessary.
2912 * term/post.trm: If GNUPLOT_PS_DIR is defined, then load the prologue
2913 data at run-time from the externally maintained files in that directory.
2914 If GNUPLOT_PS_DIR is not defined, then include the equivalent text data
2915 as static arrays at compile time.
2917 * config/makefile.mgw: Define some GNUPLOT_PS_DIR.
2919 * src/win/winmain.h: Declare szModuleName as extern
2920 (EAM - what is this???).
2924 2006-07-15 Ethan A Merritt <merritt@u.washington.edu>
2926 * src/fit.c (regress): Export user-visible variables from the fit.
2927 FIT_NDF : Number of degrees of freedom
2928 FIT_WSSR : Weighted sum-of-squares residual
2929 FIT_STDFIT : sqrt(WSSR/ndf), called "rms of residuals" in the log file
2930 FIT_CONVERGED : 1 if the previous fit converged; 0 otherwise
2932 2006-07-15 Daniel Sebald <daniel.sebald@ieee.org>
2933 * src/command.c (history_command): Remove recursive function call to
2934 avoid problem with "flag" being in incorrect state if the recalled
2935 command from history fails. Now use approach where command from
2936 history is parsed to check if it itself is also history.
2938 2006-07-14 Timothee Lecomte <timothee.lecomte@ens.fr>
2940 * src/wxterminal/gp_cairo.c: Respect ISO C90 standard (mainly move
2941 declarations to beginning of functions).
2943 2006-07-14 Ethan A Merritt <merritt@u.washington.edu>
2945 * term/post.trm (PS_dump_prologue_file): Try harder to expand short
2946 file name into legal VMS or Windows path+file. Give more informative
2947 error messages if the file cannot be found.
2949 2006-07-14 Juergen Wieferink <wieferink@freenet.de>
2951 * src/eval.c (fill_gpval_string): Remove cast to (char *) by correcting
2952 a dereference of the string value.
2954 2006-07-13 Juergen Wieferink <wieferink@freenet.de>
2956 * src/eval.c (fill_gpval_string): Do not risk calling gpfree_string
2957 on uninitialized udv.
2959 * src/eval.c (update_gpval_variables): Treat GPVAL_TERM just like all
2960 the other GPVAL_* variables.
2962 * standard.c standard.h (f_exists): Allow to compile with
2963 ./configure --disable-stringvariables
2965 2006-07-12 Ethan A Merritt <merritt@u.washington.edu>
2967 * configure.in: Enable HIDDEN3D_QUADTREE by default.
2969 * term/post.trm (PS_linetype): Additional optimization from not forcing
2970 an absolute move if the linetype change has been optimized away.
2972 * term/pslatex.trm (EPSLATEX_linetype): Step back from over-general test
2973 for unnecessary linetype change. Forward it to PS_linetype for the
2974 actual decision. Without this, a pure linewidth change or a pure
2975 dash style change are incorrectly ignored.
2978 2006-07-12 Timothee Lecomte <timothee.lecomte@ens.fr>
2980 * demo/Makefile.am.in:
2983 Rename temporary *.dat files to *.tmp to prevent them to be included by
2986 2006-07-11 Ethan A Merritt <merritt@u.washington.edu>
2988 * term/pslatex.trm (EPSLATEX_set_color): Restore support for color
2989 text set using fractional palette values. If the terminal is in mono
2990 mode, or has the blacktext option, the fractional text color remains
2994 2006-07-11 Per Persson <persquare@mac.com>
2996 * term/aquaterm.trm: Made aqua terminal respect font requests of the
2997 form: font "<fontface>{,<fontsize>}", old syntax still supported too.
2999 2006-07-11 Petr Mikulik <mikulik@physics.muni.cz>
3001 * config/makefile.cyg config/makefile.mgw config/makefile.nt: #define
3002 EAM_OBJECTS and HIDDEN3D_VAR_PTSIZE.
3004 2006-07-10 Ethan A Merritt <merritt@u.washington.edu>
3006 * demo/mouselabels.dem demo/mouselab_1.dem demo/mouselab_2.dem:
3007 New demo using GPVAL_* variables and mouse/keystroke interaction to
3008 achieve interactive placement of plot labels. Tested for x11 and wxt.
3010 * demo/mousevariables.dem demo/keystroke.dem(removed):
3011 Remove the keystroke part of this demo, since this feature is now
3012 demonstrated more usefully by mouselabels.dem
3014 * src/eval.c: Allow both if(exists("foo")) and if(exist("foo")).
3015 The latter is what octave uses.
3017 2006-07-09 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
3019 * demo/Makefile.am.in (CLEANFILES): Remove stringvar.tmp.
3021 * tutorial/Makefile.am.in (CLEANFILES): Fix up list of created
3022 files to be cleaned.
3023 (.plt.tex): Allow vpath builds.
3024 (.eps.pdf): New rule to fix pdf build of tutorial.
3025 (tutorial.dvi): Add dependency on eg7.eps.
3026 (tutorial.pdf): Add dependency on eg7.pdf
3028 * src/win/wtext.c: Fix mixed-up line endings.
3030 * docs/gnuplot.doc: Repair some blank-only lines. Again.
3032 2006-07-08 Timothee Lecomte <timothee.lecomte@ens.fr>
3034 * configure.in: Always check for Cairo rendering support in Pango, and
3035 add the corresponding linking flags to WX_LIBS.
3037 * src/wxterminal/gp_cairo.c (gp_cairo_enhanced_flush): Initialize
3038 overprinted_width to avoid gcc warning.
3040 * term/wxt.trm (wxt_options): Initialize font_setting to avoid gcc
3043 2006-07-08 Ethan A Merritt <merritt@u.washington.edu>
3045 * src/parse.c: Revert to parse.c version 1.44 (10 Jun 2006).
3046 This does away with dead code left after yesterday's partial
3049 * term/post.trm (PS_linetype PS_set_color): Restore long-time commented
3050 out test for redundant linetype commands. Don't "change" linetype if the
3051 new one is the same as the current one. term->set_color must also
3052 invalidate the previous linetype so that the next call to term->linetype
3056 2006-07-07 Shigeharu Takeno <shige@iee.niit.ac.jp>
3058 * docs/gnuplot-ja.doc docs/term-ja.diff:
3059 Sync Japanese documentation to recent changes in English files.
3061 2006-07-07 Daniel Sebald <daniel.sebald@ieee.org>
3063 * src/parse.c (parse_primary_expression): Partially back out patch of
3064 2006-06-11. Do not check number of variables passed to a user function
3065 at the time of parsing - only at time of evaluation.
3068 2006-07-07 Ethan A Merritt <merritt@u.washington.edu>
3070 * src/help.c (FindHelp): Add missing pair of brackets to disambiguate
3073 * src/command.c (history_command): Fix segfault if re-execution of a
3074 previous command terminates via int_error().
3077 * demo/rectangle.dem: Add reset at end, and prompts at 'pause -1'.
3079 * src/plot2d.c (get_data): HISTOGRAM plot styles must leave a slot for
3080 all entries, even if they are flagged as DF_MISSING. Otherwise the
3081 histogram plot elements do not line up properly.
3083 2006-07-06 Daniel Sebald <daniel.sebald@ieee.org>
3085 * docs/gnuplot.doc term/*.trm: Remove redundant help keys; i.e. those
3086 that are distinguished only by one being a short form of the other.
3087 No change in help or documentation behavior is intended.
3090 ?set term cgm %% delete this one
3092 2006-07-06 Ethan A Merritt <merritt@u.washington.edu>
3094 * term/pslatex.trm (EPSLATEX_linetype EPSLATEX_set_color):
3095 Keep track of last color and/or linetype set, and filter out
3096 duplicate requests for the same setting. It remains true that the
3097 color change command is sent to both the *.eps and *.tex output stream,
3098 whereas in general only one of the two needs to see it.
3101 * tutorial/tutorial.tex tutorial/eg7.plt: Make the file names
3102 of the 7th example plot match the other six examples.
3104 2006-07-07 Timothee Lecomte <timothee.lecomte@ens.fr>
3106 * src/wxterminal/wxt_gui.h:
3107 * src/wxterminal/wxt_gui.cpp (wxtPanel::Draw):
3108 (wxtPanel::DrawToDC):
3109 (wxtPanel::OnPaint):
3110 Small rework of the double-buffering to fully comply with wxWidgets
3113 2006-07-07 Petr Mikulik <mikulik@physics.muni.cz>
3115 * src/set.c docs/gnuplot.doc: New options
3116 'set mouse {noruler|ruler {at x,y}}'.
3118 * src/mouse.h src/mouse.c: New function set_ruler() to (un)set ruler
3119 (at a given position).
3121 2006-07-06 James R. Van Zandt <jrv@vanzandt.comcast.net>
3123 * demo/bivariat.dem:
3124 - Adjust the step size so the range of integration is an integral
3126 - Use Simpson's rule rather than just taking the function value at
3127 one end of each step
3128 - Add points from the real erf(x) to the first plot, for comparison
3129 - For the second plot, define the integrand f(x)=cos(x)
3130 That way, the integral is sin(x) instead of being offset by a
3131 constant of integration
3132 - For the last plot, use "with impulses" to make the pattern more
3133 apparent, and because the function is only defined over the integers
3135 2006-07-06 Petr Mikulik <mikulik@physics.muni.cz>
3137 * src/set.c (set_mouse) docs/gnuplot.doc: Command 'set mouse
3138 polardistance{deg|tan}' to flip between the two possibilities
3139 of displaying polar distance.
3141 2006-07-05 Ethan A Merritt <merritt@u.washington.edu>
3143 * term/pdf.trm: Add {size xx,yy} option, exactly parallel to the
3144 option recently added for PostScript. Size can be given in inches
3147 2006-07-05 Bastian Maerkisch <bmaerkisch@web.de>
3149 * config/makefile.nt: Add /DWIN32 to CFLAGS.
3151 2006-07-04 Daniel Sebald <daniel.sebald@ieee.org>
3153 * demo/image.dem: Remove obsolete warning about terminal support.
3155 2006-07-04 Bastian Maerkisch <bmaerkisch@web.de>
3157 * term/win.trm (WIN_enhanced_open): (2nd try)
3158 Reset to _default_ font, not _current_ font!
3161 2006-07-04 Ethan A Merritt <merritt@u.washington.edu>
3163 * term/gd.trm (PNG_justify_text): Move the conditional test for
3164 HAVE_GD_TTF inside the PNG_justify_text() routine, rather than
3165 maintaining it in parallel in the PNG/JPEG/GIF TERM_TABLE entries.
3166 Actually, we were failing to maintain it in parallel, causing
3169 2006-07-04 Petr Mikulik <mikulik@physics.muni.cz>
3171 * src/mouse.c (builtin_toggle_ruler, turn_ruler_off): New autogenerated
3172 variables MOUSE_RULER_X and MOUSE_RULER_Y.
3174 * src/mouse.c (GetRulerString, builtin_toggle_polardistance): Let polar
3175 coordinates show either (distance,angle) or (distance,tangent) after
3176 multiple clicks of the default hotkey '5'.
3178 * src/mouse.c (GetRulerString): Support polar coordinates in the
3179 mouse&ruler message string also for log-log plots.
3181 2006-07-02 Daniel Sebald <daniel.sebald@ieee.org>
3183 * src/show.c (show_command): Place in some messages about "show data"
3184 and "show linestyle" being deprecated.
3186 2006-06-30 Ethan A Merritt <merritt@u.washington.edu>
3188 * demo/image.dem demo/demo.edf: Set binary flag in cvs repository.
3189 cvs admin -kb demo/image.dem demo/demo.edf
3191 2006-06-30 Petr Mikulik <mikulik@physics.muni.cz>
3193 * src/breaders.c (edf_filetype_function): Don't print a debugging
3196 * src/eval.c (update_gpval_variables): Added automatic read-only
3197 variables GPVAL_VERSION and GPVAL_PATCHLEVEL.
3199 2006-06-29 Bastian Maerkisch <bmaerkisch@web.de>
3201 * term/win.trm (WIN_enhanced_open): Reset to _default_ font, not
3202 _current_ font! Bug #1510055

3206 * src/set.c src/show.c: Less alarming error message if deprecated syntax
3207 is detected. Undeprecate "set key {below|above}".
3210 * tutorial/Makefile.am.in eg4.plt eg5.plt eg6.plt eg7.plt test.plt
3211 tutorial.tex header.tex makefile.dst linepoin.plot (removed):
3212 Replace deprecated syntax in tex example plots. Add an epslatex sample.
3214 * src/save.c: Add missing newline after 'set pm3d depthorder'.
3216 * docs/gnuplot.doc docs/gnuplot-ja.doc: Refer to current version as
3217 4.2 rather than 4.1.
3219 2006-06-29 Daniel Sebald <daniel.sebald@ieee.org>
3221 * demo/airfoil.dem histograms.dem histograms2.dem image.dem multiplt.dem
3222 random.dem simple.dem starmap.dem:
3223 Small changes to ensure demos do not use deprecated syntax.
3225 * docs/gnuplot.doc: Clean up "set title" and "set xlabel" and remove
3226 any examples with non up-to-date syntax.
3228 2006-06-29 Petr Mikulik <mikulik@physics.muni.cz>
3230 SF Patch [1488448] User-available GPVAL_ variables
3232 * NEWS docs/gnuplot.doc src/command.c src/eval.c src/eval.h src/plot.c
3233 src/plot2d.c src/plot3d.c src/save.c src/set.c src/show.c src/unset.c:
3234 New routine update_gpval_variables() to create and update autogenerated
3235 read-only GPVAL_ variables, and its callers. New command option
3236 'show variables all'.
3238 2006-06-28 Daniel Sebald <daniel.sebald@ieee.org>
3240 * src/history.c (write_history_n): Account for the case where the
3241 number of history entries is less than what the user asked for.
3243 2006-06-28 Ethan A Merritt <merritt@u.washington.edu>
3245 * src/term.c (change_term) term/x11.trm: The x11 terminal driver has
3246 been carrying around two copies of TERM_TABLE, one named "x11" and
3247 the other named "X11". But the "X11" copy has suffered from bit rot.
3248 Delete this redundant copy, and instead replace "X11" with "x11"
3249 at the time the "set term" request is processed.
3251 2006-06-27 Daniel Sebald <daniel.sebald@ieee.org>
3253 * src/unset.c (unset_minitics, reset_command): Change action of
3254 unset_minitics to MINI_OFF and set to MINI_DEFAULT after calling
3255 from reset_command().
3258 2006-06-27 Shigeharu Takeno <shige@iee.niit.ac.jp>

3271 * m4/pkg.m4: New files containing the pkg-config macros.
3273 2006-06-26 Ethan A Merritt <merritt@u.washington.edu>
3275 * term/wxt.trm: Add index point for "help set term wxt".
3277 * configure.in src/variable.c: Only invoke kpsexpand if configuration
3278 option --with-kpsexpand is chosen at build time.
3281 2006-06-26 Daniel Sebald <daniel.sebald@ieee.org>
3283 * src/help.c (FindHelp): Fixed bug introduced on 2006-06-23 where
3284 strcpy() overwrote keyword, inadvertently losing the subtopic string.
3285 Now expand all abbreviated sub-keywords until end of keyword string.
3287 * src/util.c (lower_case): Fix off-by-one bug in characters treated.
3289 2006-06-25 Ethan A Merritt <merritt@u.washington.edu>
3291 * src/plot2d.c (get_data): If a data field matches the current setting
3292 of 'set datafile missing "foo"', then do not interrupt the plotted line
3293 spanning the adjacent points in the plot. This was the behavior in
3294 version 3.7, and is what the documents describe, but has not been the
3295 case in version 4.0.
3296 Bugs #775810 #918793 #969322 #1403945
3298 2006-06-24 Ethan A Merritt <merritt@u.washington.edu>
3300 * src/datafile.c: Whitespace cleanup, comments.
3302 * demo/contours.dem demo/vector.dem: Update demo to use "set view map".
3304 2006-06-23 Daniel Sebald <daniel.sebald@ieee.org>
3306 * src/help.c (FindHelp): Return a pointer to an empty help key if the
3307 user help string is ambiguous. Change the len computation from strlen()
3308 to strcspn() so that non ambiguous, sub-optioned strings work.
3309 (help): Only PrintHelp if text exists to prevent blank line at output.
3311 2006-06-23 Daniel Sebald <daniel.sebald@ieee.org>
3313 * demo/image.dem: Clean up missing quotes. Removed some resets so
3314 that the palette doesn't change except when necessary.
3316 * src/graphics.dem src/set.c: Cosmetic changes.
3318 2006-06-22 Ethan A Merritt <merritt@u.washington.edu>
3320 * configure.in src/datafile.c (df_readline): Check input values
3321 against NaN, but only if the system supports the isnan() test.
3322 NaN input values are treated as UNDEFINED.
3325 2006-06-21 Ethan A Merritt <merritt@u.washington.edu>
3327 * demo/scatter2.bin demo/sine.bin demo/using.bin demo/blutux.rgb:
3328 Flag these files as binary in the CVS repository
3329 cvs admin -kb *.bin *.rgb
3330 Hopefully this will fix image.dem under Windows
3332 2006-06-21 Timothee Lecomte <timothee.lecomte@ens.fr>
3334 * term/wxt.trm: Small correction in TERM_HELP.
3336 2006-06-20 Timothee Lecomte <timothee.lecomte@ens.fr>
3338 * src/wxterminal/wxt_gui.cpp: Small cleanups to avoid -Wall warnings.
3340 2006-06-20 Ethan A Merritt <merritt@u.washington.edu>
3342 * src/plot.c (main) src/term.c (init_terminal): Revisit fix of
3343 2004-08-25 - call term->option() on entry if the default terminal is set
3344 from GNUTERM. We have only been doing this for the libgd terminals, but
3345 it turns out to be necessary for PostScript also, and probably others.
3348 * demo/stringvar.dem demo/html/index.save demo/html/Makefile:
3349 Modify the stringvar demo for use with webify, and add it to the
3352 * src/set.c (load_tic_series): Fix parsing error that had the effect
3353 of requiring an explicit end point for the tic series unless this was
3354 the last thing on the command line.
3356 2006-06-19 Ethan A Merritt <merritt@u.washington.edu>
3358 * term/post.trm: Initialize PS_default_font to "Helvetica,14".
3359 In the worst case scenario, this guarantees a non-zero font size
3360 and an actual PostScript font.
3363 2006-06-19 Timothee Lecomte <timothee.lecomte@ens.fr>
3365 * configure.in (GNUPLOT_PS_DIR): Do not pass GNUPLOT_PS_DIR in
3368 * src/Makefile.am: Pass GNUPLOT_PS_DIR as a CPPFLAG.
3370 * term/Makefile.am.in: Install the *.ps files the automake way.
3372 * config/makefile.mgw (WXT): Do not install the PNG icons of the
3373 wxWidgets terminal (now embedded).
3375 2006-06-19 Ethan A Merritt <merritt@u.washington.edu>
3377 * src/plot3d.c (get_3ddata): After reading in the data points, check
3378 that the axis ranges are legal. If the input data contains NaN or Inf
3379 then the axis scaling may fail.
3382 2006-05-18 Bastian Maerkisch <bmaerkisch@web.de>
3384 * src/win/wtext.c: Add mouse wheel scroll support for text window.
3386 2006-06-18 Shigeharu Takeno <shige@iee.niit.ac.jp>
3388 * docs/gnuplot-ja.doc docs/README.ja docs/term-ja.diff
3389 src/win/README.win-ja src/win/wgnuplot-ja.mnu:
3390 Sync Japanese documentation to recent changes in English files.
3392 2006-06-18 Ethan A Merritt <merritt@u.washington.edu>
3394 * src/show.c (show_version): List additional configuration options.
3395 Make the show version output more compact (25 lines).
3397 * term/emf.trm (EMF_linetype EMF_dashtype): It is necessary to set the
3398 line color and dash type every time either is changed.
3401 2006-06-17 Timothee Lecomte <timothee.lecomte@ens.fr>

3410 * src/wxterminal/bitmaps/png/replot_png.h:
3411 New files containing the translation of the binary PNG files into
3412 C arrays to be included in the source code.
3414 * src/wxterminal/bitmaps/png/README.embedding:
3415 Text file briefly explaining the purpose of the embedded PNG files.
3417 * src/wxterminal/wxt_gui.cpp (wxtApp::OnInit): Remove the code to load
3418 the PNG files from standard paths (unreliable). Replace by the loading
3419 of the embedded files.
3420 (wxtPanel::UpdateModifiers): New routine to compare and update the
3421 state of the modifier keys as known by the core. It replaces the
3422 unreliable tracking of the press and release events. All wxMouseEvent
3423 and wxKeyEvent processing methods updated.
3424 (wxtPanel::OnKeyEvent):
3427 New variable wxt_ctrl to handle 'q' and <space>.
3429 * src/wxterminal/wxt_gui.h:
3430 * src/wxterminal/wxt_term.h:
3431 Update prototypes and included wxWidgets headers according to the above
3434 * term/wxt.trm (wxt_options): New terminal option '{no}ctrl'.
3435 (TERM_HELP): Updated.
3437 * src/Makefile.am (png_DATA): Do not install the PNG icons.
3439 2006-06-17 Ethan A Merritt <merritt@u.washington.edu>
3441 * demo/Makefile.am.in: Clean up temp.dat
3443 * share/Makefile.am: Attempt to install/uninstall Gnuplot.app-defaults
3446 * docs/Makefile.in: Add Japanese language files to EXTRA_DIST
3448 * docs/gnuplot.doc: Replace old "bugs" section with current list of
3449 known bugs and limitations.
3451 * docs/gnuplot.doc: Add pointers to 'set pm3d depthorder' in the
3452 discussion of hidden surface removal.
3454 * docs/gnuplot.texi docs/doc2texi.el: Regenerate gnuplot.texi
3456 2006-06-16 Timothee Lecomte <timothee.lecomte@ens.fr>
3458 * src/command.h: Add missing statement about copyright holders (i.e
3459 the same as command.c, as command.h was created from this file).
3461 * src/wxterminal/Makefile.am: New Makefile used to put all the
3462 wxterminal source files and bitmaps in the 'make dist' target.
3464 * src/Makefile.am (SUBDIRS): Add wxterminal to take the new Makefile.am
3467 * configure.in (AC_OUTPUT): Include src/wxterminal/Makefile in the list
3470 2006-06-15 Ethan A Merritt <merritt@u.washington.edu>
3472 * src/show.c (show_version): Add the rest of the non-driver
3473 configuration option choices to the output of 'show version long'.
3475 2006-06-15 Shigeharu Takeno <shige@iee.niit.ac.jp>
3477 * docs/gnuplot-ja.doc docs/README.ja term-ja.diff: Japanese translation
3478 of user manual and instructions for building the help system from it.
3480 * src/win/wgnuplot-ja.mnu /src/win/README.win-ja: Instructions for
3481 building a Japanese language versino of wgnuplot for Windows, and a
3482 corresponding set of menus.
3484 2006-06-15 Timothee Lecomte <timothee.lecomte@ens.fr>
3486 * src/wxterminal/gp_cairo.c: Fix a warning about gp_alloc() by
3489 2006-06-15 Ethan A Merritt <merritt@u.washington.edu>
3491 * demo/all.dem demo/html/index.save demo/html/Makefile:
3492 Add demo hidden2.dem illustrating 'set pm3d depthorder'.
3494 2006-06-15 Johannes Zellner <johannes@zellner.org>
3496 * src/save.c src/set.c src/show.c src/tables.c src/tables.h:
3497 New option 'set p3md depthorder' to request depth-ordering of
3500 * src/graph3d.c: TBOOLEAN pm3d_order_depth tracks the new option.
3502 * src/pm3d.c src/pm3d.h (pm3d_depth_queue_clear pm3d_depth_queue_flush)
3503 src/plot3d.c (calculate_set_of_isolines)
3504 src/color.h src/color.c (ifilled_quadrangle): New support routines.
3506 2006-06-14 Daniel Sebald <daniel.sebald@ieee.org>
3508 * src/color.c (make_palette) src/term.c (term_start_plot):
3509 Revert change of 9-Jun-2006, so that we are again optimizing color
3510 palette usage by avoiding unnecessary calls to term->make_palette().
3511 However, make the PostScript terminal an exception by invalidating
3512 the previous palette at the start of every plot.
3514 2006-06-14 Shigeharu Takeno <shige@iee.niit.ac.jp>
3516 * docs/faq-ja.tex: Japanese translation of faq.tex
3518 * NEWS docs/Makefile.in: Include faq-ja.tex in list of distributed
3521 2006-06-13 Daniel Sebald <daniel.sebald@ieee.org>
3523 * demo/stat.inc: Overhaul of routines to add variable arguments,
3524 range checking and verify integer when appropriate. The significant
3525 change is forcing some input vars to be an integer, rather than casting
3526 them to int() in the formulae. (There are proper plot styles like
3527 "steps" to work with discrete r.v.s.)
3529 * demo/prob.dem: Modified the discrete r.v. examples to look more like
3530 a mass function or scaled impulses. More varied examples to show
3531 various plotting features.
3533 * demo/prob2.dem demo/random.dem: Add input variables to p.d.f. and
3534 c.d.f. functions. Added new Maxwell demo to random.dem.
3536 * docs/gnuplot.doc: Added adjective "normalized" to igamma()
3538 2006-06-13 Ethan A Merritt <merritt@u.washington.edu>
3540 * src/gplt_x11.c: Move export selection flags outside the the
3541 USE_MOUSE conditional code. Bug #1505704
3543 * src/term_api.h: DEFAULT_LP_STYLE_TYPE to lt -1 (makes arrows
3544 default to black rather than red).
3547 2006-06-13 Daniel Sebald <daniel.sebald@ieee.org>
3549 * configure.in src/Makefile.am src/makefile.awc src/makefile.all:
3550 Add a configuration mechanism for including binary.c in list of
3551 gnuplot sources when appropriate.
3553 * src/bin_hook.c: Remove from source tree.
3555 2006-06-13 Timothee Lecomte <timothee.lecomte@ens.fr>
3559 * src/wxterminal/wxt_gui.cpp:
3560 * src/wxterminal/wxt_gui.h:
3561 * src/wxterminal/wxt_term.h:
3562 Fix failures when compiling the wxWidgets terminal with
3563 --disable-mouse, by putting more code and declarations inside #ifdef
3564 USE_MOUSE ... #endif
3566 2006-06-12 Ethan A Merritt <merritt@u.washington.edu>
3568 * configure.in: Move options marked EXPERIMENTAL to the end of the
3569 configuration summary printout. Remove EXPERIMENTAL label from
3572 2006-06-11 Timothee Lecomte <timothee.lecomte@ens.fr>
3574 * demo/utf8.dem: Issue a 'reset' at the end of the file, as other demos
3577 * src/wxterminal/gp_cairo.c (gp_cairo_draw_text): Use the Symbol to
3578 Unicode conversion step, as for the enhanced text mode.
3579 (gp_cairo_enhanced_flush): Small cleanup and fix a forgotten free().
3581 * term/wxt.trm (TERM_HELP): Document the font requirements properly, in
3582 particular how the Symbol font is handled and where the fonts are taken
3583 from. Layout the whole help text so that lines are smaller than 80
3586 2006-06-11 Daniel Sebald <daniel.sebald@ieee.org>
3588 * src/eval.h: Added number of variables to user defined function struct.
3590 * src/command.c (define): Recorded number of variables into udf entry.
3592 * src/parse.c (add_is_udf, is_ud_functin, add_udf):
3593 Slight rearranging of functions to allow code reuse.
3595 * src/parse.c (parse_primary_expression): Check if function used in
3596 command is user defined. If so, verify number of variables is correct.
3598 * src/internal.c (f_call, f_calln): Added tests to catch variable
3599 mismatch at time of evaluation.
3601 2006-06-10 Timothee Lecomte <timothee.lecomte@ens.fr>
3603 * docs/Mafefile.in (CORETERM): Add wxt.trm in the list of
3606 * docs/gnuplot.doc : Add mentions of `wxt` among other terminals when
3607 useful (mouse, raise, lower, image, set_output, fillstyles).
3609 * src/wxterminal/wxt_gui.cpp:
3610 Fix compilation with --disable-with-image.
3612 * src/wxterminal/wxt_gui.h:
3613 Fix compilation with --disable-with-image.
3616 * src/wxterminal/gp_cairo.c
3617 (gp_cairo_draw_polygon): Replace malloc by gp_alloc.
3618 (gp_cairo_draw_image): Likewise.
3619 (gp_cairo_convert_symbol_to_unicode): Likewise.
3621 2006-06-09 Ethan A Merritt <merritt@u.washington.edu>
3623 * src/eval.c src/eval.h src/internal.c src/internal.h src/parse.c
3624 src/standard.c src/standard.h docs/gnuplot.doc NEWS:
3626 Deprecate built-in pseudo-function `if defined(foo)`
3627 Replace it with string function exists("foo")
3628 The previous version (defined) tried to bypass normal expression
3629 parsing, but succeeded only for the simplest cases. This variant,
3630 although deprecated, is still supported by BACKWARDS_COMPATIBLE.
3631 The new version handles the full general case by using string variables.
3634 * src/color.c (make_palette): Revert optimization (18 Mar 2006) that
3635 only sent palette information for a plot if it had changed since the
3636 previous plot. This doesn't work for PostScript output, because the
3637 pages may be viewed out of order. Bugfix.
3639 2006-06-08 Timothee Lecomte <timothee.lecomte@ens.fr>
3641 * src/wxterminal/gp_cairo.h:
3642 * src/wxterminal/wxt_plot.h:
3643 * src/wxterminal/wxt_term.h:
3644 Remove "extern" for functions.
3646 2006-06-07 Timothee Lecomte <timothee.lecomte@ens.fr>
3648 * configure.in (--with-wx-config=PATH): Fix wrong variable name.
3650 * src/term.c (init_terminal) [WXWIDGETS]: Take DEFAULTTERM into account.
3652 * src/wxterminal/bitmaps/xpm/cross.xpm:
3653 * src/wxterminal/bitmaps/xpm/right.xpm:
3654 * src/wxterminal/bitmaps/xpm/rotate.xpm:
3655 * src/wxterminal/bitmaps/xpm/size.xpm:
3656 Write the hotspot coordinates directly in the cursor files.
3658 * src/wxterminal/wxt_gui.h (wxtApp::LoadCursor):
3659 * src/wxterminal/wxt_gui.cpp (wxtApp::LoadCursor):
3660 Remove hotpost arguments, take hotspot coordinates from the XPM files.
3661 (wxtApp::OnInit): Update calls to LoadCursor.
3663 * src/wxterminal/gp_cairo.h (current_xmax): Rename to the more
3664 meaningful device_xmax.
3665 (current_ymax): Rename to device_ymax.
3666 * src/wxterminal/gp_cairo.c: All callers changed.
3667 * src/wxterminal/wxt_gui.cpp: Likewise.
3669 2006-06-06 Ethan A Merritt <merritt@u.washington.edu>
3671 * configure.in src/setshow.h config/config.*: Move definition of
3672 BACKWARDS_COMPATIBLE into config.h and the various config.* files rather
3673 than setshow.h so that it is visible to all the source files.
3675 2006-06-06 Timothee Lecomte <timothee.lecomte@ens.fr>
3677 * src/wxterminal/gp_cairo.c (device_y): Fix computation of
3679 (gnuplot_y): Likewise.
3681 2006-06-05 Peter Weilbacher <paepse@users.sourceforge.net>
3683 SF Patch [1498727] Remove duplicate entries in GNU readline history
3685 * command.c (rlgets): Remove duplicate entries in GNU readline history.
3687 2006-06-04 Timothee Lecomte <timothee.lecomte@ens.fr>
3689 * src/wxterminal/gp_cairo.c: Add Id.
3690 * src/wxterminal/gp_cairo.h: Likewise.
3691 * src/wxterminal/gp_cairo_term.h: Likewise.
3692 * src/wxterminal/wxt_gui.cpp: Likewise.
3693 * src/wxterminal/wxt_gui.h: Likewise.
3694 * src/wxterminal/wxt_plot.h: Likewise.
3695 * src/wxterminal/wxt_term.h: Likewise.
3697 2006-06-04 Ethan A Merritt <merritt@u.washington.edu>
3699 * src/graphics.c (two_edge_intersect) Remove old debugging code.
3701 * src/graphics.c (edge_intersect plot_filled_curves): Bugfix.
3702 Fix clipping of filled curves. When a curve leaves the plot and
3703 reenters via a different plot edge, we must add dummy points at the
3704 intervening plot corners.
3706 * src/graphics.c (fill_missing_corners): New routine to support
3707 clipping of filled areas defined by a bounding curve.
3709 2006-06-01 Ethan A Merritt <merritt@u.washington.edu>
3711 * src/unset.c (reset_command): Abandon the idea of automatic garbage
3712 collection for undefined user variables. The problem with this is that
3713 user-defined functions may still hold pointers to them for later use.
3714 E.g.: f(x) = a+b; reset; print f(1) - oops, no more a or b.
3717 * demo/world.dat: Rearrange line segments to make more continuous
3718 boundaries. Now it almost works for filledcurves.
3720 2006-05-29 Michael Ritzert <ritzert@t-online.de>
3722 * term/Makefile.am.in: Look for the postscript files to be installed
3723 relative to $(srcdir).
3725 2006-05-26 Ethan A Merritt <merritt@u.washington.edu>
3727 * src/gadgets.c (clip_point): The code comments incorrectly described
3728 the bit values returned by clip_point().
3730 2006-05-24 Ethan A Merritt <merritt@u.washington.edu>
3732 * src/gplt_x11.c: Treat LT_AXIS linetype as dotted even if the
3733 terminal is 'set term x11 solid'. Do not try to set dash type or
3734 linewidth for LT_BACKGROUND because this will underflow the type arrays.
3737 * share/Gnuplot.app-defaults: Comment out settings for *ctrlq *raise
3738 and *background so that the default remains the same as having no
3741 2006-02-23 Timothee Lecomte <timothee.lecomte@ens.fr>
3743 * term/wxt.trm (TERM_HELP): Fix typos, thanks to Shigeharu Takeno.
3745 2006-05-22 Timothee Lecomte <timothee.lecomte@ens.fr>
3747 * term/vgagl.trm (VGAGL_init_keytable): Fix bug #1492341 by
3748 replacing sizeof() on an array of int (which gives an overflow
3749 by writing four times more than the size of the array) by the
3750 actual size of the array (KEYTABLE_SIZE).
3751 (VGAGL_truecolor): Declare as a TBOOLEAN instead of an integer,
3752 do not use the enums yes and no but TRUE and FALSE.
3753 (VGAGL_processing_graphics_events): Likewise.
3754 (VGAGL_interpolate): Likewise.
3755 (VGAGL_cursor_drawn): Likewise.
3756 (VGAGL_need_update): Likewise.
3757 (VGAGL_graphics_on): Likewise.
3759 2006-05-22 Lars Hecking <lhecking@users.sourceforge.net>
3761 * configure.in: Reformat and bugfix wxwidgets section.
3763 * docs/gnuplot.texi: Regenerated.
3765 * share/Makefile.am: Add EXTRA_DIST.
3767 * src/Makefile.am: Add wxterminal to EXTRA_DIST.
3769 * src/makefile.all, src/makefile.awc: Regenerated.
3771 * src/wxterminal/wxt_gui.cpp: Fix typos.
3773 * term/estimate.trm: Add cvs Id.
3775 2006-05-21 Daniel Sebald <daniel.sebald@ieee.org>
3777 * demo/random.dem: Examples to illustrate generating normal random
3778 data, generating data points not linked to grid using table,
3779 setting the contour lines to the same color as surface, and
3780 creating histograms.
3782 2006-05-21 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
3784 * term/win.trm (HELP): Got rid of some tabs.
3786 * docs/gnuplot.doc: Fixed some blank-only lines.
3787 (fit control, fit control variables, fit control environment,
3788 splot overview): Get rid of _ between words. Suggested by Dan
3791 2006-05-20 Timothee Lecomte <timothee.lecomte@ens.fr>
3793 * src/color.h (colorspec_t) [EXTENDED_COLOR_SPECS]: Declare the
3794 type before using it (fixes the compilation of linux.trm and
3797 2006-05-20 Ethan A Merritt <merritt@u.washington.edu>
3799 * src/gplt_x11.c term/x11.trm: Allow user control of solid/dashed line
3800 setting via the usual three mechanisms
3801 new X resource gnuplot*dashed: on
3802 from command line `gnuplot -dashed ...`
3803 from gnuplot command `set term x11 {dashed|solid} ...`
3805 * term/x11.trm: Bugfix: persist/raise/dashed terminal settings should
3806 not be conditional on mouse support.
3808 2006-05-20 Ethan A Merritt <merritt@u.washington.edu>
3810 * share/Gnuplot.app-defaults share/Makefile.am:
3811 New X resources file, intended for installation in the system's
3812 default location for X resources.
3815 2006-05-19 Timothee Lecomte <timothee.lecomte@ens.fr>
3817 * src/wxterminal/gp_cairo.c (gp_cairo_draw_enhanced_text):
3818 Remove unappropriate comments about enhanced_max_height.
3819 (gp_cairo_end_polygon): Remove useless comment.
3820 (gp_cairo_convert_symbol_to_unicode): Change C++-style
3821 comments to C style /* ... */.
3822 (gp_cairo_initialize_plot): To avoid overflows, change
3823 strcpy() to strncpy(), strcat() to strncat() and sprintf() to
3825 (gp_cairo_set_font): Likewise.
3826 (gp_cairo_add_shape): Likewise.
3827 (gp_cairo_enhanced_flush): Likewise.
3828 (gp_cairo_enhanced_open): Likewise.
3829 (gp_cairo_draw_enhanced_text): Likewise.
3831 * src/wxterminal/wxt_gui.cpp (wxt_set_font): Likewise.
3833 * term/wxt.trm (wxt_options): Likewise.
3835 2006-05-18 Timothee Lecomte <timothee.lecomte@ens.fr>
3837 * src/Makefile.am (AUTOMAKE_OPTIONS): Remove 'subdir-objects',
3840 * configure.in (enable_wxwidgets): Remove test AM_PROG_CC_C_O,
3841 not needed now that 'subdir-objects' is not used.
3843 * src/wxterminal/wxt_gui.cpp (wxt_waitforinput) [_Windows]:
3844 Rework event processing to avoid code duplication and handle
3845 more cases (pause, etc.).
3846 (wxt_waitforinput_pause) [_Windows]: Removed.
3847 (wxt_terminal_events) [_Windows]: New routine to process
3848 pending events from the wxWidgets terminal when it is selected
3849 and initialized. Its return code is used to stop a pause.
3850 (wxt_set_font): Use reasonable defaults for font name ("Sans")
3851 and size (10) instead of the wxWidgets system settings. It
3852 avoids to choose the inappropriate Courier font on Windows,
3853 where it is used by the console-like window.
3855 * src/wxterminal/wxt_term.h (wxt_waitforinput_pause):
3858 * src/wxterminal/wxt_plot.h (wxt_terminal_events):
3861 * src/win/wpause.c (PauseBox) [WXWIDGETS]: Use
3862 wxt_terminal_events().
3864 * src/win/wtext.c (TextGetCh) [WXWIDGETS]: Likewise.
3866 * term/wxt.trm (help): Change the help text according to the
3867 change in the default font name and font size.
3869 2006-05-18 Lars Hecking <lhecking@users.sourceforge.net>
3871 * docs/Makefile.in: Add titlepag.ipf to EXTRA_DIST.
3873 * docs/gnuplot.texi: Regenerated.
3875 2006-05-15 Timothee Lecomte <timothee.lecomte@ens.fr>
3877 * src/wxterminal/bitmaps/xpm/cross.xpm:
3878 * src/wxterminal/bitmaps/xpm/right.xpm:
3879 * src/wxterminal/bitmaps/xpm/rotate.xpm:
3880 * src/wxterminal/bitmaps/xpm/size.xpm:
3881 Cross-platform cursors.
3883 * src/wxterminal/wxt_gui.h
3884 (wxt_cursor_cross, wxt_cursor_right, wxt_cursor_rotate,
3885 wxt_cursor_size): Cursors declarations.
3886 (wxtApp::LoadCursor): Routine to initialize a cursor.
3888 * src/wxterminal/wxt_gui.cpp
3889 (wxtApp::LoadCursor): Likewise.
3890 (wxtApp::OnInit, wxt_set_cursor): Use new cursors.
3891 (wxt_reset): Clear the events list when receiving ctrl-c.
3892 (wxtPanel::DrawToDC): Fix zoom strings on Windows.
3894 * src/wxterminal/gp_cairo.c (gp_cairo_linetype2color): Fix modulo
3895 operator to use the whole nine colors.
3896 (gp_cairo_draw_point): Fix position of triangles with the
3897 oversampling. Close the path for the filled triangle.
3899 * configure.in (CPPFLAGS): Remove useless gtk and wxWidgets flags
3902 2006-05-15 Bastian Maerkisch <bmaerkisch@web.de>
3904 * config/makefile.os2: Define GIF_ANIMATION and HAVE_PDFLIB_H.
3906 * config/config.os2: Sync to config.h created by `configure`. Define
3907 EAM_OBJECTS, GP_STRING_VARS = 2, HIDDEN3D_VAR_PTSIZE.
3909 * src/os2/gclient.c (DisplayClientWndProc): Filter out WM_MOUSEMOVE
3910 events when the mouse hasn't been really moved. This eliminates
3911 excessive calls to gp_exec_event(GE_motion, ...) and subsequent
3912 unnecessary redraws of the plot.
3914 2006-05-13 Bastian Maerkisch <bmaerkisch@web.de>
3916 * config/makefile.nt: Make sure that the same (basic) compiler options
3917 are used for compiling wgnuplot and pgnuplot. This is necessary since
3918 they both contain version.c.
3920 * src/stdfn.h src/win/winmain.h src/win/wpause.c: Implementation of a
3921 non-blocking sleep function (gnuplot's 'pause' command) for windows.
3923 * term/win.trm (WIN_options, help text):
3924 Accept font request strings of the form
3925 set term win ... font "<fontface>,<fontsize>"
3927 set term win ... "<fontface>" <fontsize>
3928 remains valid as well. Update documentation.
3930 * src/os2/4allterm.cmd: Fix broken argument parsing. Convert end of line
3931 to CR/LF pairs. This is a must for the script to be readable by the OS/2
3934 * docs/doc2ipf.c docs/titlepag.ipf:
3935 - Increase depth of table of contents from 5 to 6. This fixes
3936 "unknown reference" errors during compilation.
3937 - Only replace '.' in first column by ipf tag, it's not needed
3939 - Add an index: interactive help ('?') and explicit index entries ('=')
3941 - Table layout improvements:
3942 - omit table frame and horizontal lines
3943 - add additional horizontal spacing around table entries (1 char)
3944 - omit horizontal rules '_' (troff command)
3945 - entries are only interpreted as troff commands if they start with
3946 '.' and do not contain a table separator
3947 - try to filter out ipf tags when calculating column widths
3948 - always assume troff header at beginning of table. This fixes
3949 coloring of table headers, which has been broken since 17 Jun 1998
3950 - Change handling of paragraphs and verbatim sections: successive empty
3951 lines only yield one new paragraph :p. This eliminates large empty
3952 spaces (especially in front of tables).
3953 - End sections with an empty paragraph instead of starting with an empty
3954 paragraph. Eliminates empty space at beginning of section and (still)
3955 ensures non-empty sections.
3956 - Optionally add additional reference panels to make navigation with
3957 IBM's online viewer easier. Controlled by #define IPF_MENU_SECTIONS.
3958 - Add a title page (new file titlepag.ipf).
3960 2006-05-12 Ethan A Merritt <merritt@u.washington.edu>
3962 * term/gd.trm (PNG_point): Bugfix: Draw filled circles with
3963 gdImageFilledArc rather than a 2-stage bound-and-fill.
3965 * src/graph3d.c (draw_3d_graphbox): Bugfix: Only draw vertical lines
3966 from base corners to surface if there really _is_ a surface.
3967 Having pm3d in surface mode is not sufficient.
3969 * demo/contours.dem: Where the above fix removes a vertical line along
3970 z, remove the z axis tics also. Add a single-color contour demo.
3972 * src/wxterminal/gp_cairo.c: Remove unused variables.
3974 2006-05-04 Timothee Lecomte <timothee.lecomte@ens.fr>
3976 * configure.in (AC_PROG_CXX): Redefine AC_MSG_ERROR for
3977 AC_PROG_CXX, to prevent possible fatal errors in future autoconf
3979 (WX_OBJ): Remove definition, let automake handle it.
3981 * src/Makefile.am (BUILD_WXWIDGETS): Simplify conditional
3982 compilation of the wxWidgets terminal, using automake
3983 conditionals instead of gnuplot_DEPENDENCIES and gnuplot_LDADD.
3985 2006-05-01 Timothee Lecomte <timothee.lecomte@ens.fr>
3987 * configure.in (AC_PROG_CXX): Check for C++ unconditionally,
3988 and workaround harmful autoconf settings if no compiler is found.
3989 (PANGO): Raise minimum version to 1.10.
3991 * term.c (init_terminal): Make wxt the default terminal if it
3992 is available even if X11 is not defined.
3994 2006-04-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
3996 * config/makefile.mgw (DESTDIR): MSYS-ify the drive letter.
3997 (GNUSORT): Use Unix-ish path to MSYS port of GNU sort.
3998 (all): Refer to default target instead of copying all its entries.
3999 (default): Remove config.h dependency.
4000 ($(OBJS) $(WINOBJS) dbinary.$(O)): Add rule that they depend on
4002 ($(M)bf_test.exe): Chdir to $(M), not $(D).
4003 (dbinary.$(O)): Input file is $<, not $^.
4004 (install) [WXT]: Move WX-specific installation rules here.
4006 * term/win.trm (WIN_enhanced_flush): Removed unused variables rc,
4009 * term/pslatex.trm (PSTEX_common_init): Avoid warning by making
4010 compile-time test an #if rather than an if.
4012 * config/makefile.mgw: Change this to expect MSYS tools to be used
4013 instead of the older native MINGW32 ports. Necessitates some
4014 workarounds for MSYS quirks.
4015 (HCWPATH): Uncomment one definition, provide a usable default,
4017 (pgnuplot.exe): Needs -HAVE_STDBOOL_H to avoid a warning.
4018 ($(HELPFILE)): Use `-' instead of `/' for $(HCW) options, to avoid
4019 MSYS translating them to drive letters.
4020 (doc2rtf.exe, doc2tex): Strip trailing `/' off macros holding
4021 `../docs/' and `../term/' --- MSYS/MINGW32 gets confused by it.
4023 2006-04-29 Ethan A Merritt <merritt@u.washington.edu>
4025 * term/wxt.trm (wxt_options): Fix improper malloc for font name.
4027 2006-04-29 Timothee Lecomte <timothee.lecomte@ens.fr>
4029 * configure.in: C++, wxWidgets, cairo and pango configuration
4032 * config/makefile.mgw: Likewise.
4034 * src/command.c (raise_lower_command): Raise and lower commands
4035 for the wxWidgets terminal.
4037 * src/command.h : Likewise.
4039 * src/Makefile.am : wxWidgets terminal conditional compilation.
4041 * src/plot.c (main): wxWidgets terminal hook on exit to handle
4042 the 'persist' behaviour.
4044 * src/term.c (init_terminal): Make the wxWidgets terminal
4045 the default on Windows and X11.
4047 * src/term.h: Include the wxWidgets terminal.
4049 * src/win/wgnuplot.rc: Include wxWidgets ressources file.
4051 * src/win/wpause.c (PauseBox): Process events from the wxWidgets
4052 terminal when in pause.
4054 * src/wxterminal/bitmaps/png/autoscale.png
4055 * src/wxterminal/bitmaps/png/clipboard.png
4056 * src/wxterminal/bitmaps/png/config.png
4057 * src/wxterminal/bitmaps/png/grid.png
4058 * src/wxterminal/bitmaps/png/help.png
4059 * src/wxterminal/bitmaps/png/nextzoom.png
4060 * src/wxterminal/bitmaps/png/previouszoom.png
4061 * src/wxterminal/bitmaps/png/replot.png:
4062 PNG icons for the wxWidgets toolbar.
4064 * src/wxterminal/bitmaps/xpm/icon16x16.xpm
4065 * src/wxterminal/bitmaps/xpm/icon32x32.xpm
4066 * src/wxterminal/bitmaps/xpm/icon64x64.xpm:
4067 XPM icons for the wxWidgets window icon.
4069 * src/wxterminal/bitmaps/xpm/notfound.xpm:
4070 XPM icon for the wxWidgets toolbar.
4072 * src/wxterminal/gp_cairo.c
4073 * src/wxterminal/gp_cairo.h
4074 * src/wxterminal/gp_cairo_term.h:
4075 Generic routines to render a plot to a cairo surface.
4077 * src/wxterminal/wxt_gui.cpp
4078 * src/wxterlinal/wxt_gui.h
4079 * src/wxterminal/wxt_plot.h
4080 * src/wxterminal/wxt_term.h:
4081 Graphical user interface based on wxWidgets.
4084 Terminal hooks between term.c and the wxWidgets and cairo
4087 2006-04-28 Timothee Lecomte <timothee.lecomte@ens.fr>
4089 * src/gplot_x11.c (UNSET, no, yes): Remove enum declaration.
4092 (enhanced_recursion, enh_err_check, do_enh_writec):
4093 Remove static declarations.
4094 (enhanced_text, enhanced_cur_text, enhanced_fontscale)
4095 (enhanced_escape_format, enhanced_min_height)
4096 (enhanced_max_height, ignore_enhanced_text):
4097 Remove static declarations.
4098 (UNSET, no, yes): Remove enum declaration.
4100 * src/term_api.h: Declare here the above variables and functions
4101 related to enhanced text support. Variables are declared extern.
4102 (UNSET, no, yes): Declare enum.
4104 * src/readline.c (msdos_getch) [_Windows && USE_MOUSE]:
4105 Call term->waitforinput() when appropriate, so that the wxWidgets
4106 terminal can process events.
4108 2006-04-27 Timothee Lecomte <timothee.lecomte@ens.fr>
4110 * configure.in src/Makefile.am: Change PKG_MAJOR to
4111 VERSION_MAJOR to avoid a conflict with pkg-config macros.
4112 They will be used with cairo, pango, and gtk+ for the wxWidgets
4115 2006-04-27 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
4117 * src/plot2d.c (get_data): Initialize further elements of df_data
4118 depending on plot style, so datafile module can parse absolute
4119 time/data for xlow etc. Similar fix for handling 'set ydata time;
4122 * src/plot3d.c (eval_3dplots): Fix for 'set zdata time; plot "-" u
4123 2'. Replicate realloc size fix from get_data (--> 2006-03-28)
4126 2006-04-26 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4128 * docs/gnuplot.doc (fit control environment): Fix mention of
4129 command 'set fit logfile'.
4131 2006-04-25 James R. Van Zandt <jrv@vanzandt.comcast.net>
4133 * term/cgm.trm (CGM_filled_polygon): Allow filled polygons with up
4134 to 8190 vertices (was only 50). Also, allocate the
4135 polygon/polyline array from the heap, so it only takes space if
4136 the CGM terminal is used.
4138 * term/cgm.trm (CGM_set_color): access colorspec->value only
4139 for type=TC_FRAC when it is defined.
4141 2006-04-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4143 * src/win/wgnuplot.hpj (COMPRESS): New option, enables compression
4144 of the generated .hlp file.
4145 (LCID): New option, fixed the language of generated help files to
4146 English. Hopefully this will avoid incompatibilities like the one
4147 observed with the first binary release of 4.0 for Win32.
4149 2006-04-24 Daniel Sebald <daniel.sebald@ieee.org>
4151 * src/graphics.c (plot_image_or_update_axes) config/config.cyg
4152 config/config.mgw config/config.nt config/config.os2 configure.in:
4153 Removed all use of WITH_IMAGE_VERIFY_ALL_PIXEL_LOCATIONS and any
4154 code associated with verifying pixel locations in the grid.
4156 2006-04-19 Ethan A Merritt <merritt@u.washington.edu>
4158 * term/post.trm (PS_set_font): Do not write font change commands
4159 into the PostScript output stream of the TeX terminal variants
4160 (epslatex, pstex, pslatex). All font handling is done via the TeX
4161 output stream. Bug #1472260
4163 * demo/html/Makefile demo/html/index.save
4164 demo/html/gnuplot_demo.css: Update html display of gnuplot demos.
4166 2006-04-18 Ethan A Merritt <merritt@u.washington.edu>
4168 * src/graphics.c (plot_c_bars) src/plot2d.c (eval_plots): Allow
4169 user to control the width of whiskerbars on candlestick plots.
4170 plot <foo> with candlesticks {whiskerbars {<width>}}
4172 * demo/utf8.dem: Provide a demo for use in testing UTF-8 support
4173 by gnuplot terminals. This demo will only produce reasonable
4174 output on a terminal that supports UTF-8 and a current UTF-8
4175 encoded font with the relevant character maps.
4177 2006-04-17 Ethan A Merritt <merritt@u.washington.edu>
4179 * src/color.h: Add comments to document the meaning of TC_* flag
4182 2006-04-16 Ethan A Merritt <merritt@u.washington.edu>
4184 * term/aquaterm.trm: Correct typos in help text.
4186 * src/set.c (set_object): Fix segfault on incomplete command
4189 * src/term.c (init_terminal): Keep initial terminal setting in
4190 GNUTERM even if it did not actually come from environmental
4193 2006-04-14 Ethan A Merritt <merritt@u.washington.edu>
4195 * src/term.c (change_term init_term): Save value of GNUTERM into a
4196 user-defined variable on entry. Use only first word of GNUTERM
4197 when calling change_term. This allows GNUTERM to contain extended
4198 terminal specs, e.g. setenv GNUTERM "png truecolor transparent".
4200 2006-04-12 James R. Van Zandt <jrv@debian.org>
4202 * term/cgm.trm (CGM_point): Update cgm_current.edge_visibility
4203 before cgm_current.edge_color (was displaying some point symbols
4204 with incorrect edge colors).
4206 2006-04-10 Ethan A Merritt <merritt@u.washington.edu>
4208 * src/graph3d.c (draw_3d_graphbox): Fix bug introduced when adding
4209 newpath/closepath around the border of 3D plots with 'set view map'.
4210 The top border was not getting drawn, and the individual border
4211 components were not being considered separately.
4212 Also, when in 'set view map' mode, honor 'set border {front|back}'.
4214 * src/graphics.c (plot_border) src/gadgets.h: Similar bugfix in 2D.
4216 * src/misc.c (lp_parse): Don't fall into a recursion trap in the
4217 case that 'set style incr user' and 'set style line <foo> lt <baz>'.
4218 This should set the linetype of <foo> to <baz> even if <baz> itself
4219 has been assigned as another line style.
4221 2006-04-08 Ethan A Merritt <merritt@u.washington.edu>
4223 * src/standard.c (f_tanh): Fix a two-fold error in bounds checking for
4224 tanh(). Bug #1452627
4226 2006-04-08 Bastian Maerkisch <bmaerkisch@web.de>
4228 * src/win/pgnuplot.c: Patch for SF bug [1232950] "-persist option does
4229 not work in Version 4.0.0 (Windows)". Omit sending `exit` from pgnuplot
4230 to wgnuplot when `-persist` is given on command line.
4232 2006-04-08 Daniel Sebald <daniel.sebald@ieee.org>
4234 * src/set.c (set_palette_file) docs/gnuplot.doc: Binary palette files
4235 are supported as well. Example:
4236 set palette file "palette.bin" binary record=64 using 1:2:3
4238 2006-04-08 Bastian Maerkisch <bmaerkisch@web.de>
4240 * config/config.os2: Define more features.
4242 * config/makefile.os2:
4243 - add a list of required/recommended tools and libraries,
4244 - make use of pre-built version of libgd from hobbes.nmsu.edu,
4245 - change requirements for newer versions of PDFlib,
4246 - replace shell script to create allterm.h by 4allterm.cmd in Rexx.
4248 * src/os2/4allterm.cmd: New Rexx script to create allterm.h, much faster
4249 than previous code and does not require the unix tool chain to be
4252 2006-04-07 laboratoryman <laboratoryman@users.sourceforge.net>
4254 * src/term.c (test_term): No terminal currently implements any head
4255 fill style (curr_arrow_headfilled) other than 0/1/2. So don't use 3 as
4258 2006-04-05 Ethan A Merritt <merritt@u.washington.edu>
4260 * term/svg.trm: New line-join terminal option {rounded|butt},
4261 with support for smooth joining of closed polygons via the recently
4262 added newpath()/closepath() mechanism.
4264 * src/gadgets.c (draw_clip_arrow): Provide a routine in the core
4265 code that clips arrow head/tail to the canvas boundaries. This means
4266 we don't have to do the clipping in do_arrow(), which has been messy.
4268 * src/graph3d.c (plot_arrows3d plot3d_vectors)
4269 src/graphics.c (place_arrows do_key_sample get_arrow)
4270 Draw arrows using new routine draw_clip_arrow.
4271 Addresses bug #1348015 and others.
4273 * src/term.c (do_arrow): Add a note that the clipping here is now
4274 redundant, and can be removed. Defer removal to a separate patchset.
4276 2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
4278 * src/plot2d.c (eval_plots): Fix inadvertant breakage due to an
4279 accidentally deleted call to arrow_parse().
4281 2006-04-04 Harald Harders <h.harders@tu-bs.de>
4283 * src/term.c (do_arrow) src/term_api.h docs/gnuplot.doc
4285 * src/graphics.c (get_arrow plot_boxes plot_vectors)
4287 * src/misc.c (arrow_use_properties) src/show.c (show_arrow):
4288 Add an option "backhead" to arrow style that reverses the sense
4289 of the arrow. Modify flags to indicate the forward arrowhead and
4290 the backward arrowhead separately, so "heads" sets both flags.
4293 2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
4295 * src/term_api.h src/term.c (newpath closepath) term/README:
4296 Define a new terminal entry point term->path(foo), and wrapper routines
4297 newpath() == term->path(0); closepath() == term->path(1).
4298 These are needed to ensure smooth line joins at the ends of a closed
4299 path in PostScript-like terminals.
4301 * src/graph3d.c (do_3dplot draw_3d_graphbox)
4302 * src/graphics.c (do_plot plot_boxes plot_cbars do_key_sample)
4303 * src/graphics.c (plot_border) src/color.c (draw_color_smooth_box):
4304 Enclose the vector commands that draw rectangles with a
4305 newpath()...closepath() pair. This guarantees a smooth join for the
4306 plot boundary, the key box, colorbox, boxes, and candlesticks.
4308 2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
4310 * src/gplt_x11.c (gpXLoadQueryFont): When trying to load a multibyte
4311 fontset, treat "missing charsets" as a non-fatal warning. This seems
4312 necessary in order to handle en_US.UTF-8 and similar locales, which
4313 claim to require many exotic but trivial charsets. Normally these are
4314 not needed, so it should not be a fatal error if they are missing.
4317 * term/x11.trm: Increase maximum allowed length of font names.
4319 2006-04-04 Ethan A Merritt <merritt@u.washington.edu>
4321 * misc.c (lp_use_properties lp_parse): In "set style increment user"
4322 mode, an explicit linetype should be interpreted as a call for the
4323 corresponding line style. But if there is none, we should load a
4324 description of the linetype rather than failing to initialize the
4325 lp_style_type at all.
4327 2006-03-28 Lars Hecking <lhecking@users.sourceforge.net>
4329 * docs/gnuplot.texi: Regenerated after recent documentation
4332 * term/Makefile.am.in: Add PostScript directory to EXTRA_DIST. Add
4333 uninstall support. Rename install target to install-data-local
4334 (don't use automake-generated targets in Makefile.am) and add
4337 2006-03-28 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4339 * config/makefile.oww (CPPFLAGS): Added -DEAM_OBJECTS.
4341 * src/plot2d.c (get_data): Avoid small size increments on
4342 reallocation --- at least double, and add another 1000 entries for
4345 2006-03-28 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4347 Revised handling of Windows "app data" and home directory
4348 settings by Bastian Maerkisch.
4350 * src/win/winmain.c: WANT_GET_DLLVERSION hardcoded active.
4351 (CSIDL_APPDATA): Provide fallback definition.
4352 (ShutDown): Removed ancient cruft.
4353 (appdata_directory): New function. Dynamically attach to
4354 shell32.dll and ask it for the "application data" directory.
4355 (WinMain): Have get_user_env() take care of finding $HOME.
4356 INIFILE_IN_APPDATA hardcoded.
4358 * src/win/wcommon.h (INIFILE_IN_APPDATA, WANT_GETDLLVERSION):
4359 Definitions removed, hardcoded active now.
4360 (appdata_directory): Added prototype.
4362 * src/plot.c: Added #includes of win/wgnuplib.h, win/wcommon.h.
4363 (get_user_env) [WIN32]: Call helper routine to find Windows'
4364 "application data" directory.
4366 2006-03-27 Ethan A Merritt <merritt@u.washington.edu>
4368 * src/plot2d.c (cp_alloc) src/plot3d.c (sp_alloc): Initialize the
4369 line style, arrow style, and fill style fields of each new plot to
4370 something reasonable.
4372 2006-03-26 Ethan A Merritt <merritt@u.washington.edu>
4374 * NEWS: List various new features added since last October.
4376 * src/gplt_x11.c: Store text rotation angle internally as a double.
4378 2006-03-26 Ethan A Merritt <merritt@u.washington.edu>
4380 SourceForge patchset #1143563 "Place arbitrary objects in plots".
4381 This patchset introduces a general infrastructure for placing
4382 individual geometric objects, similar to "set label" and "set arrow".
4383 However the only objects implemented at this point are rectangles.
4385 set object <tag> rectangle
4386 {from <position> {to|rto} <position>
4387 | center <position> size <w>,<h> | at <position> size <w>,<h>}
4388 {front|back|behind} {fc|fillcolor <colorspec>} {fs <fillstyle>}
4389 {default} {lw|linewidth <width>}
4391 set style rectangle {front|back} {fillcolor <colorspec>}
4392 {fs <fillstyle>} {lw|linewidth <lw>}
4394 * configure.in: Configuration option: ./configure --enable-objects
4395 Conditional compilation flag EAM_OBJECTS
4397 * demo/rectangle.dem docs/gnuplot.doc
4399 * src/gadgets.h src/gadgets.c src/tables.h src/tables.c:
4402 * src/graph3d.c (do_3dplot) src/graphics.c (place_rectangles do_plot)
4403 src/graphics.h: Shared routine to place rectangles in 2D and 3D.
4405 * src/save.c (save_rectangle) src/set.c (set_object set_rectangle)
4406 src/unset.c (unset_object delete_object unset_style_rectangle)
4407 src/save.h src/show.c: General bookkeeping for objects.
4409 2006-03-25 Ethan A Merritt <merritt@u.washington.edu>
4411 * src/graphics.c (plot_c_bars): Re-order the lines making up a
4412 candlestick so that line-joining terminals have some chance of
4413 recognizing that the body is a closed rectangle.
4415 * term/PostScript/prologue.ps: Add a shorthand for closepath.
4417 * src/graph3d.c src/graph3d.h: New routine map3d_position_double() will
4418 be used by "set object" code.
4420 * src/color.c (draw_color_smooth_box): Use new routine
4421 map3d_position_double to avoid a mismatch of parameter types.
4423 * src/unset.c: Replace "set no<foo>" with "unset <foo>" in comments and
4424 error messages; i.e. make them match current syntax.
4426 2006-03-24 Ethan A Merritt <merritt@u.washington.edu>
4428 * src/datafile.c: Remove vestigial comments about df_timecol[].
4430 2006-03-24 Ethan A Merritt <merritt@u.washington.edu>
4432 * configure.in term/Makefile.am.in term/PostScript/*.ps
4433 term/post.trm (PS_common_init PS_dump_prologue_file):
4435 Install and maintain PostScript prologue and character encoding files
4436 in a separate directory, external to the gnuplot executable. This
4437 removes a large chunk of text from the postscript driver, and allows
4438 local customization, editing, or patching of the postscript
4439 configuration. The directory in which these files are stored is taken
4440 from config.h: #define GNUPLOT_PS_DIR
4441 but may be replaced at runtime by an environmental variable of the same
4442 name, or by a "set loadpath" command inside gnuplot.
4443 This change should result in no change to the postscript files output
4446 2006-03-24 Ethan A Merritt <merritt@u.washington.edu>
4448 * src/datafile.h src/datafile.c: Allow an input field expected to be
4449 a time format to be in quotes. Previously anything in quotes was
4450 assumed to be invalid as a numerical value.
4452 2006-03-23 Ethan A Merritt <merritt@u.washington.edu>
4454 * docs/gnuplot.doc: New option "set style increment {user|default}"
4456 By default, successive plots within the same graph will use successive
4457 linetypes from the default set for the current terminal type.
4458 However, choosing the "user" option allows you to step through
4459 user-defined linestyles rather than through the default line types.
4461 * src/gadgets.c src/gadgets.h: Global flag TBOOLEAN prefer_line_styles.
4463 * src/save.c src/set.c src/show.c src/tables.c src/tables.h:
4464 Save/set/show preference for line styles rather than linetypes.
4466 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots):
4467 If (prefer_lines_styles) then autoincrement successive plots by line
4468 style rather than linetype.
4470 * src/misc.c: Missing line style is non-fatal error.
4472 2006-03-23 Ethan A Merritt <merritt@u.washington.edu>
4474 * src/misc.c (lp_parse): Allow "bgnd" as shorthand for "lt -3".
4476 2006-03-23 Daniel Sebald <daniel.sebald@ieee.org>
4478 * demo/pm3dcolors.dem: Make one example more happy.
4480 2006-03-22 Ethan A Merritt <merritt@u.washington.edu>
4482 * src/unset.c (unset_axislabel): Fix memory leak from failure to
4485 2006-03-22 Timothee Lecomte <timothee.lecomte@ens.fr>
4487 * src/gplt_x11.c (handle_selection_event): Fix typo in debug code.
4489 2006-03-19 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4491 * src/graphics.c (boundary): Avoid strchr() on NULL x axis label
4494 2006-03-18 Ethan A Merritt <merritt@u.washington.edu>
4496 Daniel Sebald has pointed out that when the same plot is being redrawn
4497 repeatedly, for instance during interactive rotation of 3D plots, the
4498 process is noticibly slowed by resending the color palette on each
4499 refresh. The following set of changes insures that the palette is only
4500 sent if something has changed.
4502 * src/color.c (make_palette): Do not call term->make_palette() unless
4503 either (a) the palette has changed, (b) the terminal has changed, or
4504 (c) the output device has changed. New routine invalidate_palette()
4505 is available to signal that one of these conditions has occurred.
4507 * src/set.c (set_output set_palette set_palette_defined):
4508 Call invalidate_palette(). Also fix a memory leak.
4510 * src/term.c (change_term): Call invalidate_palette().
4512 2006-03-17 Daniel Sebald <daniel.sebald@ieee.org>
4514 * src/gplt_x11.c (exec_cmd): Realigned conditional code to allow
4515 compilation with ./configure --with-image --disable-binary-x11-polygon.
4516 Fix conditional test associated whith ./configure --disable-with-image.
4518 2006-03-17 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4520 * src/fit.c (splitpath): Reorder tests avoid possible read of
4521 uninitialized memory.
4523 * src/alloc.c (gp_alloc): Cast to (generic *)
4524 (checked_free): Introduced new local variable to reduce number of
4527 * src/hidden3d.c (build_networks): Initialize lp_style from
4528 lp_properties, regardless of whether the plot supposedly has point
4529 symbols drawn or not. Needed because PM3D drops stuff inside that
4532 2006-03-17 Shigeharu Takeno <shige@iee.niit.ac.jp>
4534 * term/aquaterm.trm: Correction of misprints.
4536 2006-03-16 Ethan A Merritt <merritt@u.washington.edu>
4538 * src/set.c (set_tic_prop): Another bandaid to protect against
4539 int_error() from inside try_to_get_string(). Bug #1434633.
4541 2006-03-15 Ethan A Merritt <merritt@u.washington.edu>
4543 * src/plot3d.c (get_3ddata): Reorder code so that mutually exclusive
4544 conditions are handled in an if/elseif/else construct. No actual change
4545 in behavior, but it quiets valgrind warning messages.
4547 * term/post.trm: Prevent segfault if someone passes off an undefined
4548 variable as an epslatex header. This is a bandaid rather than a true
4549 fix, but it's better than segfaulting. The true problem is that an
4550 int_error() exit from expression parsing bypasses proper cleanup of
4551 storage for string variables, and also fails to return NULL to the
4552 caller. Bug #1434633.
4554 2006-03-15 Daniel Sebald <daniel.sebald@ieee.org>
4556 * src/datafile.c (plot_option_comma_separated): Found by valgrind.
4557 Set an uninitialized tuple value to 0.0.
4559 * src/set.c (parse_histogramstyle): Found by valgrind.
4560 Set an unitialized text label to EMPTY_LABELSTRUCT
4562 2006-03-11 Ethan A Merritt <merritt@u.washington.edu>
4564 * demo/html/index.save demo/html/Makefile: Add animate2 to the list
4565 of webified examples.
4567 2006-03-11 Bastian Maerkisch <bmaerkisch@web.de>
4569 * term/pm.trm src/term_api.h src/mouse.h src/mouse.c src/plot.c
4570 src/set.c src/unset.c: Cleanup of the OS/2 menu stuff communicating
4571 gnuplot -> gnupmdrv. This eliminates some 'extern's in C files and moves
4572 code specific to pm terminal to pm.trm.
4573 1. Remove update_menu_items_PM_terminal() from mouse.c.
4574 2. Rename send_gpPMmenu() in mouse.c to PM_set_gpPMmenu() and move the
4575 actual communication with gnupmdrv to new routine
4576 PM_update_menu_items() in pm.trm.
4577 PM_set_gpPMmenu() now only updates the gpPMmenu struct.
4578 3. Replace all calls to update_menu_items_PM_terminal() with calls to
4579 PM_update_menu_items().
4580 4. Removed multiple definitions of PM_intc_cleanup() in plot.c and
4581 pm.trm to term_api.h.
4583 2006-03-11 Ethan A Merritt <merritt@u.washington.edu>
4585 * src/datafile.c (df_open): If a requested input data file is missing,
4586 issue a warning and continue. The old behaviour was to issue an error
4587 and bail to the command line. df_open() now returns a negative number
4588 if the requested file cannot be opened. Callers must test for error
4591 * src/plot2d.c (eval_plots): If a requested file is missing or empty,
4592 create an empty plot structure for it, but plot other functions or
4593 datafiles as usual. May not work for some combinations of missing
4596 * src/plot3d.c (eval_3dplots): Treat a missing input file the same way
4597 as an input file with no usable data points. This is not the same
4598 as skipping it cleanly as in the 2D case. 3D should be brought in line
4599 with 2D, but it will require revision of the data structure handling.
4601 * src/fit.c (fit_command): Give an error message if an input data file
4602 is missing or not readable.
4604 * src/graphics.c (do_plot): Re-indent code section dealing with
4607 2006-03-11 Ethan A Merritt <merritt@u.washington.edu>
4609 * src/plot2d.c (cp_alloc) src/plot3d.c (sp_alloc): Our plot structures
4610 have gained additional fields over the years, but not all of them were
4611 being initialized on allocation. Switch to zeroing the entire structure
4612 on allocation, then filling in the small number of non-zero fields.
4613 Fixes rare segfault found while debugging "skip missing file" code due
4614 to use of an uninitialized plot->p_count field.
4616 2006-03-10 Petr Mikulik <mikulik@physics.muni.cz>
4618 * src/datafile.c (df_open): Shift misplaced call to gp_expand_tilde.
4620 2006-03-06 Bastian Maerkisch <bmaerkisch@web.de>
4622 * src/command.c: #include direct.h if compiling with MSVC.
4624 2006-03-06 Hans-Bernhard Broeker <broeker@physik.rwth-achen.de>
4626 * docs/titlepag.tex: The previous method of detecting pdflatex
4627 vs. normal latex no longer works (some clever guys decided that
4628 they should use pdflatex to make DVI files...). Give up trying to
4629 sort out that mess. Just assume that hyperref knows this on its
4632 * src/syscfg.h (OS): Provide a fallback definition to avoid using
4634 (GP_EXCEPTION_NAME) [__WATCOMC__]: Define.
4636 * config/makefile.oww: Some changes to make better use of Watcom's
4639 * src/win/wgraph.c (drawgraph): Add missing break.
4641 * term/win.trm (Win_Opts): Change abbreviations of option
4643 (WIN_Font, WIN_Fontsize): Initialize to sensible defaults.
4644 (WIN_enhanced_flush): Remove unused local variable mode.
4646 2006-03-04 Ethan A Merritt <merritt@u.washington.edu>
4648 * term/cgm.trm (CGM_options) term/emf.trm (EMF_options)
4649 term/pdf.trm (PDF_options) term/post.trm (PS_OPTIONS):
4650 Accept font request strings of the form
4651 set term <foo> ... font "<fontface>,<fontsize>"
4652 Whatever previous syntax each terminal used remains valid as well.
4654 2006-03-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4656 Support for 'with image' plots in Windows, from Bastian Maerkisch.
4658 * term/win.trm (WIN_image): New function. An edited copy of
4660 (TERM_ENTRY): Add entry for WIN_image.
4662 * src/win/wgraph.c (GraphOp, GraphOpSize): Moved body of previous
4663 GraphOp function to GraphOpSize, which has additional argument.
4664 GraphOp replaced by a call to the new function.
4665 (drawgraph): Handle new opcode W_image.
4667 * src/win/wgnuplib.h (W_image): New wgraph operation code.
4668 (GraphOpSize): Added prototype.
4670 2006-03-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4672 Bastian Maerkisch's enhanced text mode patch for Windows:
4674 * src/win/wgnuplib.h (W_font): New operation code macro.
4675 (struct tagGW): New members deffontname, deffontsize describing
4677 (GraphChangeFont, GraphGetTextLength, GraphGetFontScaling): Added
4680 * src/win/wgraph.c (SelFont): Write font to graphwin struct.
4681 (drawgraph): Use TA_BASELINE instead of TA_BOTTOM text alignment.
4682 Add handling of opcode W_font.
4683 (WriteGraphIni): Write default font instead of current font as
4685 (ReadGraphIni): Read default font from GraphFont= entry.
4686 (GraphChangeFont, GraphGetTextLength): New functions.
4687 (GraphGetFontScaling): New function (#if'ed out).
4689 * term/win.trm (enum WIN_id, WIN_opts): New option {no}enhanced.
4690 (WIN_font, WIN_fontsize, WIN_angle, WIN_x, WIN_y,
4691 WIN_justification): New variables duplicated out of graphwin
4693 (ENHwin_opened_string, ENHwin_show, ENHwin_overprint,
4694 ENHwin_widthflag, ENHwin_sizeonly, ENHwin_base): New variables.
4695 (WIN_options): Pass font name and size on to struct graphwin.
4696 Accept new option {no}enhanced.
4697 (WIN_move, WIN_justify_text, WIN_text_angle): Save arguments to
4699 (WIN_set_font, WIN_enhanced_open, WIN_enhanced_flush,
4700 WIN_enhanced_put_text):
4701 (TERM_ENTRY): Add entries for new functions.
4703 2006-03-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
4705 * config/makefile.cyg (HCWPATH): Look for HCW in the default place
4706 where it installs itself.
4707 ($(OBJS) $(WINOBJS) dbinary.$(O)): Make these depend on config.h.
4708 (default, all): Generate config.h by real dependency.
4709 (show.$(O)): Don't assume .o extension.
4711 * config/config.cyg: No, we don't HAVE_PWD_H.
4713 2006-03-02 Mike Sutton <mws116@usa.com>
4715 * term/cgm.trm (CGM_set_color): Let the CGM driver set color
4716 when colorspec type is TC_LT.
4718 2006-02-28 Ethan A Merritt <merritt@u.washington.edu>
4720 * src/term.c (term_close_output): Fix fatal double-close error
4721 triggered by error return from post.trm at any point where gppsfile
4722 and gpoutfile both point to the same file descriptor.
4724 * term/post.trm: Fix broken linetype definitions loaded by
4725 set term epslatex oldstyle
4727 2006-02-28 Lars Hecking <lhecking@users.sourceforge.net>
4729 * demo/Makefile.am.in: Add *.pdb and *.r3d to EXTRA_DIST generation.
4731 * docs/gnuplot.texi: Regenerated after recent documentation updates.
4733 2006-02-28 Per Persson <persquare@mac.com>
4735 * term/aquaterm.trm: Added encoding support to aqua terminal. Currently
4736 supports iso_latin_1, iso_latin2, and cp1250. Default is iso_latin_1.
4738 2006-02-27 Bastian Maerkisch <bmaerkisch@web.de>
4740 SF patch [1436005] WIN: change sequence of pointstyles
4742 * src/win/wgnuplib.h src/win/wgraph.c: Change the sequence of poinstyle
4743 symbols such that it matches the sequence of terminals like postscript
4746 2006-02-26 Ethan A Merritt <merritt@u.washington.edu>
4748 * demo/html/index.save: Update web site template for 4.1 demos.
4750 * src/set.c(set_decimalsign) src/variable.c(locale_handler)
4751 src/show.c(show_command show_decimalsign show_locale) docs/gnuplot.doc:
4752 Work a little harder to show both the current input and output settings
4753 for decimal point handling (LC_NUMERIC locale setting).
4755 2006-02-25 Ethan A Merritt <merritt@u.washington.edu>
4757 * graph3d.c (do_3dplot): Contour lines are supposed to be in different
4758 colors, but this was only working if the surface itself was drawn in a
4759 simple linetype. Fix contour auto-coloring even for explicit rgb or
4760 other surface-coloring modes.
4762 2006-02-25 Ethan A Merritt <merritt@u.washington.edu>
4764 * src/gadgets.h src/term_api.h: Move line type definitions into
4765 term_api.h, since they exist to request specific terminal behavior.
4766 Remove definition of L_TYPE_NODRAW. It is now superseded by LT_NODRAW.
4768 * src/misc.c (parse_colorspec); Now that LT_BACKGROUND is safe to pass
4769 to all terminal drivers, allow it as a legal linetype (-3) in commands.
4771 2006-02-24 Petr Mikulik <mikulik@physics.muni.cz>
4773 * src/tables.c (set_palette_tbl pm3d_color_names_tbl): Support both
4774 spellings of "gray" and "grey".
4776 2006-02-23 Shigeharu Takeno <shige@iee.niit.ac.jp>
4778 * docs/gnuplot.doc term/post.trm: Correction of misprints.
4780 2006-02-23 Petr Mikulik <mikulik@physics.muni.cz>
4782 * demo/pointsize.dem: Add 'reset' at the end.
4784 2006-02-21 Daniel Sebald <daniel.sebald@ieee.org>
4786 * term/post.trm (PS_encode_image): The computation for the max number
4787 of required bytes for encoding the image didn't take into account that
4788 there is 8 bit alignment (potentially additional 7 bits) at the end
4789 of each image line. The encoded image was written outside memory on
4790 the heap and corrupted when cleared. Fixed, and added an assert()
4791 test, after the fact, to compare encode size against memory size.
4793 2006-02-21 Daniel Sebald <daniel.sebald@ieee.org>
4795 * src/gplt_x11.c (scan_palette_from_buf): The read_input() status
4796 was ignored and consequently when a partial read of the pipe happened
4797 a full line was not removed from pipe. For long palettes garbage
4798 remained in pipe when done and next command was bogus.
4800 * src/gplt_x11.c (read_input_line): A new routine that will check
4801 status of read_input and continue reading if only a partial read.
4802 If there are too many reads, the routine gives warning.
4804 2006-02-21 Daniel Sebald <daniel.sebald@ieee.org>
4806 * src/getcolor.c (interpolate_color_from_gray): The index could go
4807 to one past the end of the array and cause a program crash. This
4808 was fixed with a bisecting routine as suggested by the old comment
4809 nearby, as opposed to the linear search.
4811 2006-02-20 Ethan A Merritt <merritt@u.washington.edu>
4813 * term/imagen.trm (IMAGEN_cvts): Obviously no one uses this driver,
4814 because if they had they would have noticed that it's been trampling
4815 on unallocated memory since version 3.7 times or earlier. Fixed.
4817 * term/metapost.trm (MP_filled_polygon MP_boxfill): solid fill density
4818 parameter was being interpreted incorrectly.

4830 Replace L_TYPE_NODRAW and explicit constants -2, and -1 with
4831 LT_NODRAW, LT_BLACK, and LT_AXIS respectively.
4833 Make sure all drivers check for legal linetype in term->linetype().
4834 Many drivers were not prepared to handle term->linetype(LT_BACKGROUND).
4835 Note that it was unsafe even to call term->linetype(LT_BLACK) or
4836 LT_AXIS on some older drivers (e.g. iris4d).

4840 * src/axis.c src/color.c src/gadgets.h src/graph3d.c src/graphics.c
4841 src/set.c src/show.c: Replace L_TYPE_NODRAW everywhere in core code
4844 * term/post.trm (PS_options): Fix a memory leak and a double-free
4845 in the code handling epslatex epslatex_header option. While there,
4846 update the code to handle string variables.
4849 2006-02-19 Dennis Linse <djlinse37@users.sourceforge.net>
4851 * missing: Add work-around for parsing bug that cannot handle the
4852 "--output=<foof>" option to makeinfo. See also the change below,
4853 which removes gnuplot.info from the default make target.
4856 2006-02-19 Ethan A Merritt <merritt@u.washington.edu>
4858 * term/gd.trm (image_do_crop): Move libgd version 2 dependency
4859 inside conditional code segment. Bug #1434658.
4861 * docs/Makefile.in: Add an empty target for "install-exec", and
4862 remove gnuplot.info from the target "all". These changes are needed
4863 in order for either a default "make" or "make install-exec" to
4864 succeed on a system without emacs or makeinfo.
4866 Thanks to Dennis Linse <djlinse37@users.sourceforge.net>
4868 Note: an alternative is not to use the .../missing script for
4869 makeinfo, or somehow make the fact that it's missing a non-fatal

4874 SF patch [1432890] Win: rotated text at arbitrary angles
4876 * src/win/wgnuplib.h src/win/wgraph.c term/win.trm: Rotated text at
4877 arbitrary angles for the windows terminals.
4879 2006-02-16 Bastian Maerkisch <bmaerkisch@web.de>
4881 SF patch [1384525] Small fixes to gd terminals
4883 * term/gd.trm: Fixes for Win32 to allow linking with bgd.dll or static.
4884 - Static linking with gdlib is now possible (again) on windows (NONDLL
4885 is taken into account).
4886 - A new define GD_NEED_LOCAL_FONT_POINTERS is added. When defined
4887 gd.trm will use local pointers to the fonts built into gdlib. This
4888 is highly recommended by Mr. Boutell on Windows platforms. Currently
4889 it is only activated on Windows when linking to bgd.dll.
4891 2006-02-12 Daniel Sebald <daniel.sebald@ieee.org>
4893 * term/post.trm (PS_encode_image PS_image): Bug fix for the PostScript
4894 image using the five operand form (i.e., no palette). The bug was
4895 that the max colors was not set to 2^N, where N is 1, 2, 4, 8, or 12.
4896 So if the gray scale max was 128 (2^7) the brightness was lower than
4897 it should have been.
4899 2006-02-12 Petr Mikulik <mikulik@physics.muni.cz>
4901 * src/graph3d.c (do_3dplot): Fixed the condition for which the message
4902 of missing blank lines in a datafile for pm3d plot is displayed.
4904 2006-02-11 Timothee Lecomte <timothee.lecomte@ens.fr>
4906 * src/gplt_x11.c (handle_selection_event): Export a timestamp for each
4907 selection request, as per the X11 clipboard handling standard.
4909 2006-02-06 Ethan Merritt <merritt@u.washington.edu>
4911 * docs/gnuplot.doc: Make "set xyplane" description more self-consistent.
4913 2006-02-03 Petr Mikulik <mikulik@physics.muni.cz>
4915 * src/set.c (set_tics set_tic_prop): Draw nomirrored tics correctly for
4916 "reset; unset xtics; set xtics nomirror; splot x" and
4917 "reset; unset tics; set tics nomirror; splot x".
4919 2006-02-03 Ethan Merritt <merritt@u.washington.edu>
4921 * src/graphics.c (plot_c_bars): Clip candlesticks (financebars)
4922 to vertical plot boundaries.
4924 2006-02-02 Ethan Merritt <merritt@u.washington.edu>
4926 * src/gplt_x11.c (handle_selection_event): Clean up yesterday's
4927 code a little, and separate the pixmap request from the mouse
4928 coordinate string request. By making the string request
4929 separately, it seems that klipper now notices it.
4931 2006-02-01 Ethan Merritt <merritt@u.washington.edu>
4933 * src/gplt_x11.c (handle_selection_event): Fix bad interaction
4934 between gnuplot_x11 and X11 clipboard management tool "klipper".
4935 Refuse to export the pixmap and colormap more than once per
4936 plot export. For unknown reasons, klipper continues to ask for
4937 copies of both ad infinitum. Fixes bugs ##1225866 and #1420675.
4939 2006-01-31 Ethan Merritt <merritt@u.washington.edu>
4941 * src/command.c: (VMS) replace MAILBOX with "PLOT$MAILBOX"
4943 * src/set.c (set_timestamp): Use gp_strdup() rather than strdup().
4945 * src/term_api.h: Remove trailing comma from definition of
4948 * src/util.c (existdir): Special case VMS.
4950 With these minor tweaks, the current gnuplot source will compile
4951 and build under VMS using DECC. Not all drivers tested, though.
4953 2006-01-28 Ethan Merritt <merritt@u.washington.edu>
4955 * src/term.c (parse_term_size): New routine intended to be shared
4956 by terminals with "set term <foo> size XX, YY" option. The routine
4957 itself supports size specification in inches, cm, or pixels. The
4958 calling terminal can limit which units are acceptable.
4960 * term/post.trm (term_options): "set term ... size XX, YY" option.
4961 This is intended to replace the older mechanism:
4962 "set size ... ; set term ...". The new code gets the bounding box
4963 right, which the old mechanism does not, and it rationalizes the use
4964 of screen coordinates to match that of other (but not all) terminals.
4966 2006-01-26 Ethan Merritt <merritt@u.washington.edu>
4968 * src/datafile.c (df_read_matrix): Bugfix for "every" option in plot
4969 "matrix ... every *:*:firstpoint:*". If we are explicitly skipping
4970 input columns, it doesn't matter whether they contain legal input or
4971 not. Therefore test index against firstpoint before trying to parse
4974 2005-01-23 Daniel Sebald <daniel.sebald@ieee.org>
4976 * src/graphics.c (plot_image_or_update_axes): Fix for
4977 "plot [from:to] [from:to] ... with image".
4979 2006-01-21 Petr Mikulik <mikulik@physics.muni.cz>
4981 * src/graph3d.c (do_3dplot): The mistake of missing blank lines in a
4982 datafile for pm3d plot is so frequently made that it really deserves
4985 2006-01-19 Ethan Merritt <merritt@u.washington.edu>
4987 * src/color.c src/color.h src/gadgets.c src/gadgets.h: Move color_box
4988 structure and associated definitions from color.* to gadgets.*. This
4989 resolves a circular header dependency if the structure is to be shared
4990 by 2D and 3D code. Add (struct position) entries to color_box structure
4991 to generalize the placement options.
4993 * src/command.c src/command.h src/gadgets.c src/gadgets.h: Move the
4994 related TBOOLEAN flags is_3d_plot and is_cb_plot from command.* to
4997 * src/save.c src/show.c src/set.c src/unset.c: Convert the relevant
4998 routines to manipulate color_box position using new (struct position)
5001 * docs/gnuplot.doc: Document that color_box placement can now be
5002 specified in any of gnuplot's coordinate systems.
5004 2006-01-15 Ethan Merritt <merritt@u.washington.edu>
5006 * docs/gnuplot.doc: Correct various typos and spelling errors.
5008 2006-01-13 Ethan Merritt <merritt@u.washington.edu>
5010 * term/emf.trm: EMF_filled_polygon has the side-effect of
5011 changing the current line color. Force re-evaluation of line
5012 properties the next time a line is drawn.
5014 2006-01-13 Timothee Lecomte <timothee.lecomte@ens.fr>
5016 * demo/rainbow.dem: Do not "unset mouse" inside demo.
5018 2006-01-12 Ethan Merritt <merritt@u.washington.edu>
5020 * term/svg.trm: Avoid improper call to strcpy found by valgrind.
5022 * term/emf.trm: Allow terminal to use LT_BACKGROUND as a line or
5025 * term/xlib.trm (Xlib_reset): Give xlib its own reset function,
5026 because sharing one with x11 can lead to a double-free of the
5027 output file, resulting in a segfault (found by valgrind).
5029 2006-01-11 Ethan Merritt <merritt@u.washington.edu>
5031 * src/plot3d.c (get3d_data): Fix initialization code for 3D plot
5032 style `with vectors`.
5034 2005-01-07 Mike Sutton <mws116@usa.com>
5036 * term/gd.trm: New terminal option {rounded|butt} controls line caps.
5038 * src/color.c (draw_color_smooth_box): In splot in view map mode, have
5039 the colorbox extend the full height of the y axis by default. Placement
5040 in 3D plots is not affected. This was the old (pre-4.0) behaviour.
5042 2005-01-07 Daniel Sebald <daniel.sebald@ieee.org>
5044 * term/gd.trm: Addtional processing of animated gifs to bring
5045 output file into compliance with the Gif89a standard.
5047 * demo/animate2.dem demo/rotate.gnu: New demo of gif animation,
5048 showing transparency. Revised rotation code for both animate
5051 2006-01-07 Ethan Merritt <merritt@u.washington.edu>
5053 * src/term.c (term_end_multiplot): Free title string and clear
5056 2005-01-07 Daniel Sebald <daniel.sebald@ieee.org>
5058 * src/gplt_x11.c (record): Incorrect nesting of parentheses.
5060 2006-01-02 Ethan Merritt <merritt@u.washington.edu>
5062 * term/gd.trm (PNG_options): Change default animation mode to
5063 "nooptimize". Disable optimization if the background is transparent,
5064 as this combination is not handled well by most viewing programs.
5066 2006-01-02 Dennis Linse <djlinse37@yahoo.com>
5068 * term/x11.trm: Remove redundant #include <sys/select.h>
5070 2005-12-30 Ethan Merritt <merritt@u.washington.edu>
5072 * term/gd.trm (PNG_options): Initialize and report animate {nooptimize}
5073 flag in terminal options string.
5075 2005-12-29 Ethan Merritt <merritt@u.washington.edu>
5077 * term/gd.trm term/vgagl.trm: Cleanup (#undef) definition of Y(coord)
5078 before leaving driver code.
5080 * term/pdf.trm: Correct signedness problem in call to PDF_open_image().
5082 * term/svg.trm: Increase the internal resolution of terminal coordinates
5083 by adding a scale factor SVG_SCALE. This fixes the "wavy line" bug seen
5086 2005-12-29 Petr Mikulik <mikulik@physics.muni.cz>
5088 * term/gd.trm: New routine image_do_crop(), extracted from png_text().
5089 Now shared for cropping all png/gif/jpeg images.
5091 2005-12-26 Ethan Merritt <merritt@u.washington.edu>
5093 * src/graph3d.c (place_label3d): Let write_label handle clipping to
5094 the page, rather than duplicating it in place_label3d.
5096 2005-12-21 Ethan Merritt <merritt@u.washington.edu>
5098 * term/gd.trm (PNG_text): Work around unexpected behaviour in libgd,
5099 which does not copy transparent pixels during a copy operation.
5102 2005-12-17 Bastian Maerkisch <bmaerkisch@web.de>
5104 * src/win/wgraph.c (drawgraph): Fixed "splot x with line palette lw 10".
5106 2005-12-17 Petr Mikulik <mikulik@physics.muni.cz>
5108 * src/version.c: Changed value of gnuplot_date[] from a useless
5109 July 2004 day into "December 2005".
5111 * src/mouse.h src/mouse.c: Added new field was_splot_map in structure
5112 t_zoom. It should fix yet another occurence of "set view map; plot x"
5113 and y-axis reversal when zooming by mouse and unzooming by hotkeys.
5115 2005-12-15 Bastian Maerkisch <bmaerkisch@web.de>
5117 * term/win.trm (WIN_set_color) src/win/wgraph.c (drawgraph): Support for
5118 text color via RGB and via linetype color values.
5120 2005-12-14 Bastian Maerkisch <bmaerkisch@web.de>
5122 * config/makefile.nt: Fixes for linking with bgd.dll.
5124 * src/term.c: #include <io.h> for __MSC__.
5126 2005-12-11 Ethan Merritt <merritt@u.washington.edu>
5128 * src/graph3d.c (do_3dplot): Add a BoundingBox structure to describe
5129 the plot boundaries in 'set view map' mode.
5131 2005-12-06 Ethan Merritt <merritt@u.washington.edu>
5133 * src/graph3d.c (do_3dplot) src/graph3d.h src/plot3d.c (eval_3dplots)
5134 src/hidden3d.c (build_networks) docs/gnuplot.doc: Add an option
5135 `with <plotstyle> nohidden3d` that allows you to exclude a particular
5136 plot from the global `set hidden3d` processing.
5138 2005-12-06 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
5140 * src/hidden3d.c (COORD_TO_TREECELL, COORD_TO_BITMASK): Avoid
5141 overflow by undoing effect of surface_scale before mapping to
5143 (store_polygon): Add assert()s to internal macros GET_MIN,
5144 GET_MAX, to catch problems not handled by above changes.
5145 (in_front): Avoid accessing qlist[-1]. Make sure
5146 p_list[] is always filled, even if doing a single-vertex pseudo
5149 2005-12-05 Ethan Merritt <merritt@u.washington.edu>
5151 * src/hidden3d.c (build_networks): Each plot with style LABELPOINTS
5152 contains a linked list of labels. But the first label in this list is
5153 a dummy entry used only as a placeholder for style parameters. The
5154 hidden3d code was incorrectly counting this as an actual label.
5155 Fixes at least some instances of bug #1372464.
5157 2005-12-04 Ethan Merritt <merritt@u.washington.edu>
5159 * src/gadgets.h: Add new internal linetype LT_COLORFROMCOLUMN
5161 * src/graph3d.c (do_3dplot): Remove warning if no surface is visible
5162 in plot with hidden3d set.
5164 * src/hidden3d.c src/util3d.h: Modify struct vertex so that it contains
5165 a pointer (lp_style_type *)lp rather than simply an (int)style. This
5166 allows all the various point properties to be handled in hidden3d mode
5167 except for variable pointsize. Variable pointsize is handled by adding
5168 a new field (struct coordinate *)original. This, however, increases the
5169 size of struct vertex, so it can be configured out under the control of
5170 HIDDEN3D_VAR_PTSIZE.
5172 * demo/pointsize.dem demo/rgb_variable.dem: Update demos to show off
5173 use of 'set hidden3d' for 3D point plots.
5175 * src/graph3d.c src/hidden3d.c: Handle 'splot with vectors' in
5178 * demo/molecule.dem demo/GM1_bonds.r3d demo/GM1_sugar.pdb: New
5179 demo that shows off vector+point plots in hidded3d mode.
5181 2005-12-02 Ethan Merritt <merritt@u.washington.edu>
5183 * src/gplt_x11.c src/gplt_x11.h: Move #include <sys/select.h> from
5184 gplt_x11.c to gplt_x11.h so that x11.trm can see it also.
5187 * term/x11.trm: Remove duplicate #define for constants present in
5190 2005-12-01 Michael Williamson <mwilliamson@users.sourceforge.net>
5192 * src/set.c (set_size): Do not allow size values <= 0.
5194 2005-11-29 Petr Mikulik <mikulik@physics.muni.cz>
5196 * src/mouse.c (apply_zoom): Fix for "set view map; plot x" and y-axis
5197 reversal when mouse zooming.
5199 2005-11-28 Petr Mikulik <mikulik@physics.muni.cz>
5201 * src/datafile.c (df_set_datafile_binary): Give an error message for
5202 'set datafile binary' (without any option).
5204 2005-11-27 Juergen Wieferink <wieferink@freenet.de>
5206 * src/parse.c (const_string_express parse_additive_expression)
5207 src/parse.h src/eval.c (pop_or_convert_from_string) src/eval.h
5208 src/util.c (try_to_get_string) src/internal.c (f_minus)
5209 src/set.c (set_label set_xyzlabel load_tic_user):
5211 Clean up parsing and evaluation of try_to_get_string() by moving the
5212 test against STRING_RESULT_ONLY into the actual parsing code. Now if
5213 a + or - operator is encountered while parsing something that is
5214 supposed to be a string, no further tokens are processed. Before, this
5215 triggered an arithmetic operation on the string that had to be thrown
5218 2005-11-27 Ethan Merritt <merritt@u.washington.edu>
5220 * src/set.c (set_arrow): Rewrite set_arrow() to behave the same as
5221 set_label() and other "set <foo>" routines; attribute changes for any
5222 one arrow are now incremental.
5224 * src/misc.c (arrow_parse) src/plot2d.c src/plot3d.c src/set.c:
5225 Remove 2nd parameter of arrow_parse, since it is no longer used by
5228 * src/axis.c (axis_checked_extend_empty_range) src/plot3d.c:
5229 Suppress warning message "empty z range" when mode is "set view map".
5231 2005-11-27 Petr Mikulik <mikulik@physics.muni.cz>
5233 * demo/pm3d.dem: Change one splot from "with lp palette" to
5234 "with lines palette".
5236 2005-11-26 Ethan Merritt <merritt@u.washington.edu>
5238 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots):
5239 Bugfix: Arrow style used by "with vector" was getting over-written
5240 during subsequent command line parsing.
5242 2005-11-25 Daniel Sebald <daniel.sebald@ieee.org>
5244 * src/datafile.c (avs_filetype_function) docs/gnuplot.doc:
5245 Support AVS image file format.
5247 plot '<convert foo.jpeg avs:-' binary filetype=avs with rgbimage
5249 2005-11-25 Ethan Merritt <merritt@u.washington.edu>
5251 * src/graphics.c (do_plot do_key_sample)
5252 src/graph3d.c (key_sample_line key_sample_point key_sample_point_pm3d):
5253 Clip key to canvas unless TERM_CAN_CLIP flag is set.
5255 * src/set.c (load_tic_user): Allow string variables and string functions
5256 in 'set {xyz}tics ( FOO <foo>, BAR(x) x, "string"."exp" <place> )
5258 * src/datafile.c (plot_option_binary): Fix logic error in binary file
5259 initialization. Initialization was done inside a parsing loop, but the
5260 loop was never entered unless there were additional keywords on the
5261 command line. Bugfix. "set style data rgbimage" now works.
5263 2005-11-25 Petr Mikulik <mikulik@physics.muni.cz>
5265 * term/tgif.trm (TGIF_init): Message "Creator: gnuplot %s patchlevel %s"
5266 instead of (dollar)Header:(dollar) in output file header.
5268 2005-11-24 Ethan Merritt <merritt@u.washington.edu>
5270 * src/gadgets.c (clip_point) src/term.c (do_arrow): If terminal
5271 flag TERM_CAN_CLIP is set, then set canvas clipping description
5274 * src/term_api.h src/term.c: Export on_page() so that it can be
5275 used for clipping tests by other core modules.
5277 * src/gadgets.c (write_label): If a label has an associated point,
5278 clip the point using the same test as was used for the label itself.
5280 2005-11-24 Juergen Wieferink <wieferink@freenet.de>
5282 * src/util.c (parse_sq) src/scanner.c (scanner) docs/gnuplot.doc:
5283 Fixed \' in single-quoted strings.
5285 2005-11-24 Daniel Sebald <daniel.sebald@ieee.org>
5287 * src/gplt_x11.c: Linked list of color maps separate from the linked
5288 list for x11 plots. Bugfix for different color palettes in different
5289 x11 terminal windows and resizing them.
5291 2005-11-18 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
5293 * src/hidden3d.c (build_networks): Fix handling of previousvertex
5294 variable for point-like objects, which don't need it.
5296 2005-11-14 Juergen Wieferink <wieferink@freenet.de>
5298 * src/set.c (set_xyzlabel): Fix parsing error in backwards-compatible
5299 form "set xlabel 'foo' -1,-1".
5301 2005-11-12 Ethan Merritt <merritt@u.washington.edu>
5303 * src/axis.c (gen_tics): Check whether user-specified tic is major
5304 or minor before choosing a line type for the corresponding grid line.
5306 * term/gd.trm (ENHGD_put_text) term/pdf.trm (ENHPDF_put_text):
5307 Fix typos that caused justification to fail for rotated, enhanced
5310 2005-11-11 Harald Harders <h.harders@tu-bs.de>
5312 * src/axis.c (axis_output_tics): Normally the tics are placed to
5313 dodge the border line. If the border line is not drawn, then do
5314 not try to dodge it.
5316 2005-11-11 Ethan Merritt <merritt@u.washington.edu>
5318 * term/metapost.trm: Update driver to support version 4.1 features.
5319 Implement general text rotation.
5320 Add partial density solid fill support for rectangles and polygons,
5321 with pattern fill implemented as incremental density solid fill.
5322 Fix bugs in terminal option font parsing.
5323 Keep track of dash pattern independent of line color
5325 2005-11-09 Ethan Merritt <merritt@u.washington.edu>
5327 * src/term.c (do_arrow): Revert previous patch, since it seems
5328 the bad effects outweigh the good.
5330 2005-11-08 Ethan Merritt <merritt@u.washington.edu>
5332 * src/term.c (do_arrow): Add a work-around for broken behaviour
5333 by the postscript terminal. post.trm does not correctly report
5334 the current canvas size, so arrows cannot be clipped against the
5335 canvas boundaries if the current terminal is post.trm. The proper
5336 fix is probably in post.trm itself, but it potentially affects
5337 many aspects of plot layout so I am reluctant to make the change
5340 2005-11-01 Ethan Merritt <merritt@u.washington.edu>
5342 * src/plot3d.c (eval_3dplots): Fix logic bug in vector style
5343 initialization. Replicate vector line style properties stored
5344 in arrow_properties into plot's main lp_properties.
5346 2005-10-31 Harald Harders <h.harders@tu-bs.de>
5348 * term/post.trm (PS_options): Add flags to track whether terminal
5349 options have been set; issue error on attempt set option twice.
5351 2005-10-26 Petr Mikulik <mikulik@physics.muni.cz>
5353 * docs/gnuplot.doc: Updated 'help matrix' and 'help matrix ascii'.
5355 2005-10-23 Ethan Merritt <merritt@u.washington.edu>
5357 * src/datafile.c (adjust_binary_use_spec): Interpret the command
5358 "plot <foo> matrix" as equivalent to "plot <foo> matrix using 1:3".
5360 2005-10-22 Harald Harders <h.harders@tu-bs.de>
5362 * term/pslatex.trm (EPSLATEX_set_color): Fix bug in setting
5363 pure black or white via a gray value.
5365 2005-10-22 Ethan Merritt <merritt@u.washington.edu>
5367 * src/datafile.c (df_open): Fix [very] long-standing bug
5368 that caused only the first 3 columns of ascii matrix data to
5369 be read after the command: splot "data" using 1:2:3 matrix
5372 2005-10-21 Ethan Merritt <merritt@u.washington.edu>
5374 * src/gp_types.h: Force enum for variable types to start at
5375 INTGR = 1, so that 0 (NULL) is guaranteed not to be a valid
5378 * src/util.c src/util.h (type_udv): New function returning the
5379 type of a user-defined variable, or 0 if there is no such udv.
5380 Replaces isstringvar().
5382 * datafile.c (plot_ticlabel_using df_readascii): Allow the
5383 using specs {x|y|z}ticlabel(<foo>) to accept an expression
5384 for <foo> rather than accepting only an integer constant.
5386 2005-10-20 Petr Mikulik <mikulik@physics.muni.cz>
5388 * src/term.c (do_arrow): Moved misplaced declaration.
5390 * config/config.cyg config/config.mgw: Updated.
5392 2005-10-19 Ethan Merritt <merritt@u.washington.edu>
5394 * docs/gnuplot.doc: Update description of xticlabels(<col>).
5396 2005-10-19 Petr Mikulik <mikulik@physics.muni.cz>
5398 * term/x11.trm (START_HELP): Update docs about window title.
5400 2005-10-16 Ethan Merritt <merritt@u.washington.edu>
5402 * src/gadgets.h: Export (BoundingBox *)clip_area, so that gnuplot
5403 core routines can specify clipping boundaries before calling
5404 clip_point() and clip_line().
5406 * src/term.c (do_arrow): clip all lines in arrow to the canvas.
5409 * src/graph3d.c (get_arrow3d): Since arrow clipping is now
5410 handled properly in do_arrow(), remove the old cruder clipping test.
5412 * term/pdf.trm (PDF_filled_polygon): Filled arrowheads can still
5413 protrude across the canvas boundary, and the pdflib routines
5414 cannot deal with this due to the use of (unsigned int) for the
5415 polygon vertices. Cast to (int) prevents segfaults or error
5416 exit by pdflib library.
5418 * term/pdf.trm (PDF_point): Bugfix: Do not crash on pointsize 0.
5420 2005-10-15 Ethan Merritt <merritt@u.washington.edu>
5422 * src/gadgets.h src/gadgets.c: Define a BoundingBox structure type,
5423 and create two instances: one for the plot boundary and one for the
5424 canvas boundary. Also export a (BoundingBox *)clip_area pointer to
5425 the currently active BoundingBox for clipping. At this point,
5426 clip_area always points to plot_bounds.
5428 * src/term.c (term_start_plot): Immediately after each call to
5429 term->graphics(), load terminal's coordinate range into canvas
5432 * src/gadgets.c (clip_point clip_line): Clip against the BoundingBox
5433 pointed to by clip_area. In the past this has always been the plot
5434 boundary, but now we will be able to use the same routines to clip
5435 against other areas.
5437 * src/graphics.c src/graph3d.c src/mouse.c: Replace all instances of
5438 xright, xleft, ytop, ybot with references to those same fields in the
5439 plot_bounds BoundingBox.
5441 * term/tkcanvas.trm: Replace xright, xleft, ytop, ybut here to.
5442 PLEASE FIX: But no terminal should be referring to these directly.
5444 2005-10-15 Hans Grobler <grobh@users.sourceforge.net>
5446 * src/gplt_x11.c: Fix buffer overflow caused by incorrect size
5447 allocation for rdbuf.
5449 2005-10-14 Ethan Merritt <merritt@u.washington.edu>
5451 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots): Explicitly
5452 initialize arrow style for "{s}plot with vector", since arrow_parse()
5453 no longer does this for us.
5455 2005-10-13 Ethan Merritt <merritt@u.washington.edu>
5457 * term/dumb.trm: Fix dumb bug in dumb term. coords run from 0->xmax
5458 and 0->ymax, but array space was only allocated for xmax*ymax pixels.
5459 Correct this to (xmax+1)*(ymax+1). Fixes segfault triggered by
5462 2005-10-12 Don Taber <dtaber@topaflyers.com>
5464 * term/pbm.trm: Update description of the PBMPLUS and NETPBM packages.
5466 2005-10-12 Ethan Merritt <merritt@u.washington.edu>
5468 * term/pslatex.trm: Add TERM_CAN_CLIP to terminal flags, since the core
5469 routines cannot correctly estimate the length of TeX strings.
5472 2005-10-12 Lars Hecking <lhecking@users.sourceforge.net>
5474 * src/beos/Makefile.in: Remove Makefile from EXTRA_DIST.
5476 2005-10-11 Ethan Merritt <merritt@u.washington.edu>
5478 * src/graph3d.c (plot3d_points): Small code clean up in preparation
5479 for possible addition of a sorting step prior to plotting.
5481 2005-10-10 Bastian Maerkisch <bmaerkisch@web.de>
5483 * src/win/winmain.c (win_lower_terminal_window): "lower" command for the
5486 2005-10-09 Harald Harders <h.harders@tu-bs.de>
5488 * src/misc.c (lp_parse arrow_parse) set.c (set_linestyle set_arrowstyle)
5489 src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots) docs/gnuplot.doc:
5491 Bring "set style line ..." and "set style arrow ..." into agreement with
5492 other "set style <foo>" commands by retaining current properties, rather
5493 than resetting to the default style each time. The previous behavior was
5494 undocumented. Add an explicit command "set style {line|arrow} default".
5496 2005-10-09 Petr Mikulik <mikulik@physics.muni.cz>
5498 * term/pdf.trm term/svg.trm (START_HELP): Small changes.
5500 * term/x11.trm (START_HELP): Reorganized list of options.
5502 2005-10-08 Bastian Maerkisch <bmaerkisch@web.de>
5504 * src/os2/gclient.c term/pm.trm: "lower" command for the pm terminal.
5506 2005-10-07 Ethan Merritt <merritt@u.washington.edu>
5508 * term/cgm.trm: Fix pattern-fill code, which was not working.
5509 If the user explicitly provides a background color, apply it to the
5510 entire canvas when plotting is started. The was documented, but
5511 apparently never implemented. Bug #616167.
5512 Also update linetype code so that it is possible to give the
5513 the background color as a line property.
5515 2005-10-07 Daniel Sebald <daniel.sebald@ieee.org>
5517 SF patch [859716] new raise/lower commands

5520 src/os2/gclient.c src/tables.c src/win/winmain.c term/pm.trm
5521 term/x11.trm: Commands "raise" and "lower" to raise and lower windows of
5522 interactive terminals.
5524 2005-10-07 Petr Mikulik <mikulik@physics.muni.cz>
5526 * src/command.c (system_command): Remove superfluous c_token++.
5528 2005-10-06 Petr Mikulik <mikulik@physics.muni.cz>
5530 * src/syscfg.h: Increased MAX_NUM_VAR from 5 to 12 (max number of
5531 parameters for functions).
5533 2005-10-06 Amitha Perera <amithaperera@users.sourceforge.net>
5535 * term/pbm.trm (PBM_options): Re-order declarations to be strict ANSI C.

5543 demo/rgb_variable.dem:
5545 Implement zzeroaxis, and rework the placement of axis tics and labels
5546 in 3D when the corresponding "set {xyz}tics axis" flag is set.
5549 2005-10-05 Ethan Merritt <merritt@u.washington.edu>
5551 * term/gd.trm (PNG_options): Test for valid (>0) size of image.
5553 2005-10-05 Bastian Maerkisch <bmaerkisch@web.de>
5555 SF RFE [1063878] Support for pre-compiled bgd.dll
5556 If gd.trm made use of the gdFontGetTiny() and related methods to read
5557 the font pointers instead of referencing them as extern, gnuplot could
5558 more easily be compiled to work with the pre-compiled GD library
5559 bgd.dll instead of having to download and compile zlib, libpng and
5562 * config/makefile.nt: Support for binary version of gdlib (bgd.dll).
5564 * term/gd.trm: New BGD_EXPORT_DATA_PROT and gp_gdXXX() for Win32.
5566 2005-10-05 Bastian Maerkisch <bmaerkisch@web.de>
5568 * term/pm.trm src/os2/pm_msgs.h src/os2/gclient.c: Support for
5569 "with image" on pm terminal.
5571 2005-10-04 Ethan Merritt <merritt@u.washington.edu>
5573 * term/pbm.trm (PBM_options): Add an option to set the output size.
5574 set term pbm size XXX,YYY
5576 2005-10-04 Bastian Maerkisch <bmaerkisch@web.de>
5578 * src/win/wtext.c (DragFunc): Increase maximum length of filenames in
5579 drag and drop operations to MAX_PATH (bug found by Tim Chippington
5582 2005-10-03 Ethan Merritt <merritt@u.washington.edu>
5584 * configure.in: Issue a warning message if someone tries to build the
5585 PNG terminal without libgd.
5587 2005-10-02 Ethan Merritt <merritt@u.washington.edu>
5589 * src/gadgets.h: Remove unused struct default_keybox_lp.
5591 * src/graph3d.c src/graph3d.h src/mouse.c src/save.c src/set.c
5592 src/show.c src/tables.c src/unset.c docs/gnuplot.doc:
5593 Move global ticslevel into a global struct xyplane that also contains a
5594 flag indicating whether the value fixes the Z-intercept of the x/y plane
5595 at a fraction of the z range (old behaviour) or a specific value of
5596 Z (new option). To select a specific Z, use "set ticslevel at <zval>".
5597 This change also introduces "xyplane" as a synonym for "ticslevel",
5598 so the more easily remembered form of the command is
5599 "set xyplane at <zval>".
5601 * src/graph3d.c (do_3dplot): Check for absolute placement of xyplane
5602 along Z axis, controlled by "set {ticslevel|xyplane} at <zval>".
5604 2005-10-01 Ethan Merritt <merritt@u.washington.edu>
5606 Lines have more properties now than they used to. Rather than expanding
5607 the number of parameters to lp_parse() to pass default values for each
5608 property separately, change to requiring the caller of lp_parse() to
5609 preload default values into the lp_style_type structure being passed.
5610 This change should not by itself affect current syntax or behaviour,
5611 but will allow us to remove the style initialization from lp_parse().
5612 This in turn will allow different callers to have different default
5613 line styles while still sharing the same parsing routine.
5615 * src/misc.h src/misc.c (lp_parse): Remove def_line and def_point
5616 parameters; instead assume they have been preloaded into lp.
5618 * src/plot2d.c src/plot3d.c src/set.c: Modify all callers of lp_parse()
5619 to follow the new scheme.
5621 * src/gadgets.h src/term_api.h src/graph3d.c src/graphics.c src/save.c
5622 src/plot2d.c src/plot3d.c: #define PTSZ_VARIABLE and PTSZ_DEFAULT as
5623 constants rather than passing magic values for lp_style_type.p_size.
5625 * src/term.c (term_apply_lp_properties): Check explicitly for
5626 PTSZ_VARIABLE and PTSZ_DEFAULT.
5628 2005-09-29 Ethan Merritt <merritt@u.washington.edu>
5630 * src/axis.c (axis_position_zeroaxis): More zeroaxis bugs; does nobody
5631 ever use this option? Range terminating at 0.0 is a perfectly valid
5632 case in which to draw a zeroaxis.
5635 2005-09-27 Ethan Merritt <merritt@u.washington.edu>
5637 * src/util3d.c (draw3d_line_unconditional): The code previously assumed
5638 that any 3D colored line is colored by Z value. This is no longer true.
5641 2005-09-27 Petr Mikulik <mikulik@physics.muni.cz>
5643 * term/post.trm (PS_COMMON_DOC1): More details for 'color' and
5644 'monochrome' options.
5646 2005-09-25 Ethan Merritt <merritt@u.washington.edu>
5648 Even when gnuplot honors a LOCALE setting for input of data or output
5649 of plots, gnuplot's own command syntax requires LC_NUMERIC == C. We
5650 must check for this anywhere that a command is generated or parsed.
5652 * src/mouse.c (apply_zoom): Enforce C locale before creating
5653 command sequence to do zooming.
5655 * src/scanner.c (get_num): Enforce C locale before reading a number
5656 that is part of a command line.
5658 * src/command.c (save_command test_palette_subcommand)
5659 src/show.c (show_command show_style): Enforce C locale before saving or
5660 showing state of internal variables.
5662 2005-09-25 Petr Mikulik <mikulik@physics.muni.cz>
5664 * term/svg.trm (SVG_init): Encodings for OS/2 and Windows.
5666 2005-09-24 Bastian Maerkisch <bmaerkisch@web.de>
5668 * src/os2/gclient.c term/pm.trm: Full RGB colour support for pm terminal
5669 (if display supports it).
5671 2005-09-24 Ethan Merritt <merritt@u.washington.edu>
5673 * src/gplt_x11.c (process_event): Drain any backlog of keypress
5674 events from the current plot window every time we see an arrow key.
5675 This prevents hysteresis if the redraw rate is slower than the
5676 keyboard autorepeat rate.
5679 * term/emf.trm: (EMF_dashtype): Make axis dotted by default, consistent
5680 with other terminal types.
5682 2005-09-23 Ethan Merritt <merritt@u.washington.edu>
5684 * src/gplt_x11.c (exec_cmd) term/x11.trm (ENHX11_put_text):
5685 Change the vertical centering of enhanced mode text so that it matches
5686 that of non-enhanced text.
5688 2005-09-23 Petr Mikulik <mikulik@physics.muni.cz>
5690 * src/set.c term/gd.trm: Always allow animated gif options in
5691 'set term gif ...'. Issue a warning if the gd library does not support
5694 2005-09-22 Ethan Merritt <merritt@u.washington.edu>
5696 * src/graphics.c (boundary do_plot label_width): Correct the layout
5697 of the key title area for enhanced text super- and sub- scripts, and
5698 ensure the box is wide enough for the key title string.
5701 NB: This fix reveals that the x11 driver has incorrect vertical
5702 centering for enhanced text; other drivers are fine.
5704 * term/xlib.trm: Add enhanced text entry points to TERM_TABLE so that
5705 enhanced text handling by x11 driver can be debugged.
5707 2005-09-21 Ethan Merritt <merritt@u.washington.edu>
5709 * term/svg.trm (SVG_init): Place encoding information in the
5710 XML header record if an encoding is explicitly set in gnuplot.
5713 * src/axis.c (gen_tics): Correct the calculation of last minitic
5714 position to be plotted on a log-scale axis. Bug #1223149.
5716 * src/term.c (write_multiline): Fix trivial line-counting bug.
5718 2005-09-20 Ethan Merritt <merritt@u.washington.edu>
5720 * src/set.c (parse_label_options): Fix incorrect ordering of
5721 declaration/initialization. Non-gcc compilers didn't like it.
5723 2005-09-19 Ethan Merritt <merritt@u.washington.edu>
5725 * src/graphics.c (boundary): Allow space for zeroaxis tic labels when
5726 zeroaxis is near plot border. Bug #219867 swatted after 5 years!

5732 src/show.c (show_ticdef) src/unset.c (unset_tics) docs/gnuplot.doc:
5734 Sourceforge patchset #1104018.
5735 Allow both user-specified axis tics and auto-generated tics at the
5736 same time. No change to basic syntax or behaviour of tics, but the
5737 extra key word "add" in a "set [xuz]tics ..." command causes the
5738 requested tics to be added to the current ones rather than replacing
5741 2005-09-17 Ethan Merritt <merritt@u.washington.edu>
5743 * src/graphics.c (plot_image_or_update_axes): Use gp_alloc rather
5744 than malloc. Bug #1254314.
5746 * src/gplt_x11.c src/getcolor.c: Check for NULL return from malloc().
5749 * demo/all.dem: Fixed mis-matched quotes around "rgb_variable.dem".
5751 2005-09-16 Juergen Wieferink <wieferink@freenet.de>
5753 * src/command.c (string_expand): Fix bug in macro handling; escaped
5754 quotes were not recognized.
5756 2005-09-16 Ethan Merritt <merritt@u.washington.edu>
5758 * src/graph3d.c (draw_3d_graphbox): Treat placement of Z-axis label in
5759 the same way as those for the X and Y axes.
5761 2005-09-15 Ethan Merritt <merritt@u.washington.edu>
5763 * src/term.c (write_multiline, on_page): New routine on_page(x,y) to
5764 check coordinates for being in range of entire terminal drawing area.
5765 Use this in write_multiline() to centralize text clipping (may extend
5766 it to single line text later). Fixes bug #1274007 and a lot of old
5767 complaints about segfaults in libpdf.
5769 * src/term_api.h term/post.trm: But some terminals can clip text just
5770 fine on their own, and do it more cleanly than on_page() can do. Define
5771 a terminal flag TERM_CAN_CLIP for these cases, starting with post.trm.
5772 If the flag is set for the current terminal, on_page() always returns
5775 * src/graph3d.c (xtick_callback ytick_callback ztick_callback):
5776 Since write_multiline() now does its own clipping, it does not need to
5777 be wrapped by clip_put_text_just(). While we're here, apply text
5778 rotation for tic labels.
5780 * src/gadgets.c src/gadgets.h src/color.c: This leaves no callers for
5781 clip_put_text_just(), so remove the routine altogether.
5783 2005-09-15 Harald Harders <h.harders@tu-bs.de>
5785 * src/variable.c term/post.trm (PS_options, documentation):
5786 Fix bugs in fontfile handling of ps terminal. Document "nofontfiles".
5787 SourceForge patch #1269469.
5789 2005-09-15 Ethan Merritt <merritt@u.washington.edu>
5791 * demo/html/Makefile demo/html/index.save: Add rgb_variable.dem to the
5792 autogenerated html set. Also add dashcolor.dem, which is complicated
5793 by needing to generate an *.eps file and then convert it to *.png.
5795 * demo/all.dem: Add rainbow.dem and rgb_variable.dem
5797 * src/gadgets.h: Initialize axis labels to use linetype -1, not 0.
5799 2005-09-14 Ethan Merritt <merritt@u.washington.edu>
5801 * docs/gnuplot.doc: The histogram plot style was not being listed as an
5802 option under 'help plotting styles'.

5807 src/graph3d.c src/graphics.c src/save.c src/set.c src/show.c src/term.c
5809 Up till now gnuplot's axis labels, plot title, and timestamp have been
5810 stored in statically allocated instances of struct label_struct.
5811 All other labels use dynamically allocated struct text_label.
5812 This set of changes converts all users of struct label_struct to use
5813 stucture text_label instead. This saves space everywhere, and
5814 consolidates the label parsing and handling routines.
5816 * docs/gnuplot.doc NEWS:
5817 The y and y2 axis labels now allow explicit control over rotation angle;
5818 all labels now allow explicit control over {no}enhanced text processing.
5820 2005-09-12 Bastian Maerkisch <bmaerkisch@web.de>
5822 * config/config.nt: Rearranged to comply with config.{h,cyg,mgw,os2}.
5824 2005-09-11 Ethan Merritt <merritt@u.washington.edu>
5826 * src/save.c (save_set_all): Fix incorrect placement of newlines
5827 in "set pm3d" options.
5829 2005-09-09 Lars Hecking <lhecking@users.sourceforge.net>
5831 * Makefile.am: Add DISTCLEANFILES.
5833 * lisp/Makefile.am: Add $(ELS) to distclean-local target.
5835 * share/LaTeX/Makefile.am: Install .cfg file under gnuplot's directory
5836 hierarchy rather than LaTeX's - it is the user's responsibility to
5837 update the latter. Add uninstall-hook.
5839 2005-09-09 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
5841 * config/config.nt: Added flags for GP_ISVAR, libPDF details,
5842 HAVE_STRINGIZE, string variables, datastrings, histograms, fit
5843 error variables, image mode, macros. Added at least some
5846 2005-09-08 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
5848 * config/makefile.nt: Add a rule that makes all *.obj files
5849 explicitly dependent on config.h. Explain usage a bit more
5852 * src/graphics.c (plot_image_or_update_axes): Don't dereference
5853 function pointer in test.
5855 * docs/gnuplot.texi: Regenerated.
5857 * docs/gnuplot.doc: Removed superfluous blanks, fixing some
5860 * src/beos/Makefile.in: New file. Edited copy of previous
5861 Makefile to fix out-of-source 'make dist'.
5863 * src/beos/Makefile: Removed.
5865 * configure.in: Add src/beos/Makefile to AC_OUTPUT.
5867 2005-09-07 Lars Hecking <lhecking@users.sourceforge.net>
5869 * Makefile.am, configure.in, share/Makefile.am: SUBDIRS in
5870 automake versions older than 1.9 can only contain direct
5871 children. Need a minimal, dummy Makefile.am in share/ to address
5874 * configure.in, share/Makefile.am, share/LaTeX/Makefile.am: Fix
5875 building outside source directory.
5877 2005-09-07 Lars Hecking <lhecking@users.sourceforge.net>
5879 * Makefile.am: Add share/LaTeX to SUBDIRS.
5881 * depcomp, install-sh, missing, mkinstalldirs: Updated from
5884 * config/Makefile.am.in: Add MacOSX to EXTRA_DIST generation.
5886 * demo/Makefile.am.in: Add *.cfg and html to EXTRA_DIST
5887 generation, remove webify.pl.
5889 * share/LaTeX: Add top_srcdir, INSTALL_DATA, DISTFILES, install,
5890 distdir, clean, distclean. Clean up all and install targets.
5892 * src/Makefile.am: Add makefile.awc to EXTRA_DIST.
5894 2005-09-05 Petr Mikulik <mikulik@physics.muni.cz>
5896 * show.c (show_palette_palette): Take care that print_out is
5897 stderr for for both NULL and stderr.
5899 * command.c (print_show_output): Make the test to print_out, not
5900 print_out_name (failed for stdout).
5902 2005-09-05 Geoffrey Hausheer <ghaushe@users.sourceforge.net>
5904 SF patch [1264939] Adds bilinear interpolation to pm3d surfaces
5906 * demo/pm3d.dem docs/gnuplot.doc src/pm3d.c src/pm3d.h src/save.c
5907 src/set.c src/show.c src/tables.c src/tables.h NEWS: When using
5908 pm3d with data files (rather than functions), a single color is
5909 used for each quadrangle (unless dgrid is used, but then you get
5910 weighted averages instead). This patch does bilinear interpolation
5911 to subdivide each quadrangle into nxn smaller quadrangles, and
5912 sets the color of each one independantly.
5914 2005-08-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
5916 * config/makefile.dj2 (TERMLIBS): Updated to current version of
5918 (LINKOPT): Fix it to actually use $(TERMLIBS).
5919 (CFLAGS): Add -DHAVE_SYS_STAT_H.
5921 2005-08-30 Bastian Maerkisch <bmaerkisch@web.de>
5923 * src/os2/gclient.c (ReadGnu): implement stubs in pm terminal to
5924 map RGB colors to nearest color from current pm3d palette
5926 2005-08-22 Ethan Merritt <merritt@u.washington.edu>
5928 * src/color.c src/color.h: New routine set_rgbcolor().
5930 * src/misc.c (parse_colorspec) src/graph3d.c: Allow color
5931 specification "rgb variable", in which case the RGB color is taken
5932 from an additional field of the "using" specifier.
5934 * docs/gnuplot.doc demo/rgb_variable.dat demo/rgb_variable.dem NEWS:
5935 Explain and give example of reading rgb color from input data field.
5937 2005-08-19 Ethan Merritt <merritt@u.washington.edu>
5939 * src/plot3d.c (get_3ddata) src/graph3d.c(plot3d_points):
5940 Variable pointsize should be honored in plot style "linespoints"
5941 exactly as in style "points".
5943 2005-08-17 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
5945 * docs/gnuplot.doc (multiplot): Extend description of how
5946 multiplot actually works on interactive displays. Place a hint
5947 about using 'clear' for insets. Closes RFE #1256148.
5949 2005-08-16 Harald Harders <h.harders@tu-bs.de>
5951 * src/save.c (save_tics): Fix inconsistency in the syntax of the saved
5952 "set tics" command and the input "set tics" command. SF patch [1261165]
5954 2005-08-12 Juergen Wieferink <wieferink@freenet.de>
5956 * src/datafile.c (initialize_use_spec df_open df_close)
5957 src/fit.c (error_ex fit_command) src/set.c (set_palette_function):
5958 Use free_at() rather than free() for action table pointers.
5959 Fixes minor memory leaks found by valgrind.
5961 * src/eval.c (free_at): Handle null pointer gracefully.
5963 * src/gadgets.h src/graphics.h src/plot2d.c src/plot3d.c:
5964 Consistent initialization of the title_no_enhanced flag.
5966 2005-08-12 Bastian Maerkisch <bmaerkisch@web.de>
5968 SF patch [1234632] gnuplot history file without GNU readline
5970 * NEWS src/gp_hist.h src/history.c src/plot.c src/set.c src/show.c
5971 src/syscfg.h src/unset.c: This patch enables GNUPLOT_HISTORY if gnuplot
5972 is not compiled with GNU readline. History is automatically saved on
5973 program exit and reloaded on start. "set/unset history" commands are
5976 * configure.in config/makefile.os2: Other makefiles should be adjusted
5977 to allow GNUPLOT_HISTORY to be defined when HAVE_LIBREADLINE is not.
5979 2005-08-10 Ethan Merritt <merritt@u.washington.edu>
5981 * src/gplt_x11.c: Restore original background pixel setting after
5984 2005-08-10 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
5986 * src/win/winmain.c: Define _WIN32_IE independent of particular
5987 compilers, conditional only on whether it's already defined.
5989 2005-08-08 Ethan Merritt <merritt@u.washington.edu>
5991 * term/pdf.trm: Keep track of current color regardless of whether
5992 it was set by term->set_color() or term->linetype().
5994 2005-08-08 Bastian Maerkisch <bmaerkisch@web.de>
5996 * src/gp_hist.h src/history.c src/plot.c src/plot.h src/set.c
5997 src/show.c src/unset.c: Move variable gnuplot_history_size from
5998 plot.h to gp_hist.h.
6000 2005-08-08 Petr Mikulik <mikulik@physics.muni.cz>
6002 * demo/datastrings.dem demo/epslatex.dem demo/histograms.dem
6003 demo/layout.dem demo/pm3d.dem: Update for "set tics scale".
6005 2005-08-07 Ethan Merritt <merritt@u.washington.edu>
6007 * src/gplt_x11.c: Do away with special (GC *)gc_pm3d; use the same gc
6008 for all normal plot elements except pattern fill. Tweak the algorithm
6009 for text rotation as suggested long ago by Dave Denholm. The default
6010 method should now work on all TrueColor or DirectColor displays. The
6011 X resource "gnuplot*fastrotate: off" still allows fall-back to a slower
6012 but guaranteed algorithm if necessary. Fixes bug #1251193.
6014 2005-08-07 Petr Mikulik <mikulik@physics.muni.cz>
6016 Let PM3D be always compiled in. Thus, this patch removes all constructs
6017 #if(n)def PM3D and does a necessary code clean-up.

6047 * src/set.c (set_tics): Fix non-ANSI ordering of declaration.
6049 2005-08-06 Ethan Merritt <merritt@u.washington.edu>
6051 * src/color.c: Remove C++ style comments.
6053 * src/gplt_x11.c: Replace non-standard type caddr_t with XPointer.
6055 * src/set.c (set_tics) src/tables.c src/tables.h: Do not consider
6056 use of old syntax as an error. (E.g. 'set key outside below')
6058 2005-08-05 Ethan Merritt <merritt@u.washington.edu>
6060 * demo/starmap.dem: Change style slightly for use with webify.

6068 SF patch [1245558] Different ticscale and ticpos for different axes
6070 * NEWS docs/gnuplot.doc src/axis.c src/axis.h src/color.c src/graph3d.c
6071 src/graphics.c src/save.c src/set.c src/show.c src/term.c src/unset.c
6072 demo/all.dem demo/tics.dem demo/html/Makefile: This patch enables the
6073 user to specify different ticscales and tic-positions for each axis:
6074 - new: "set tics" can change most settings for {x|y|z|cb}tics at once;
6075 - new: tic scale can be set per axis using "set {x|y|z|cb}tics scale";
6076 - change: "set ticsscale" is deprecated, use "set tics scale" instead.
6078 2005-08-04 Ethan Merritt <merritt@u.washington.edu>
6080 * src/plot2d.c(store_label get_data) src/plot3d.c (get_3ddata):
6081 For 'plot with labels', instead of treating a missing label as an
6082 undefined point, treat it as a blank label. That allows putting a
6083 point on the plot even if there is no label to go with it.
6086 * src/datafile.c: Better fix for mis-match of column header to column
6087 values in the case of `set style histogram errorbars` with
6088 `set key autotitle columnheader`. Supersedes 2005-07-30 patch.
6090 2005-08-04 Bastian Maerkisch <bmaerkisch@web.de>
6092 SF patch [1233984] Directory selection dialog for Win32
6094 * src/win/wgnuplot.mnu src/win/wmenu.c: Add new directory selection
6095 dialog to Win32 platform. If SHELL_DIR_DIALOG is defined the common
6096 directory dialog of the windows shell is used. Otherwise a modified
6097 version of the common file open dialog is used. The new code is only
6098 active if WITH_ADV_DIR_DIALOG is defined.
6100 * src/win/wcommon.h: Make the new directory dialog the default by
6101 #defining WITH_ADV_DIR_DIALOG and SHELL_DIR_DIALOG.
6103 2005-08-04 Bastian Maerkisch <bmaerkisch@web.de>
6105 SF patch [1233987] WIN32: save wgnuplot.ini to user's appdata dir
6107 * src/plot.c src/plot.h src/win/winmain.c (WinMain): Change default
6108 location of wgnuplot.ini to the user's APPDATA directory on Win32
6109 platforms. This is necessary since the directory of the executable can
6110 not be assumed to be writable.
6112 * src/win/wcommon.h: Make the new behaviour the default by #defining
6115 2005-08-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
6117 * src/contour.c: CodeStyle cleanup (no superfluous pointer casts,
6118 sensible indentation).
6119 (contour): Logarithmize parameters of incremental
6120 contour specification to imitate the way other ticks on log axes
6122 (edge_struct, poly_struct, cntr_struct): Typedef'd these structs,
6123 use typedef names all over the place to render source less wordy.
6125 2005-08-03 Ethan Merritt <merritt@u.washington.edu>
6127 Move generation of html demo files into a separate subdirectory.
6129 * demo/html/index.save demo/html/gnuplot_demo.css:
6130 Template files for html pages.
6132 * demo/html/Makefile demo/html/webify.pl: Modify webify.pl to accept
6133 the "set term" parameters from environmental variable DEMOTERM. Create
6134 a separate Makefile just for generation of html pages. Add special
6135 case terminal parameters for several demos.
6137 * demo/multiplt.dem: Add a missing "pause -1" command so that the
6138 webify script works properly.
6140 2005-08-03 Lars Hecking <lhecking@users.sourceforge.net>
6142 * docs/Makefile.in: Update CLEANFILES and clean-generic.
6144 2005-08-03 Bastian Maerkisch <bmaerkisch@web.de>
6146 * config/makefile.nt: Introduce variable OPTIONS for compile time
6147 switches like PM3D, USE_MOUSE etc. This makes addition of options
6150 * src/win/winmain.c src/win/wcommon.h: Add new function GetDllVersion()
6151 which can determine the version of windows's shell and common control
6152 libraries. It is only included if WANT_GETDLLVERSION is defined.
6154 * src/win/wprinter.c src/win/wgraph.c src/win/wgnuplib.h
6155 src/win/wcommon.h: Rename struct PRINT to GP_PRINT due to name
6156 collision with windows shlobj.h header file.
6158 2005-08-02 Petr Mikulik <mikulik@physics.muni.cz>
6160 * config/config.mgw: Some more #(un)define for MingW >= 3.0.
6162 2005-08-01 Ethan Merritt <merritt@u.washington.edu>
6164 * src/save.c (save_position): OK, so maybe we have to print out
6165 the full "offset ...." even if it specifies zero offset.
6167 2005-07-31 Petr Mikulik <mikulik@physics.muni.cz>
6169 * src/history.c: Removed old comments.
6171 2005-07-31 Bastian Maerkisch <bmaerkisch@web.de>
6173 * src/plot.c: #include gpexecute.h for OS/2 without USE_MOUSE.
6175 * src/show.c (show_version): Correct spelling error HIDDEN3D_GRDBOX =>
6178 * src/term.h: Fix compilation with SHORT_TERMLIST.
6180 * src/gplt_x11.c: Remove reference to os2/dialogs.h.
6182 * src/mouse.c: Use OS/2 message definition file os2/pm_msgs.h.
6184 * config/makefile.os2: Fix build of gplt_x11.exe on OS/2.
6186 2005-07-30 Petr Mikulik <mikulik@physics.muni.cz>
6188 * config/config.mgw: Have HAVE_ERF, HAVE_ERFC for MingW >= 3.0.
6190 2005-07-30 Ethan Merritt <merritt@u.washington.edu>
6192 * src/save.c (save_position and its callers): Move printout of the
6193 "offset" keyword into shared routine save_position(). That way we
6194 can efficiently skip the whole thing if the offset is zero.
6196 * src/datafile.c (df_tokenise): Add back a copy and a comment
6197 corresponding to the old sscanf() input code. This makes is easy if
6198 someone wants to compare new and old code paths.
6200 * src/datafile.c (df_open): Fix mis-match of column header to
6201 column values in the case of `set style histogram errorbars` with
6202 `set key autotitle columnheader`.
6204 2005-07-29 Petr Mikulik <mikulik@physics.muni.cz>
6206 * demo/pm3d.dem: Added missing text for a "pause -1".
6208 2005-07-29 Daniel Sebald <daniel.sebald@ieee.org>
6210 * src/gadgets.h src/graph3d.c src/graphics.c src/save.c src/set.c
6211 src/show.c src/tables.c src/tables.h: Revamping of key placement
6212 routines. Backward compatible with previous placement options but now
6213 there are new, more flexible options.
6215 {{inside | outside} | {lmargin | rmargin | tmargin | bmargin}
6217 {left | right | center} {top | bottom | center}
6218 {vertical | horizontal} {Left | Right}
6220 controlling key placement and key element arrangement.
6222 * docs/gnuplot.doc: Updated documentation about new key options.
6223 "at" for manual placement was included in the documentation even though
6224 leaving "at" out will still work.
6226 * demo/bivariat.dem demo/electron.dem tutorial/eg3.plt tutorial/eg6.plt
6227 tutorial/tutorial.tex: Changed all uses of manual key placement to
6230 * demo/key.dem demo/all.dem: Added demo to show variety of key
6231 placements, and added demo to the all demo file.
6233 * NEWS: Added note about more versatile key placement.
6235 2005-07-28 Ethan Merritt <merritt@u.washington.edu>
6237 * src/term.c (term_start_multiplot mp_layout_size_and_offset):
6238 `set multiplot {title "string"} {layout ... }`
6239 Add a page title option for multiplots. In auto-layout mode,
6240 reserve space at the top of the page for this title, and scale
6241 all the component plots accordingly. RFE #992349
6243 * demo/layout.dem: Add sample titles to the plots in this demo.
6245 * src/graphics.c (place_histogram_titles): Fix bug that tried to get
6246 the title offsets from the wrong data structure.
6248 2005-07-28 Petr Mikulik <mikulik@physics.muni.cz>
6250 * config/config.cyg config/config.mgw config/config.os2: Added #defines
6251 GP_MACROS, GP_STRING_VARS, HIDDEN3D_GRIDBOX, HIDDEN3D_QUADTREE,
6252 HAVE_PWD_H, __PROTOTYPES.
6254 2005-07-28 Bastian Maerkisch <bmaerkisch@web.de>
6256 SF patch [1234634] OS/2: use generic enhanced text in pm terminal.
6258 * config/config.os2 config/makefile.os2 src/os2/gclient.c
6259 src/os2/gnupmdrv.c src/os2/gnupmdrv.h src/os2/pm_msgs.h term/pm.trm:
6260 Use generic enhanced text in pm terminal -- Let pm terminal use the
6261 new generic routines for enhanced text. Currently the only new feature
6262 this provides is overprinted text. The binary interface between pm.trm
6263 and gnupmdrv has been extended slightly.
6265 To switch back to the old behaviour compile with PM_OLD_ENHANCED_TEXT
6266 defined. The old code is compiled into gnupmdrv in any case to
6267 maintain binary compatibility with programs using gnupmdrv like GP/ARI
6268 or Term::Gnuplot (but I haven't acually checked that).
6270 2005-07-27 Ethan Merritt <merritt@u.washington.edu>
6272 * src/set.c (set_timestamp) docs/gnuplot.doc:
6273 Drag the "set timestamp" code into the modern era by accepting options
6274 in any order. Add keyword "font" in front of the optional font string,
6275 but for backwards compatibility do not require it. Update the
6276 documentation to reflect current treatment of offset and font options.
6278 2005-07-26 Ethan Merritt <merritt@u.washington.edu>
6280 * src/set.c (set_xyzlabel): Check to see if next token is a valid
6281 keyword before trying to parse it as a string. Fixes bug on, e.g.
6282 'set title offset 1,1'
6284 * src/save.c (save_set_all): Write out keyword "offset" where
6287 2005-07-25 Ethan Merritt <merritt@u.washington.edu>
6289 * src/stdfn.c src/stdfn.h: Add a private function gp_strtod() in case
6290 there are platforms that do not have a working strtod().
6292 * src/datafile.c (df_tokenise): Use strtod(), via gp_strtod(),
6293 to parse values read from a data file. On long input lines, this is
6294 substantially faster than using sscanf(). The previous fast path
6295 (non-Fortran) used atof() rather than strtod(), but that does not
6296 give a status return or character length consumed.
6298 2005-07-25 Ethan Merritt <merritt@u.washington.edu>
6300 * term/pdf.trm (PDF_options PDF_linewidth): libpdf does not like zero
6301 linewidth. Limit linewidths to 0.1 or greater.
6303 * src/command.c (exit_command) docs/gnuplot.doc:
6304 New command 'exit gnuplot' will unconditionally exit gnuplot immediately
6305 even if invoked from within several nested layers of input stream. This
6306 allows, for instance, binding a hotkey that can terminate gnuplot in
6307 response to a keystroke in the plot window.
6309 2005-07-25 Ethan Merritt <merritt@u.washington.edu>
6311 * src/datafile.c src/datafile.h src/save.c src/set.c src/show.c
6312 src/unset.c docs/gnuplot.doc:
6313 New command 'set datafile fortran' to enable parsing of input files
6314 containing Fortran D or Q floating constants. This was the default
6315 until now, but it requires a second check of every value parsed,
6316 which obviously slows down the input procedure. Now the second pass
6317 is disabled by default, and only occurs if the fortran parsing option
6318 is selected. Addresses complaints of slow input from large files.
6320 2005-07-23 Ethan Merritt <merritt@u.washington.edu>
6322 * src/command.c (print_command): Re-arrange code so that an expression
6323 being printed is only evaluated once, rather than twice.
6326 2005-07-23 Harald Harders <h.harders@tu-bs.de>
6328 * src/term.c (write_multiline): Use estimate_strlen rather than strlen.
6330 * term/post.trm: Use a more foolproof method of estimating the width of
6331 strings containing overprint characters.
6333 2005-07-22 Ethan Merritt <merritt@u.washington.edu>
6335 * src/parse.c (string_or_express): Remove unused variable.
6337 2005-07-22 Ethan Merritt <merritt@u.washington.edu>
6339 Introduce a new terminal API routine (term->layer)(int layer). This
6340 is used by the epslatex terminal (pslatex.trm) to handle the
6341 "front" or "back" text attribute. In the future it might be used to
6342 toggle other layering effects (transparency? contour levels?).
6344 * src/term_api.h term/README: Define new entry point and a set of
6345 layer names to pass into it.
6347 * src/graph3d.c (do_3dplot) src/graphics.c (do_plot):
6348 Call t->layer(TERM_LAYER_FRONTTEXT) and t->layer(TERM_LAYER_BACKTEXT)
6349 at the relevant stages of plot generation.
6351 * src/term.c (term_start_plot term_end_plot):
6352 Call t->layer(TERM_LAYER_RESET) and t->layer(TERM_LAYER_END_TEXT)
6353 at start and end of each plot, respectively.
6355 * term/pslatex.trm: Implement EPSLATEX_layer() mechanism.
6357 2005-07-20 Juergen Wieferink <wieferink@freenet.de>
6359 * src/parse.c (string_or_express): Do not call int_error() for invalid
6360 expressions. Fixes "(s)plot 1/0".
6362 2005-07-19 Ethan Merritt <merritt@u.washington.edu>
6364 * term/cgm.trm: Add a warning that Win2000 cannot handle filled
6365 polygons with more than 50 vertices. Not our fault! Bug #955074.
6367 2005-07-18 Ethan Merritt <merritt@u.washington.edu>
6369 * src/datafile.c (df_parse_string_field): Fix tab-containing string
6370 constant which was broken when indent replaced tabs with spaces.
6372 * configure.in src/term.h term/post.h term/post.trm term/pslatex.trm:
6373 Repair the ordering of configuration options for building the post,
6374 epslatex, and pslatex terminals. This selection is now made at the top
6375 of term.h, as is selection of the enhanced text stringlength estimation
6378 2005-07-16 Juergen Wieferink <wieferink@freenet.de>
6380 * src/command.c (load_command): Issue an error message if any
6381 tokens or further commands follow a "load <file>" command.
6382 Sourceforge patch #1210835.
6384 2005-07-16 Ethan Merritt <merritt@u.washington.edu>
6386 * demo/stringvar.dem: Add a demo showing a plot command that
6387 generates datafile names via a string-valued function, now possible
6388 because of the new string_or_expression code.
6390 2005-07-16 Juergen Wieferink <wieferink@freenet.de>
6392 Allow a single plot or splot command to contain a mixture of
6393 functions, e.g. sin(x), and constant expressions including
6394 string-valued constant expressions, e.g. sprintf("file.%d",n).
6396 * src/datafile.c (df_open) src/datafile.h src/plot2d.c
6397 src/plot3d.c src/fit.c src/set.c:
6398 Parse filename from plot/splot/fit command before calling df_open(),
6399 and pass the resulting string to df_open() as a new argument.
6401 * src/parse.c (string_or_expression) src/parse.h:
6402 New function that can safely parse either a constant expression
6403 or a dummy function. string_or_expression() will return a pointer
6404 to a string if it successfully parsed a string-valued expression.
6405 It will return a pointer to an action table if it successfully
6406 parsed a dummy function. If it parsed a non-string expression, both
6407 the string pointer and the action table pointer will be NULL.
6409 * src/eval.c (imag):
6410 The use of string_or_expression() by splot/plot/fit allows one to
6411 mix string-valued functions and "true" functions in the same command.
6412 However, a string-valued function containing what looks like a dummy
6413 variable (normally x or y) is not parsed correctly. This error is
6414 eventually discovered and reported in imag().
6416 2005-07-16 John Bollinger <bbands@yahoo.com>
6418 * demo/finance.dem demo/finance.dat: New demo illustrating
6419 various gnuplot features applied to display of financial data.
6421 2005-07-15 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
6423 * src/term.c (enhanced_recursion) [POSTSCRIPT_DRIVER]: added
6424 a conditional to allow builds without PostScript/pslatex drivers
6427 * term/pslatex.trm (PSLATEX_DRIVER): Define this macro here, where
6430 * term/post.trm (POSTSCRIPT_DRIVER): Likewise.
6432 * term/post.h: Remove #define PSLATEX_DRIVER --- it had no
6433 business sitting in here.
6435 * src/term_api.h (PC_setup) [PC]: Add missing prototype.
6437 * src/gadgets.c: Add missing #include "graph3d.h".
6439 * src/datafile.c: Re-indented almost the entire file. Was
6440 violating CodeStyle all over the place.
6442 * src/term.h [DJGPP, DJSVGA]: Allow build without GRX (by setting
6445 * config/makefile.dj2 (EXENAME): Removed version number from name.
6446 (TERMFLAGS): DJSVGA definition moved to front, explain that
6447 setting this to zero has a different effect now.
6448 (TERMLIBS): Renamed to usual name (was LDFLAGS).
6449 (CFLAGS): Updated to support build of current source.
6450 (LINKOPT): Removed entry for GRX library.
6452 * src/breaders.h: Added missing HAVE_CONFIG_H conditional.
6454 2005-07-14 Ethan Merritt <merritt@u.washington.edu>
6456 * src/internal.c src/term.c src/gplt_x11.c term/gd.trm: Fix mangled use
6457 of FPRINTF debugging macro.
6459 * term/README term/gd.trm: Clarify documentation of term->suspend and
6460 term->resume. Remove TERM_CAN_MULTIPLOT flag from gd.trm, since it has
6461 no suspend/resume entry points.
6463 2005-07-13 Ethan Merritt <merritt@u.washington.edu>
6465 * src/command.c (do_system_func): Fix incorrect placement of final
6466 return code outside of the main conditional code segment.
6467 Fixes compilation error under mingw reported by Dietmar Warning.
6469 * src/graph3d.c (do_3dplot) src/graphics.c (do_plot)
6470 src/term.c (test_term) term/post.trm term/pslatex.trm:
6471 Remove all epslatex-specific code from the gnuplot core routines.
6472 It was not working anyhow. This reverts the epslatex driver to
6473 the old behaviour of ignoring any distinction between "front" and
6474 "back" text labels. It also clears the deck for a different
6475 approach that adds a terminal API routine to handle this sort of
6476 terminal-specific requirement (SourceForge patchset #1191202).
6478 2005-07-11 Ethan Merritt <merritt@u.washington.edu>
6480 * src/breaders.h src/datafile.c src/datafile.h src/fit.c src/plot2d.c
6481 src/plot3d.c src/set.c: Simplify conditional compilation controlled by
6482 --enable-binary-data-file. Instead of having a different number of
6483 parameters to df_readline() and plot_option_binary(), expost a uniform
6484 definition but add an auxilliary routine df_set_plot_mode() in the
6485 BINARY_DATA_FILE case. Also clean up the general coding style and remove
6486 redundant structure definitions. This prepares for easier implementation
6487 of Juergen Wieferink's "plot string or expression" patch.
6489 2005-07-10 Harald Harders <h.harders@tu-bs.de>
6491 * docs/psdoc/ps_symbols.gpi: Spiffed up sample page for PostScript
6492 symbols and linetypes.
6494 2005-07-10 Shigeharu Takeno <shige@iee.niit.ac.jp>
6496 * docs/gnuplot.doc: Fix typos.
6498 2005-07-10 Ethan Merritt <merritt@u.washington.edu>
6500 * src/command.c src/graph3d.c src/graphics.c src/term.c:
6503 * src/internal.c (f_gprintf): Use dynamic allocation for output buffer.
6505 2005-07-10 Juergen Wieferink <wieferink@freenet.de>
6507 * src/command.c (do_system_func) src/command.h src/eval.c
6508 src/internal.c (f_system) src/internal.h src/scanner.c (substitute):
6509 New built-in string function system("command") which executes a shell
6510 command and returns the resulting output stream as a string variable.
6511 Consolidate this code with existing shell escape code (backticks) via
6512 a new routine do_system_func().
6514 * docs/gnuplot.doc: Document new system("command") function.
6516 2005-07-09 Juergen Wieferink <wieferink@freenet.de>
6518 * src/eval.c src/eval.h src/parse.c src/parse.h: Consolidate code
6519 in add_udv() and add_udv_by_name(). Move add_udv_by_name() from parse.c
6520 to eval.c so that lower level routines in internal.c and eval.c do not
6521 have to include parse.h.
6523 2005-07-08 Juergen Wieferink <wieferink@freenet.de>
6525 * src/internal.c (f_call f_calln): Free all strings used as dummy
6526 variables; fixes memory leak.
6528 * src/eval.h src/eval.c: New function free_at() that frees all strings
6529 stored in an old action table so that there is no memory leak when the
6532 * src/command.c (define): Free old action table if a function is
6533 redefined; fixes memory leak.
6535 * src/parse.c (temp_at parse_primary_expression): Recode to use new
6538 2005-07-08 Ethan Merritt <merritt@u.washington.edu>
6540 * docs/gnuplot.doc src/internal.c (f_range f_strstrt)
6541 src/parse.c (parse_primary_expression):
6543 Switch convention of substring indexing from C-like (first character has
6544 index 0) to Fortran-like (first character has index 1). This makes the
6545 routines strstrt() and word() consistent with each other, and makes the
6546 range specifier form string[beg:end] consistent with both of them.
6548 * demo/stringvar.dem: Expand demo to illustrate use of the substring
6549 operator and the various string string functions.
6551 2005-07-07 Ethan Merritt <merritt@u.washington.edu>
6553 * src/gp_types.h: Provide a pseudo-plot type NODATA to indicate that
6554 this plot is being skipped because the datafile was empty.
6556 * src/plot2d.c (eval_plots): When no valid points are found in a data
6557 file, issue a warning message, mark the current plot as NODATA, but then
6558 process the rest of the command line as normal rather than bailing to
6559 command line. This is a return to the behavior of 3.7.2, except that now
6560 there is an explicit warning message for each empty file. If other code
6561 sections code are sensitive to lack of data, they can test for NODATA.
6562 Addresses enhancement requests #1063873 and #1204125.
6564 2005-07-06 Ethan Merritt <merritt@u.washington.edu>
6566 * src/internal.c (f_sprintf): Switch from using a fixed length output
6567 buffer to a dynamically-allocated one. The string output by sprintf is
6568 no longer limited to 80 characters.
6570 * demo/stringvar.dem: Test dynamic extension of sprintf output buffer.
6572 * src/datafile.c (df_readline): Only call add_key_entry() if the current
6573 plot is really a histogram; otherwise specifying 'using key(<n>)'
6574 causes a segfault on non-histogram plots.
6576 * docs/gnuplot.doc: Clarify the method of auto-generating key titles
6577 and tic labels for columnstacked histogram style.
6579 2005-07-03 Juergen Wieferink <wieferink@freenet.de>
6581 * src/command.c (system_command): Simplify code by using
6582 try_to_get_string() to extract the command string from input line.
6584 * docs/gnuplot.doc: Fix typo in the documentation for words(string).
6585 Add mention that `set style fill` applies to filledcurves.
6587 2005-07-03 James R. Van Zandt <jrv@debian.org>
6589 * term/gd.trm: Document "set output '| display png:-'".
6591 2005-07-02 Ethan Merritt <merritt@u.washington.edu>
6593 * src/eval.c src/internal.c src/internal.h src/parse.c:
6594 New string-related functions:
6595 + words("string") returns the number of whitespace-separated words in
6596 the string. For example, words("A B C D") = 4
6597 + word("string",N) returns the Nth word in the string. For example,
6598 word("A B C D",3) = "C"
6600 * docs/gnuplot.doc: Document new functions word() and words().
6602 2005-06-29 Ethan Merritt <merritt@u.washington.edu>
6604 * src/util.c src/util.h: #define isstringvalue(c_token) to include both
6605 isstring() and, if enabled, isstringvar().
6607 * src/plot2d.c src/plot3d.c src/set.c term/emf.trm term/gd.trm
6608 term/post.trm term/tgif.trm term/x11.trm: Modify all callers of
6609 isstring+isstringvar to either use the new combined routine or to call
6610 try_to_get_string() directly and handle both string and non-string
6613 * src/axis.h: And one caller was hiding in a macro.
6615 Fixes the following bugs:
6616 + `plot func(x), FILENAME` gave an error
6617 + `set term pslatex font FONTNAME` should not have been legal
6618 + `set title "foo" -1,-1` (old style syntax with no "offset" keyword)
6619 caused a parsing error
6620 + fixes order-dependence of options to `set term emf`
6622 There are 60 odd instances of isstring() remaining, many of which are
6623 tests for format strings (e.g. `set format xy "format_string"`).
6625 2005-06-28 Ethan Merritt <merritt@u.washington.edu>
6627 * docs/checkdoc.c: Allow for lines beginning with '=' in gnuplot.doc
6628 (now used to indicated an explicit index entry).
6630 2005-06-27 Shigeharu Takeno <shige@iee.niit.ac.jp>
6632 * src/set.c (parse_label_options): Allow string variable or expression
6635 2005-06-27 Ethan Merritt <merritt@u.washington.edu>
6637 * src/internal.c (f_calln): Prevent buffer overflow if more parameters
6638 than expected are passed to a function.
6640 2005-06-26 Petr Mikulik <mikulik@physics.muni.cz>
6642 * docs/Makefile.in: Replace "sort" by "LC_ALL=C sort" when building
6643 allterm.h to avoid localized sorting.
6645 2005-06-24 Petr Mikulik <mikulik@physics.muni.cz>
6647 * docs/gnuplot.doc: Rewritten section for "help exit".
6649 2005-06-22 Ethan Merritt <merritt@u.washington.edu>
6651 * src/eval.c src/internal.h src/internal.c (f_strstrt): New built-in
6652 string function that searches for a substring within a longer string.
6653 Equivalent to C library function strstr(haystack,needle) except that
6654 rather than returning a pointer, it returns an index. Example:
6655 n = strstrt("haystaneedleck","needle")
6658 * demo/stringvar.dem docs/gnuplot.doc: Document and add to string demo.
6660 * NEWS: Update list of new features.
6662 2005-06-20 Ethan Merritt <merritt@u.washington.edu>
6664 * src/set.c (set_xyzlabel): Allow string variable or expression for
6665 font name. This is a variant of a patch from Shigeharu TAKENO.
6667 * src/plot2d.c (get_data histogram_range_fiddling): Clean up histogram
6668 code dealing with missing data or blank lines. Fixes an autoscaling bug
6669 if a data file ends with blank lines.
6671 2005-06-19 Ethan Merritt <merritt@u.washington.edu>
6673 * docs/gnuplot.doc src src/set.c (set_decimalsign): New command option
6674 `set decimalsign {locale {"locale_spec"}}`
6675 takes the decimal sign character from the locale specified for the
6676 locale "locale_spec" or from the locale specified in the enviromental
6677 variables LC_NUMERIC, LC_ALL, or LANG.
6679 * src/save.c (save_set_all): Save the current locale for LC_NUMERIC
6680 as well as the actual current value of decimalsign.
6682 * src/show.c (num_to_str) src/util.c (gprintf): Allow for the
6683 possibility that the current decimal sign is a comma rather than a dot.
6685 * src/variable.c (locale_handler): Expand output by `show locale` to
6686 show the current values of LC_NUMERIC LC_CTYPE and LC_TIME.
6688 * src/unset.c (unset_decimalsign): If the decimalsign is reset using
6689 `unset decimalsign`, then set the internal locale to C.
6691 2005-06-18 Harald Harders <h.harders@tu-bs.de>
6693 * docs/gnuplot.doc: Revise the section on "set arrow".
6695 2005-06-16 Harald Harders <h.harders@tu-bs.de>
6697 * docs/gnuplot.doc: Document `set style line <n> linecolor <colorspec>`
6699 2005-06-15 Ethan Merritt <merritt@u.washington.edu>
6701 * demo/stringvar.dem docs/gnuplot.doc src/eval.c: Rename substring
6702 built-in function to substr(string,beg,end).
6704 2005-01-15 Bastian Maerkisch <bmaerkisch@web.de>
6706 * term/pm.trm src/os2/gclient.c src/os/pm_msgs.h: Move definition of
6707 message codes for communication between gnuplot (pm.trm) and gnupmdrv
6708 (gclient.c) to a new separate file pm_msgs.h. Replace hard-wired codes
6709 in gclient.c by symbolic names.
6711 * term/pm.trm (PM_set_font): Fix font selection for pm terminal in case
6712 of empty font string.
6714 * src/plot.c (RexxInterface): Replace input_line[] by gp_input_line[]
6715 in code sections which are only compiled on OS/2.
6717 * src/os2/gclient.c (ParseText): Fix super- and subscripts in enhanced
6718 mode of the pm terminal.
6720 2005-06-14 Ethan Merritt <merritt@u.washington.edu>
6722 New functions related to string variables:
6723 sub = "ABCDEF"[beg:end]
6724 sub = substring("ABCDEF",beg,end)
6725 len = strlen("ABCDEF")
6727 * src/parse.c (parse_primary_expression): Check for a postfixed
6728 range specifier at the end of parsing an expression.
6730 * src/internal.c (f_range) src/internal.h: New internal function
6731 f_range() that applies a range specifier to a string in order to
6732 extract a substring. Used both by substring() and by [*:*]
6734 * src/eval.c src/eval.h: Define an index code for the internal
6735 function f_range(). Make it accessible also as a function
6736 substring("string",beg,end). Also define a function strlen("string").
6738 * demo/stringvar.dem demo/all.dem docs/gnuplot.doc:
6739 Document and provide examples of substring syntax.
6740 Add string variable demo to all.dem
6742 2005-06-13 Frank Maas / Ethan Merritt
6744 * docs/gnuplot.doc: Clarify histogram documentation to explain that
6745 histograms always use x1 axis coordinates, but other plot elements on
6746 the same plot may freely use either x1 or x2.
6748 2005-06-13 KITA Toshihiro <t-kita@cc.kumamoto-u.ac.jp>
6750 * docs/gnuplot.doc: Update `set xlabel` example to use the `offset`
6753 2005-06-04 Juergen Wieferink <wieferink@freenet.de>
6755 * src/parse.c eval.c eval.h internal.c command.c set.c:
6756 Code clean up: replace explicit test-and-free of string values with a
6757 call to gpfree_string().
6759 * src/datafile.c (df_open): Clean up parsing of data file name,
6760 using generic functions try_to_get_string() and gpfree_string().
6762 2005-06-04 Ethan Merritt <merritt@u.washington.edu>
6764 * src/eval.c src/eval.h src/show.c src/setshow.h: Move the routine
6765 disp_value() and its helper num_to_str() from eval.c to show.c. This
6766 reduces the need for mutual cross-referenced #includes, and anyway the
6767 routine belongs in either show.c or save.c because that's what it does.
6769 2005-06-04 Juergen Wieferink <wieferink@freenet.de>
6771 * src/show.c (disp_value) src/setshow.h: Introduce an additional
6772 parameter to disp_value() that controls whether or not quotes are
6773 printed around strings on output. This allows simplification of the
6774 code at all call sites.
6776 * src/command.c (print_command) src/internal.c (DEBUG code only)
6777 save.c (save_variables__sum) show.c (disp_at show_variables):
6778 Modify call sites of disp_value() to explicitly request quoted strings
6781 2005-06-02 Ethan Merritt <merritt@u.washington.edu>
6783 * docs/README docs/titlepag.tex docs/doc2tex.c docs/doc2texi.el:
6785 Add a mechanism to auto-generate an index for the documentation via the
6786 TeX package "makeindex". All TeX-derived documentation formats will
6787 include the index. Juergen Wieferink has similarly modified the
6788 generation of gnuplot.info. A keyword is inserted in the index if
6789 it is found on a line of gnuplot.doc beginning with with '?' or '=',
6790 or if it appears as the final word of a phrase wrapped in backtics.
6791 This latter rule picks up cross-reference sites, but may be disabled
6792 by compiling doc2tex with -DNO_CROSSREFS.
6794 * docs/doc2.gih.c docs/doc2hlp.c docs/doc2ipf.c docs/doc2ms.c docs/doc2rnh.c
6795 docs/doc2rtf.c: Ignore leading '=' character in input stream. These
6796 conversion tools do not know how to generate an index.
6798 * docs/gnuplot.doc term/gd.trm term/x11.trm: Add some explicit indexing
6799 entries (keywords with a '=' in the first column of the line).
6801 * docs/Makefile.in: Switch generation of html documentation to use
6802 latex2html toolchain rather than going via gnuplot.texi
6804 2005-06-02 Juergen Wieferink <wieferink@freenet.de>
6806 * src/eval.c (Gstring gpfree_string) src/eval.h: Separate the freeing
6807 of an old string variable from the creation of a new one. New function
6810 * src/mouse.c src/internal.c (f_gprintf f_sprintf f_concatenate)
6811 src/command.c (define) src/mouse.c (load_mouse_variables): Convert to
6812 use new gpfree_string() function. Fix memory leaks from re-use of
6813 string variable names.
6815 2005-06-01 Ethan Merritt <merritt@u.washington.edu>
6817 * src/util.c docs/gnuplot.doc src/graphics.c: Update old comments and
6818 documentation; quiet compiler warnings about uninitialized variable.
6820 2005-05-27 Daniel Sebald <daniel.sebald@ieee.org>
6822 * term/post.trm: Fix incorrect fprintf statement that was causing
6825 2005-05-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
6827 * src/gplt_x11.c: Lots of coding style changes, mainly missing
6828 blanks after commas.
6829 (main) [USE_X11_MULTIBYTE]: Reset LC_NUMERIC locale to "C", after
6830 all others have been set to the user's selection for purposes of
6831 multi-byte font support.
6833 2005-05-25 Daniel Sebald <daniel.sebald@ieee.org>
6835 SF Patch [1117060] Mod to post.trm for PostScript Level 1 images.
6837 * term/post.trm: New routine PS_encode_image(), new postscript variable
6838 InterpretLevel1 and some other changes.
6840 2005-05-24 Ethan Merritt <merritt@u.washington.edu>
6842 * src/tables.c: Allow shorthand for "set macros".
6844 * src/term_api.h term/README: Add new terminal flag TERM_NO_OUTPUTFILE.
6846 * src/term.c (term_init): As per discussion on gnuplot-beta, when
6847 changing to a new terminal type, check flags for TERM_NO_OUTPUTFILE
6848 associated with the new type. If present, then close current output
6849 file cleanly rather than reopening and overwriting it.
6852 * term/x11.trm term/win.trm term/pm.trm term/be.trm term/aquaterm.trm:
6853 Mark terminal as TERM_NO_OUTPUTFILE.
6856 2005-05-23 Ethan Merritt <merritt@u.washington.edu>
6858 * term/estimate.trm (ENHest_put_text): Track estimated limits on
6859 string y extent also.
6861 2005-05-22 Peter Weilbacher <paepse@users.sourceforge.net>
6863 * src/gp_hist.h src/readline.c: Fix conditional dependencies on
6864 READLINE and HAVE_LIBREADLINE so that ./configure + build is
6865 clean with all three readline options.
6867 2005-05-22 Ethan Merritt <merritt@u.washington.edu>
6869 * term/gd.trm term/mif.trm term/pdf.trm: Code cleanup - remove static
6870 initializers from the TERM_PROTO code block. ggi.trm has these also,
6871 but I can't test for correctness after a change so I don't want to
6872 change it. Remove obsolete comments.
6874 2005-05-20 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
6876 * src/util.c (PRINT_MESSAGE_TO_STDERR): New macro: invokes printf
6877 while protecting itself from current_prompt == NULL.
6878 (os_error, int_error, int_warn): Use new macro.
6880 2005-05-20 Peter Weilbacher <paepse@users.sourceforge.net>
6882 SF Patch [981476] Get history functions working with GNU readline
6884 * command.c (history_command): Let the "history" command be available
6885 also for GNU readline, i.e. HAVE_LIBREADLINE.
6887 * history.c: Make routines for GNU readline compatible to those of
6890 2005-05-19 Ethan Merritt <merritt@u.washington.edu>
6892 * src/datafile.c (df_readline) src/gadgets.h src/save.c (save_set_all)
6893 src/set.c (set_bars parse_histogramstyle) src/show.c (show_histogram)
6894 src/plot2d.c (get_data histogram_range_fiddling)
6895 src/graphics.c (do_plot plot_bars plot_boxes): New histogram plot mode
6897 set style histogram errorbars {gap <g>} {linewidth {lw}}
6899 Identical to 'set style histogram clustered' except that a second
6900 column of input data (required) is used to generate error bars at the
6901 top of each box belonging to the histogram.
6903 * docs/gnuplot.doc: Document the addition of a new histogram
6904 plot mode and associated options for 'set bars'.
6906 2005-05-18 Ethan Merritt <merritt@u.washington.edu>
6908 * src/set.c (set_allzeroaxis): Fix parsing error (bug #1204444).
6910 2005-05-16 Ethan Merritt <merritt@u.washington.edu>
6912 * src/plot3d.c (eval_3dplots): Prevent parser from getting into an
6913 infinite loop when parsing 'splot with vectors' and no additional
6914 options (bug #1203139).
6916 * src/graph3d.c (do_3dplot): Show key sample for 'splot with vectors'.
6918 2005-05-15 Ethan Merritt <merritt@u.washington.edu>
6920 * src/set.c (set_terminal): That last change wasn't popular.
6921 Instead, provide additional (but not complete) backward
6922 compatibility by doing an implicit "unset table" whenever the
6923 terminal is changed.
6925 2005-05-14 Ethan Merritt <merritt@u.washington.edu>
6927 * src/set.c (set_terminal): Give up on trying to provide backward
6928 compatibility for the old 'set term table' command; just issue a
6929 warning and leave the current terminal unchanged.
6931 2005-05-13 Ethan Merritt <merritt@u.washington.edu>
6933 * src/term.c (ignore_enhanced): Force a return to the default font.
6936 * term/README: Document the fact that term->set_font("") is expected
6937 to restore the terminal's default font. This was already true, but
6938 not mentioned in README.
6940 2005-05-13 Petr Mikulik <mikulik@physics.muni.cz>
6942 * term/fig.trm (FIG_linetype): Use the postscript sequence of linetype
6945 2005-05-11 Ethan Merritt <merritt@u.washington.edu>
6947 * src/gplt_x11.c (exec_cmd): Reorder variable declarations to allow
6948 building without binary-polygon support.
6950 2005-05-09 Ethan Merritt <merritt@u.washington.edu>
6952 * src/gplt_x11.c: Rename static arrays Class[] -> X_Class[] and
6953 Name[] -> X_Name[] to avoid conflict with gcc 4 build environment
6954 under OSX 10.4 as reported by Per Persson.
6956 * docs/gnuplot.doc: Correct typo referring to 'set pause mouse'.
6958 * term/post.trm term/pslatex.trm (PSTEX_text): Allow postscript-based
6959 terminals to use fractional font sizes; change ps_fontsize from int to
6960 float, and change relevant format statements from %d to %g.
6962 2005-05-07 Ethan Merritt <merritt@u.washington.edu>
6964 * src/unset.c (reset_command): Don't include macro setting in general
6965 `reset`; macro expansion is more likely to be chosen per-input-file
6968 2005-05-06 Ethan Merritt <merritt@u.washington.edu>
6970 * src/plot2d.c (get_data histogram_range_fiddling): Treat all boxwidths
6971 as absolute when in HISTOGRAM plot mode. Be more thorough in checking
6972 for histogram entries that extend the X range in auto-scale mode.
6973 Fixes bugs reported by Andrew J Caird.
6975 2005-05-05 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
6977 * docs/gnuplot.doc (timecolumn): New documentation entry for this
6978 old "secret" function.
6980 * src/datafile.c (f_timecolumn): Major brush-over, and lots of
6981 comments explaining just how broken this function currently is.
6983 2005-05-02 Ethan Merritt <merritt@u.washington.edu>
6985 * src/util.c (isstringvar) src/util.h: Have this function always
6986 return FALSE if gnuplot is configured with --disable-stringvariables.
6988 * term/tgif.trm (TGIF_options): Accept string variable for font name.
6990 * src/hidden3d.c (build_networks): If vertex has previously been flagged
6991 as invalid, do not pass it on for further processing.

6999 * term/gd.trm (PNG_options): Accept string variable for font name.
7001 * src/plot2d.c (get_data eval_plots): If the x-axis is in log mode,
7002 treat boxwidth as a constant visual width rather than as a constant
7003 number of units along x, which would produce narrower boxes as x
7004 increases. Issue an error message if the x-axis is in log mode
7005 when the plot style is histograms.
7007 * docs/gnuplot.doc: Document behaviour of 'set boxwidth' for log axes.
7009 * docs/gnuplot.doc term/x11.trm term/post.trm: Clean up line length
7010 and other issues that cause errors during creation of TeX docs.
7012 2005-04-29 Petr Mikulik <mikulik@physics.muni.cz>
7014 * pm3d.c (set_plot_with_palette): Fix for 'splot x, y with pm3d'.
7016 2005-04-28 Ethan Merritt <merritt@u.washington.edu>
7018 * term/x11.trm (X11_options): Accept string variables for terminal
7019 options 'font <foo>' and 'title <bar>'.
7021 * term/post.trm (PS_options) term/emf.trm (EMF_options):
7022 Accept string variable for font name.

7026 * config/makefile.wc: Update for more Watcom-like usage of tools.
7028 * config/config.wc: New file. Promised long ago, when I added
7029 makefile.wc, finally got round to doing it.
7031 * config/config.oww, config/makefile.oww: Rewrite for more
7032 features and more Watcom-like usage of tools.

7051 * src/win/wgraph.c (drawgraph): Initialize local variable to avoid
7054 * src/history.c (write_history_n): Only define local is_pipe if
7055 PIPES enabled. Avoids a -Wunused.
7057 * src/command.c (winsystem): Define this function only if
7058 USE_OWN_WINSYSTEM_FUNCTION is set. Removes a -Wunused.

7069 2005-04-23 Ethan Merritt <merritt@u.washington.edu>
7071 Bug fix: Do not apply axis mapping (e.g. log scale) twice to the
7072 label coordinates in plot style 'with labels'.
7074 * src/gadgets.h: Define a new "layer" LAYER_PLOTLABELS, which
7075 allows the label-processing code to distinguish labels whose coords
7076 have already been axis-mapped from those where they have not.
7078 * src/graphics.c (place_labels do_plot) src/plot2d.c (eval_plots)
7079 src/graph3d.c (place_labels3d do_3dplot) src/plot3d.c (eval_3dplots):
7080 Mark the labels making up a 'with labels' plot as belonging to
7081 LAYER_PLOTLABELS rather than to front or back layers.
7083 * src/gplt_x11.c (exec_cmd): When setting a new font, set it for
7084 both the normal and pm3d graphics contexts.

7125 * docs/xref.c (xmalloc): Fixed missing return from non-void
7128 2005-04-21 Ethan Merritt <merritt@u.washington.edu>
7130 * src/command.c (pause_command) src/command.h docs/gnuplot.doc:
7131 Modify syntax of pause mouse command:
7132 pause mouse {<end_condition>}{,<end_condition>}... {"prompt"}
7133 where <end_condition> is one of
7134 keystroke, button1, button2, button3, any
7136 * src/mouse.c (event_keypress event_buttonpress event_bottonrelease

7138 Test individually for specific end conditions for `pause mouse`.
7140 2005-04-18 Ethan Merritt <merritt@u.washington.edu>
7142 * src/save.c (save_linetype) src/save.h src/show.c: Code cleanup.
7143 Provide a single routine to handle all the places that dump information
7144 from a structure of type lp_style_type. This cleans up 9 call sites in
7145 save.c and 9 more in show.c, many of which were not handling the recent
7146 extensions to line types in general. The grid linetypes were not being
7149 * src/set.c (set_key): Fix parsing bug that caused next item after
7150 'set key title "Foo"' to be ignored.
7152 * src/graphics.c (boundary): Fix for bug #1184989. Explicitly test for
7153 absence of any plot titles when sizing the key (avoid divide-by-zero).
7155 2005-04-18 Petr Mikulik <mikulik@physics.muni.cz>
7157 * term/fig.trm (FIG_set_color): Support for "textcolor lt".

7161 * term/pslatex.trm: Clean up macro definitions written to
7162 output file of 'set term epslatex'.

7172 src/graphics.c (do_plot) src/save.c (save_set_all)
7173 src/set.c (set_border) src/show.c (show_border):
7174 Make parsing of 'set border' options independent of their order.
7175 New option 'set border {front|back}'.
7177 2005-04-11 Ethan Merritt <merritt@u.washington.edu>
7179 * term/post.trm: Fix for bug #1180853, arrowheads drawn in wrong
7180 color if the arrow body has a specific line style or color.
7182 2005-04-10 Ethan Merritt <merritt@u.washington.edu>
7184 * demo/histograms.dem: Correct behaviour of the demo depended
7185 on a bug in the xrange code. Now that the bug is fixed (26-Mar-05)
7186 the demo needs to be fixed also (don't set xrange to [0:*]).
7188 2005-04-08 Ethan Merritt <merritt@u.washington.edu>
7190 * Makefile.am configure.in: Continued attempts to make configure
7191 ignore lisp files altogether when --without-lisp-files is chosen.
7192 In this case skip ./lisp subdirectory during 'make' recursion.
7194 2005-04-08 Petr Mikulik <mikulik@physics.muni.cz>
7196 * docs/gnuplot.doc: Improved 'help cbrange'.
7198 2005-04-06 Petr Mikulik <mikulik@physics.muni.cz>
7200 * src/pm3d.c (set_plot_with_palette): Do not set the flag for displaying
7201 colorbox for 'splot ... with rgbimage'.
7203 2005-04-06 Ethan Merritt <merritt@u.washington.edu>
7205 * term/README: Show call order of enhanced text mode entry points
7206 and mention that 'set termoption' calls into term->options().
7208 2005-04-03 Ethan Merritt <merritt@u.washington.edu>
7210 * src/set.c: Allow 'set termoption delay <n>' to change the interframe
7211 gap of a gif animation in progress.
7213 * term/gd.trm (PNG_options):
7214 Add gif animation option 'loop <repeatcount>'. Protect current animation
7215 state from being reset by a 'set termoption' command, but alow the frame
7216 delay to be changed. List animation options in terminal options string.
7218 2005-04-03 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7220 * docs/gnuplot.doc: Remove blanks from whitespace-only lines.
7222 2005-04-01 Juergen Wieferink <wieferink@freenet.de>
7224 * docs/doc2tex.c: Handle levels 5 and 6 of documentation text as
7225 paragraph and subparagraph, respectively.
7227 2005-04-01 Ethan Merritt <merritt@u.washington.edu>
7229 * docs/gnuplot.doc: Add help keyword for 'newhistogram'.
7231 * configure.in: If the user configures --without-lisp-files then
7232 do not try to run configure in the lisp subdirectory.
7234 2005-03-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7236 * src/gplt_x11.c (process_event) [!USE_MOUSE]: don't refer to
7237 objects and functions not defined in this case.
7239 * src/plot3d.c (eval_3dplots) [!GP_STRING_VARS]: Don't call
7240 isstringvar() if feature disabled.
7242 * src/plot2d.c (eval_plots) [!GP_STRING_VARS]: Likewise.
7244 * src/show.c (show_command): Fix display of 'zeroaxis' settings
7245 reported by error message.
7247 * src/set.c (set_command): Likewise.
7249 * src/unset.c (unset_command): Likewise.
7251 2005-03-29 Ethan Merritt <merritt@u.washington.edu>
7253 * demo/candlesticks.dem: Add demo of whiskerbars option.
7255 2005-03-29 Petr Mikulik <mikulik@physics.muni.cz>
7257 * NEWS docs/gnuplot.doc src/plot3d.c src/pm3d.c src/pm3d.h src/save.c
7258 src/set.c src/show.c src/unset.c: Let pm3d drawing be always available
7259 without prior "set pm3d": now you can "splot x*y with pm3d" without
7260 prior "set pm3d". The "explicit" be the default pm3d value after reset.
7261 For compatibility (historical) reasons (color filled pm3d plot
7262 combined with mesh line plot): commands "set pm3d;" and "set pm3d at X
7263 other_opts;" switch pm3d to "implicit". No change for "set pm3d map".
7265 2005-03-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7267 * src/pm3d.c (set_plot_with_palette): Add a missing #ifdef
7268 WITH_IMAGE conditional.
7270 2005-03-27 Ethan Merritt <merritt@u.washington.edu>
7272 * NEWS configure.in term/gd.trm: Allow storage of a sequence of plots
7273 into a single animated gif file.
7274 set term gif animate {delay <time>} {nooptimize}
7275 Requires libgd version 2.0.29 or better (2.0.33 is recommended).
7277 * src/plot2d.c (histogram_range_fiddling): Make it more obvious in the
7278 code that histograms always use FIRST_X_AXIS.
7280 2005-03-26 Ethan Merritt <merritt@u.washington.edu>
7282 SourceForge patch #1090199 "Extend hotkeys to all open plot windows"
7284 Implement new option "bind all <key> <command>" that extends
7285 hotkeys to inactive plot windows in addition to the active window.
7286 The code is general, although currently only the x11 terminal
7287 tracks the ID of multiple windows in order to report who is who.
7289 * src/command.c (bind_command): New keyword "bind {all$windows} ..."
7291 * src/gpexecute.c (gp_exec_event) src/gpexecute.h:
7292 New parameter holds ID of window from which this event was triggered.
7294 * src/gplt_x11.c (process_event): Pass ID of originating window to
7295 gp_exec_event() along with the x,y coordinates and keystroke.
7296 Distinguish between active and inactive window by using event code
7297 GE_keypress or GE_keypress_old. You get the window ID in either case.
7299 * src/mousecmn.h: Add new field int winid to struct gp_event_t.
7301 * src/mouse.c src/mouse.h:
7302 Add new TBOOLEAN allwindows to the bind_t structure.
7303 New routine bind_all() sets this flag from "bind all <foo> <baz>".
7304 Teach event_keypress() to distinguish between keystrokes from active
7305 or inactive windows, and to load originating window ID into udv
7306 MOUSE_KEY_WINDOW so that it is visible to user-defined commands.
7308 * src/os2/gclient.c src/win/wgraph.c:
7309 Add extra parameter for window ID in all calls to gp_exec_event().
7311 * docs/gnuplot.doc: Document new command option "bind all <key>
7314 * src/mouse.c (event_buttonpress) term/x11.trm (X11_waitforinput):
7315 Do not terminate "pause mouse key" on mouse button clicks. This allows
7316 zoom, select, and other mouse-click operations during the pause.

7340 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots): Don't increment
7341 the default line/point properties for line/point plots if this_plot is
7342 an (rgb)image (the same is already happening for pm3d plots).
7343 Otherwise, "splot 'a.dat' with image,x*y with line" and "... x*y w line,
7344 'a.dat' with image" draw surface x*y in different colours.

7348 * docs/gnuplot.doc src/set.c (set_table) src/unset.c (unset_table)
7349 src/tables.h src/tables.c:
7351 set table {"outfile"}
7353 These replace the old 'set term table', which never worked in general.
7355 * src/gadgets.c src/gadgets.h: TBOOLEAM table_mode and output file
7356 pointer table_outfile shared by plot2d and plot3d in table mode.
7358 * src/plot2d.c (print_table) src/plot3d.c (print_3dtable):
7359 If table_mode is set we send tabular output to table_outfile, if it was
7360 specified, otherwise send it to gpoutfile.
7362 * src/set.c (set_terminal): Allow 'set term table' as a special case
7363 backwards compatibility option. It doesn't work all that well, but then
7364 again the original didn't work either.
7366 * demo/all.dem demo/vector.dem: Rework vector.dem to use the new
7367 commands. This makes it safe to include as part of all.dem because
7368 unlike the old 'set term table' it doesn't trash the current state of
7371 * src/term.c src/term.h: Remove table.trm from the list of terminals.
7373 2005-03-24 Ethan Merritt <merritt@u.washington.edu>
7375 * term/post.trm: Initialize the data structure pointer ps_params to
7376 point to the normal postscript mode values; without this, setting
7377 environmental variable GNUTERM to any of the PostScript terminal modes
7378 will cause a segfault on entry.
7380 2005-03-23 Aapo Lankinen <aapo.lankinen@gmail.com>

7399 for data files with multiple surfaces.
7401 2005-03-18 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7403 * docs/gnuplot.doc (set title): Add missing keyword "font".
7405 2005-03-17 Petr Mikulik <mikulik@physics.muni.cz>
7407 * src/graph3d.c (do_3dplot): Fix 'set pm3d at X; splot...with pm3d at Y'
7408 for data files with multiple surfaces.
7410 2005-03-16 Ethan Merritt <merritt@u.washington.edu>
7412 * src/datafile.c (df_readline): Allow for embedded whitespace in the
7413 output of a string-valued expression inside a "using" spec.
7415 * src/graph3d.c (plot3d_points_pm3d plot3d_points): Remove routine
7416 plot3d_points_pm3d, and handle pm3d-colored points in plot3d_points
7417 instead. This removes any special drawing order for the points.
7419 2005-03-16 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7421 * src/axis.h (AXIS_ACTUAL_MAX, AXIS_ACTUAL_MIN): New macros to
7422 access range endpoints correctly, even if 'set view map' has mixed
7423 up the internal status.
7425 * src/util3d.c (IN_AXIS_RANGE): New macro, equivalent to calling
7426 inrange() with the two endpoints of any given axis' range. Makes
7427 code a bit more readable.
7428 (edge3d_intersect): New local macros INTERSECT_PLANE,
7429 INTERSECT_DIAG to centralize lots of very similar code blocks.
7430 Implement fix for clipping of -VERYLARGE points in the presence of
7431 'set view map' reversed ranges, by using new axis.h macros.
7432 (two_edge3d_intersect): Use new macro IN_AXIS_RANGE, reindent, for
7435 2005-03-15 Petr Mikulik <mikulik@physics.muni.cz>
7437 * src/pm3d.c (set_plot_with_palette): Fix displaying colorbox also for
7438 'splot ... with image'.
7440 2005-03-14 Petr Mikulik <mikulik@physics.muni.cz>
7442 * src/pm3d.c (set_plot_with_palette): Fix displaying colorbox for 'plot
7445 2005-03-12 Ethan Merritt <merritt@u.washington.edu>
7447 * src/plot2d.c (eval_plots): Fix bug in initialization order that
7448 prevented "set style data labels" from working in 2D plots.
7450 2005-03-09 Ethan Merritt <merritt@u.washington.edu>
7452 * term/emf.trm term/gd.trm term/pdf.trm term/pm.trm term/post.trm
7453 term/svg.trm term/x11.trm src/gplt_x11.c src/gplt_x11.h:
7454 Modify term->set_color() to handle colorspec type LC_LT.
7455 This has the effect of changing the current line color to that of
7456 default linetype <lc> without changing any other line properties.
7458 * misc.c (lp_parse) save.c (save_set_all) show.c (show_linestyle)
7460 Allow line color {linecolor|lc} to be specified separately from the
7461 linetype. For example, this command will give a dashed black line:
7462 set style line 1 lt 2 lc -1
7463 and the following will give a dashed gold line:
7464 plot sin(x) with lines lt 2 lc rgb "gold"
7466 * demo/dashcolor.dem: Demo of choosing both linetype (dot/dash pattern)
7467 and linecolor separately.
7469 * src/misc.c (arrow_parse): Bugfix: Keep current linetype as the default
7470 when parsing possible additional line style options.
7472 2005-03-06 Ethan Merritt <merritt@u.washington.edu>
7474 * src/datafile.c (df_readline) src/misc.c (parse_colorspec):
7475 Clean up code to remove the remaining 2 compiler warnings in current cvs.
7477 2005-03-05 Harald Harders <h.harders@tu-bs.de>
7479 * term/post.trm (PS_options): Patch #1121971. Avoid external
7480 processing of escaped characters in the epslatex header string.
7482 2005-03-05 Ethan Merritt <merritt@u.washington.edu>
7484 * src/datafile.c (df_readline): Plug a memory leak caused by evaluating
7485 a string-valued expression inside a "using" specification.
7487 * configure.in /config/config.amg /config/config.cyg /config/config.mgw
7488 /config/config.os2 /src/eval.c /src/eval.h /src/internal.c
7489 /src/internal.h /src/parse.c /src/standard.c /src/standard.h:
7491 Remove configuration option --disable-defined-var.
7492 Remove the #ifdef GP_ISVAR ... #endif bracketing the corresponding code.
7494 * term/cgm.trm (CGM_linecolor): Force all line and point color requests
7495 to black if the terminal is in monochrome mode. Bug fix courtesy of
7496 N Matsuda (Tokyo Denki University).
7498 2005-03-04 Ethan Merritt <merritt@u.washington.edu>
7500 * src/datafile.c: Introduce a defined constant MAX_TOKEN_LENGTH
7501 rather than trusting multiple call sites to declare consistently
7502 sized character arrays.
7504 * src/eval.c src/datafile.h src/datafile.c docs/gnuplot.doc:
7505 New internal function f_stringcolumn() usable only inside a "using"
7506 specification; pushes the content of a data column onto the evaluation
7507 stack as a string variable.
7509 plot 'foo' using (stringcolumn(1) eq "baz" ? column(2) : column(3))
7511 * src/datafile.c (df_readline df_3dmatrix df_readbinary):
7512 Set a flag to indicate that we are in the process of evaluating a
7513 "using" specification.
7515 * src/datafile.c (f_column f_timecolumn f_stringcolumn):
7516 Report an error if any of the <xxx>column() functions are called
7517 outside the context of a "using" specification.
7519 * configure.in: Remove the "EXPERIMENTAL" warning from the histogram
7520 and datastrings options; they've had 2 years of testing.
7522 2005-03-02 Ethan Merritt <merritt@u.washington.edu>
7524 * src/unset.c (unset_historysize): Rearrange #ifdefs for GNUPLOT_HISTORY
7525 to prevent compiler warnings about unused function definitions.
7527 * src/term.h term/post.h term/post.trm: Introduce a statement
7528 '#define PSLATEX_DRIVER' into post.h that controls whether or not the
7529 pslatex/epslatex terminal code is built. Add #ifdef PSLATEX_DRIVER
7530 in appropriate places. Without this it was impossible to build gnuplot
7531 with post.trm but not pslatex.trm.
7533 * src/term.h: Remove aed.trm and tek.trm from SHORT_TERMLIST set of
7534 terminals, but add estimate.trm if it is enabled.
7536 * configure.in src/graphics.c src/plot2d.c src/save.c src/set.c
7537 src/show.c src/unset.c src/plot2d.h:
7539 Remove configuration option --disable-relative-boxwidth.
7540 Remove the #ifdef USE_ULIG_RELATIVE_BOXWIDTH ... #endif brackets around
7541 code that implements it.
7543 * config/config.amg config/config.cyg config/config.mgw config/config.nt
7544 config/config.os2 configure.in src/bitmap.c src/datafile.c src/gadgets.c

7552 Remove the #ifdef USE_ULIG_FILLEDBOXES ... #endif brackets around code
7555 2005-02-28 Ethan Merritt <merritt@u.washington.edu>
7557 * term/pslatex.trm: EPSLATEX_set_color must be protected by #ifdef PM3D.
7559 2005-02-26 Ethan Merritt <merritt@u.washington.edu>
7561 * src/pm3d.c (set_plot_with_palette): Don't trigger display of the
7562 colorbox in 2D plots just because an explicit line color was set.
7564 * misc.c (parse_fillstyle): accept full keyword "fillstyle" in addition
7567 2005-02-24 Ethan Merritt <merritt@u.washington.edu>
7569 * src/graphics.c(plot_c_bars) src/plot2d.c(eval_plots) docs/gnuplot.doc:
7570 New keyword '... with candlesticks {whiskerbars}' that draws horizontal
7571 crossbars at the top and bottom of the whiskers. This is typical for
7572 box-and-whisker plots. The new keyword is in lieu of adding a
7573 separate "boxplots" plot style (patch #624000).
7575 * src/gplt_x11.c (pr_fastrotate) term/x11.trm (documentation):
7576 The fully general implementation of text rotation added in version 4.0
7577 is *much* slower than it used to be. This patch adds a new X resource
7578 gnuplot*fastrotate: {on|off} that reverts to the faster but imperfect
7579 rotation method. The default is "on", which favors fast rendering at
7580 the cost of possibly corrupting colors of nearby plot elements.
7582 2005-02-22 Ethan Merritt <merritt@u.washington.edu>
7584 * term/x11.trm: Fix botched optimization in previous patch.
7586 2005-02-21 Ethan Merritt <merritt@u.washington.edu>
7588 * term/x11.trm: Implement solid fill rectangles and polygons as a
7589 true solid color, with variable fading toward background color, rather
7590 than approximating by a set of 3 half-tone patterns.
7592 * docs/gnuplot.doc: Explain that for some terminals the size of a "dot"
7593 can be changed using linewidth.
7595 2005-02-18 Ethan Merritt <merritt@u.washington.edu>
7597 * term/pdf.trm: Allow "lw" as an abbreviation for "linewidth"
7598 * term/post.trm: Make dash styles 6 and 7 a bit more distinctive
7599 * term/emf.trm: Add option 'set term emf {linewidth <factor>}'
7600 * term/gd.trm: Solid fill with density < 1 was not working with
7601 rgb colors. Trivial fix.
7602 * term/gd.trm: Add option 'set term ... {linewidth <factor>}';
7603 increase maximum linewidth from 6 to 12
7605 * src/graphics.c (boundary): When estimating the length and height
7606 of xlabel, increase the number of lines by one if we're in enhanced text
7607 mode and there seems to be a subscript. This test can be fooled if the
7608 label has disabled enhanced text processing.
7610 2005-02-18 Petr Mikulik <mikulik@physics.muni.cz>
7612 * src/command.c src/tables.c src/set.c src/unset.c docs/gnuplot.doc: Let
7613 command '{un}set historysize' be always available, but report a
7614 descriptive error if gnuplot has not been configured with GNU readline.
7616 2005-02-17 Ethan Merritt <merritt@u.washington.edu>
7618 * term/pdf.trm: Add terminal options for monochrome and for dashed
7620 set term pdf {mono|color|colour} {solid|dashed {dl dashlength}}
7622 The defaults remain the same as before (color solid). The monochrome
7623 option only affects linetypes; you can still use color explicitly
7624 in filled areas or by using rgb specifications for line styles.
7626 * configure.in: Check for dashed line support in pdflib.
7628 2005-02-16 Harald Harders <h.harders@tu-bs.de>
7630 * term/post.trm: Patch #1122014 "Improve dashed linetypes in Postscript
7633 2005-02-16 Ethan Merritt <merritt@u.washington.edu>
7635 * term/pdf.trm: Correct the driver docs to say font limitations
7636 and font installation instructions must be sought in the pdflib
7639 2005-02-16 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7641 * src/variable.c (loadpath_handler, fontpath_handler):
7642 Re-initialize limit to NULL, too, as p reaches it.
7644 2005-02-15 Ethan Merritt <merritt@u.washington.edu>
7646 * src/save.c src/save.h: New routine save_fillstyle consolidates
7647 redundant code to convert a fill_style_type into a text description.
7649 * src/save.c src/save.h: New routine save_pm3dcolor consolidates
7650 redundant code to convert a colorspec struct into a text description.
7652 * src/save.c (save_set_all save_textcolor) src/show.c (show_linestyle):
7653 Call shared routines rather than duplicate code in-line.
7655 2005-02-14 Ethan Merritt <merritt@u.washington.edu>
7657 * term/pdf.trm (PDF_options PDF_init PDF_dot): Add terminal option
7658 {rounded|butt} exactly parallel to post.trm. The default is butt
7659 ends and mitred line joins. "rounded" switches to rounded ends and
7662 2005-02-14 Petr Mikulik <mikulik@physics.muni.cz>
7664 * src/term.c: Added #include "getcolor.h".
7666 * term/aquaterm.trm term/pdf.trm term/post.trm term/svg.trm: Removed
7667 #include "getcolor.h".
7669 * term/x11.trm: Removed #include "getcolor.h", #ifdef WITH_IMAGE_BUG
7670 #include "graphics.h".
7672 * term/vgagl.trm: Removed #include "driver.h", "pm3d.h", "mousecmn.h".
7674 2005-02-14 Harald Harders <h.harders@tu-bs.de>
7676 * term/pslatex.trm: SourceForge patch #1121972 "Improve input encoding
7677 in epslatex terminal". Added the koi8-u encoding to epslatex. Added
7678 \inputencoding{...} to the output file. This enables the user to use
7679 different input encodings in the surrounding LaTeX file and in the plot.
7680 Added a user-friendly error message if the package graphicx.sty or
7681 graphics.sty is not loaded.
7683 2005-02-13 Harald Harders <h.harders@tu-bs.de>
7685 * term/post.trm term/pslatex.trm: Clean up code in accordance with
7688 2005-02-13 Shigeharu Takeno <shige@iee.niit.ac.jp>
7690 * configure.in: New configuration option --enable-x11-mbfonts
7691 (enabled by default). Interpretation of character encodings
7692 is determined at run time by the LC_CTYPE locale setting.
7694 * src/gplt_x11.c: All calls to x11 font handling routines are
7695 conditionally substituted by the equivalent calls to multi-byte
7696 routines if --enable-x11-mbfonts is configured, and a multi-byte
7697 font has in fact been selected.
7699 * NEWS term/x11.trm: Add documentation that describes the specification
7700 of multi-byte fonts:
7701 set term x11 font "mbfont:<primary font>;<secondary font>"
7702 set label "foo" font "mbfont:<primary font>;<secondary font>"
7704 2005-02-10 Ethan Merritt <merritt@u.washington.edu>
7706 * src/graph3d.c (plot3d_lines_pm3d key_sample_line_pm3d):
7707 If the graph specifies a solid rgb color, fall back to equivalent
7708 single-color routine.
7710 2005-02-11 Petr Mikulik <mikulik@physics.muni.cz>
7712 * src/pm3d.h src/pm3d.c: New global routine is_plot_with_colorbox().
7713 New local variable plot_wants_colorbox. Color box is wanted for all draw
7714 elements using palette except those with TC_RGB.
7716 * src/graphics.c src/graph3d.c: No colorbox for 2D and 3D plots with
7717 elements using "rgbcolor".
7719 2005-02-10 Ethan Merritt <merritt@u.washington.edu>
7721 * src/misc.c (lp_parse): Accept full keyword "rgbcolor" for the line

7734 configuration file for usage with gnuplot-generated LaTeX files
7735 (epslatex terminal with standalone option).
7737 * term/pslatex.trm: Now includes code for all of the following
7739 pslatex: LaTeX with embedded postscript
7740 pstex: plain TeX with embedded postscript
7741 epslatex: LaTeX using \includegraphics, postscript part in an external
7744 * term/epslatex.trm: Removed.

7754 src/misc.c (lp_use_properties) docs/gnuplot.doc:
7755 New internal flag TC_LINESTYLE allows text to take its color from a
7756 line style. For example: set label "foo" textcolor linestyle 2

7765 2005-02-02 Ethan Merritt <merritt@u.washington.edu>
7767 * src/plot3d.c (get_3ddata): Ignore blank lines in data file input to
7768 "splot with vectors".
7770 * src/set.c (set_xyzlabel): Allow set label textcolor rgb <foo>.
7772 * src/gplt_x11.c (display): Always initialize gc_pm3d, in case we need
7773 it to handle individual rgb colors even in the absence of a palette.
7775 * src/save.c (save_textcolor) src/save.h
7776 src/show.c (show_label show_xyzlabel): Export save_textcolor() so
7777 that various "show ...label" routines can use it also. Also fixes
7778 compile error if configured --disable-pm3d.
7780 2005-02-01 Ethan Merritt <merritt@u.washington.edu>
7782 * src/graphics.c (plot_boxes): Plot with boxerrorbars and three columns
7783 of input data hit a rare code path that set the boxwidth wrong in some
7784 cases. Fixes bug #1101409.
7786 2005-02-01 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7788 * src/time.c (xstrftime): Shift reply range of %I and %l time
7789 formats from [0:11] to [1:12].
7791 * docs/gnuplot.doc (time/date specifiers): Fix descriptions of
7792 hour format specifiers (explain 0-filled vs. non-filled default,
7793 give correct output ranges).
7795 2005-02-01 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7797 * src/set.c (set_separator): Replace literal TAB character in
7800 * src/command.c (input_line, input_line_len): Renamed to
7801 gp_input_line and gp_input_line_len respectively, to avoid a
7802 conflict of input_line with a like name non-standard library
7805 * src/command.h: Renamed declarations of these, too.
7807 * all over the place: Renamed usages of these variables. Some
7808 CodeStyle cleanups, while at it.
7810 2005-01-31 Ethan Merritt <merritt@u.washington.edu>
7812 * util.c (getusername): Don't try to free a string pointer that may
7813 have been returned by getenv. Fixes bug #1111804.
7815 2005-01-27 Petr Mikulik <mikulik@physics.muni.cz>
7817 * config/config.mgw: Mingw 2.x does not HAVE_SYS_PARAM_H.
7819 * src/win/wgnuplib.h: Mingw 2.x needs to #define _fstr* functions.
7821 2005-01-26 Petr Mikulik <mikulik@physics.muni.cz>
7823 * demo/pm3d.dem: Remove deprecated references to "set pm3d solid" and

7853 2005-01-11 Ethan Merritt <merritt@u.washington.edu>
7855 * demo/mousevariables.dem demo/keystroke.dem: Fix incorrect termination
7856 logic in the keystroke demo.
7858 * src/graphics.c (boundary): Rather than turning off the key altogether
7859 if the contents seem to be too big to fit, fall back to something half
7860 way plausible and also print an warning message. Fixes (or at least
7861 addresses) bug #1058117.
7863 2005-01-11 Harald Harders <h.harders@tu-bs.de>
7865 Apply updated SourceForge patch #1023783
7867 * configure.in: Check for which libpdf version is present; check
7868 whether <pwd.h> is present.

7871 user name from environment or from passwd file.
7873 * term/pdf.trm (PDF_init) term/post.trm (PS_init): Store username
7874 and other envelope information in the PDF dictionary structure of
7875 the output file. New routine PS_escape_string() to ensure that
7876 character strings entered in the PDF dictionary are legal strings.

7885 term/pslatex.trm: SF patch #1098256 "Introduce struct that takes all
7886 postscript terminal options". This patch introduces the struct
7887 ps_params_t that takes all postscript terminal options, e.g., color,
7888 blacktext, pslevel, rounded, fontsize, ... This is useful when
7889 different terminals share the same portion of code.
7891 2005-01-10 Daniel Sebald <daniel.sebald@ieee.org>
7893 * src/gadgets.c src/gadgets.h src/set.c (set_margin) src/show.c
7894 (show_margin) src/unset.c (unset_margin): Specify and store plot
7895 margins as float rather than int.

7899 * src/graphics.c demo/image.dem: Correct a problem with scaling of
7900 images from 'with image'.
7902 2005-01-08 Ethan Merritt <merritt@u.washington.edu>
7904 * src/term.c (term_start_multiplot): Replace keywords "rowmajor" and
7905 "columnmajor" with "columnsfirst" and "rowsfirst", respectively.
7907 * docs/gnuplot.doc: Correct the description of row and column layout
7908 'set term multiplot layout <rows>,<cols> {rowsfirst|columnsfirst}'
7910 2005-01-08 Harald Harders <h.harders@tu-bs.de>
7912 * src/pm3d.c src/term.c src/term_api.h term/epslatex.trm term/post.trm
7913 term/pslatex.trm: SF patch #1098252 "Use variable gppsfile for
7914 postscript output". This patch uses the variable gppsfile (formerly
7915 postscript_gpoutfile) instead of gpoutfile for all PostScript output.
7916 This is very useful for terminals that produce two files where one of
7917 them is PostScript (for example pslatex and epslatex).
7919 * src/color.c src/pm3d.c src/term.c src/term_api.h term/epslatex.trm
7920 term/post.trm term/pslatex.trm: SF patch #1098249 "Rename
7921 postscript_gpoutfile to gppsfile". This patch renames the handler
7922 'FILE *postscript_gpoutfile' to 'gppsfile' since the old variable name
7923 is too long for more often use.
7925 2005-01-05 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
7927 * src/util.h (try_to_get_string): Add missing 'void' to prototype
7930 * term/x11.trm: #include <sys/select.h>, if it exists.
7932 * src/stdfn.h: #include <sys/param.h> before checking if PATH_MAX
7933 is defined (definition may be in there...), rather than inside the
7934 fallback definition only.
7936 * term/svg.trm (SVG_init): Updated DOCTYPE name and reference to
7937 current standard: SVG 1.1. Added an XMLNS namespace declaration to
7938 satisfy requirements for XML documents.
7940 2005-01-05 Bastian Maerkisch <bmaerkisch@web.de>
7942 * src/os2/gclient.c: Some more cleanup: Removed some unused variables
7943 and unused code which eliminates a lot of compiler warnings.
7945 2005-01-04 Ethan Merritt <merritt@u.washington.edu>
7947 * src/term.c src/term_api.h: Instead of exporting ignore_enhanced_text
7948 from term.c as a global TBOOLEAN, provide a wrapper routine
7949 ignore_enhanced(TBOOLEAN flag);
7951 * src/graphics.c (do_plot) src/graph3d.c (do_3dplot): Call new routine
7952 ignore_enhanced() rather than directly setting a variable inside term.c.
7954 * src/gadgets.h: Add TBOOLEAN noenhanced flag to label_struct.
7956 * docs/gnuplot.doc src/set.c (set_xyzlabel) src/save.c (save_set_all)
7957 src/show.c (show_xyzlabel): New suboption `set ... {{no}enhanced}` for
7958 plot title and axis labels, analogous to the noenhanced option for the
7959 plot key entries. This allows, for example, using a filename with
7960 underscores as part of the plot title.
7962 * src/graphics.c (do_plot) src/graph3d (do_3dplot): Disable enhanced
7963 text processing while writing out plot title or axis label text if the
7964 noenhanced flag is set in the corresponding label_struct.
7966 * docs/gnuplot.doc: Correct the documentation to say
7967 'set multiplot layout <rows>,<cols>' (rows/cols were reversed in the
7968 previous version, and mis-described in the example).
7970 2005-01-04 Bastian Maerkisch <bmaerkisch@web.de>
7972 * src/os2/gclient.c: Contains my attempt to implement pattern filling
7973 for the pm terminal. I gave this a bit of testing, but I have to admit
7974 that the result looks ugly together with the widelines option. But
7975 here you go anyway as 'widelines' has to be improved later anyway. It
7976 should work fine without 'widelines'...
7978 * src/os2/gnupmdrv.c: Newer versions of gcc on OS/2 no longer have
7979 fcloseall(), but _fcloseall().
7981 * src/os2/gclient.c src/os2/dialogs.c src/os2/print.c: Clean up by
7982 removing some unused variables and code (some put into #if 0/#endif);
7983 some minor changes to layout - this basically removes anoying warning
7984 messages during compilation.
7986 2004-12-31 Ethan Merritt <merritt@u.washington.edu>
7988 * term/estimate.trm src/term.h: New pseudo-terminal driver whose sole
7989 function is to parse a string in enhanced text mode and return the
7990 number of character-widths in the resulting output text.
7992 * configure.in NEWS src/term_api.h src/term.c (estimate_strlen):
7993 New routine estimate_strlen(char *text). Its default behaviour is to
7994 return strlen(text). But if the currently active terminal is in
7995 enhanced text mode, and the current plotting context does not disable
7996 enhanced text, then instead it calls the estimate.trm pseudo-terminal
7997 term->put_text(text) in order to determine the approximate width of
7998 the eventual output string. This feature may be disabled using
7999 ./configure --disable-strlen_estimation
8001 * src/graph3d.c src/graphics.c: Where strlen(text) is used to reserve
8002 space on the plot (e.g. leaving room for tic labels or key box entries)
8003 call the new routine estimate_strlen(text) instead. This allows more
8004 accurate plot layout in enhanced text mode. The improvement is
8005 particularly noticible if the y-axis tic format uses enhanced text mode.
8007 * term/x11.trm (X11_options ENHX11_put_text): Try harder to determine
8008 what the default fontsize is so that string lengths can be estimated.
8010 2004-12-30 Ethan Merritt <merritt@u.washington.edu>
8012 * src/term_api.h term/README: Add a new terminal flag bit
8013 TERM_ENHANCED_TEXT that is set whenever the terminal is currently
8014 operating in enhanced text mode. The will allow improved estimation of
8015 text string length by the core code.
8017 * aquaterm.term dumb.trm gd.trm pdf.trm pm.trm post.trm svg.trm x11.trm:
8018 Set or clear TERM_ENHANCED_TEXT flag in term->options() code
8019 that parses the "{no}enhanced" terminal option.
8021 2004-12-29 Ethan Merritt <merritt@u.washington.edu>
8023 * src/mouse.c (MKSTR): Do not allow embedded newlines in the format
8024 used for tracking mouse motion via an extra status line at the bottom
8025 of the plot window. Extra newlines freeze gnuplot_x11 badly.
8027 2004-12-23 Ethan Merritt <merritt@u.washington.edu>
8029 * term/ggi.trm (GGI_fillbox GGI_set_color): Implement color selection
8030 by RGB values. Implement filled boxes. The GGI project seems moribund,
8031 so support of other new gnuplot features like polygons is unlikely.
8033 2004-12-22 Ethan Merritt <merritt@u.washington.edu>
8035 * src/mouse.c: Remove unused routine event_print().
8037 * src/mousecmn.h: Remove unused event types GE_stderr, GE_stdout,
8038 GE_cmd, and unused field text[100] in struct gp_event_t.
8040 2004-12-21 Ethan Merritt <merritt@u.washington.edu>
8042 * term/ggi.trm (GGI_replot) src/mousecmn.h src/mouse.c (do_event):
8043 Remove the one and only instance of GE_cmd as an event type, used
8044 by ggi.trm to trigger a replot. Create new type GE_replot instead.
8046 * term/ggi.trm (GGI_set_color): Convert to newer API for set_color.
8048 2004-12-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
8050 * term/emf.trm (EMF_filled_polygon): Renamed macro META_POLYGON to
8051 EMF_POLYGON, to avoid conflict with Win32 headers.
8053 2004-12-21 Petr Mikulik <mikulik@physics.muni.cz>
8055 * NEWS docs/gnuplot.doc src/pm3d.h src/pm3d.c src/save.c src/set.c
8056 src/show.c: New suboptions 'set pm3d corners2color min|max'.
8058 2004-12-20 Ethan Merritt <merritt@u.washington.edu>
8060 * term/fig.trm (FIG_put_text) term/gd.trm (PNG_put_text, ENHGD_FLUSH):
8061 Modify vertical centering text to match most other terminal types.
8062 This causes text rotation to occur about the vertical midpoint, as in
8063 the post, x11, pdf, and other terminals. (Bug #1086549)
8065 2004-12-20 Bastian Maerkisch <bmaerkisch@web.de>
8067 * term/pm.trm (PM_set_color): Reflect recent changes of parameters in
8070 * src/os2/gnupmdrv.h src/os2/gclient.c: gnupmdrv.c and gclient.c both
8071 used to define variable bWidelLines, but it should be the same one.
8072 This patch adds an 'external' declaration in gnupmdrv.h, and removes
8073 the definition from gclient.c.
8075 * src/os2/gclient.c: Within GnuplotPM "Options->Gnuplot docs...", it
8076 did not open gnuplot.inf when using NewView, a widely used view.exe
8077 replacement. Replaced the fixed sized buffer solution with code using
8080 * src/os2/gclient.c: This fixes text rotation for the pm terminal. The
8081 variable bHorz, which used to indicate horizontal text, has now been
8082 removed completely. Now pm terminal behaves similar to the postscript
8085 2004-12-15 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
8087 * src/parse.c (push_vars): Conditionalize definition on GP_ISVAR.
8088 (parse_primary_expression): Conditionalize use of push_vars and
8089 action PUSHV on GP_ISVAR.
8091 2004-12-14 Ethan Merritt <merritt@u.washington.edu>
8093 * demo/Makefile.am.in: Add rainbow.html and pointsize.html to the
8094 target list for "make html".
8096 2004-12-10 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
8098 * src/command.c (update_command): Fixed handling of optional
8099 second filename argument broken during introduction of
8100 try_to_get_string().
8102 2004-12-08 Shigeharu Takeno <shige@iee.niit.ac.jp>
8104 * term/tgif.trm: Update option parsing to be order-independent.
8105 Add monochrome and linewidth options.
8107 2004-12-07 Ethan Merritt <merritt@u.washington.edu>
8109 * term/emf.trm: Implement term->set_color(), term->filled_polygon,
8110 and term->fillbox() for the emf terminal. This does not provide PM3D
8111 palette support, but it does allow coloring by explicit RGB and plot
8112 styles that use filled boxes.
8114 2004-12-07 Petr Mikulik <mikulik@physics.muni.cz>
8116 * demo/pm3d.dem: Turn on colorbox in the demo of corners2color, and
8117 position it at the bottom of the page.
8119 2004-12-05 Ethan Merritt <merritt@u.washington.edu>
8121 Run valgrind to find memory leaks.
8123 * term/x11.trm (X11_make_palette): Free palette gradient after sending
8124 it to gnuplot_x11. Do other drivers have similar leaks?
8126 * src/set.c (set_cntrparam): Free old dynamic contour level array before
8129 * src/set.c (set_xyzlabel): Free dynamic label string after copying it
8130 to a static label structure.
8132 * src/parse.c (temp_at): Add a garbage-collection step to the
8133 deallocation of temporary storage for expression evaluation. I wish I
8134 understood this well enough to guarantee the correctness of scavenging,
8135 but empirical tests indicate that no double-free errors are triggered.
8137 2004-12-04 Ethan Merritt <merritt@u.washington.edu>
8139 Run valgrind to find codepaths that trip over uninitialized variables.
8141 * src/parse.c (const_express) src/set.c (set_xyzlabel set_label):
8142 src/eval.c src/eval.h: Move set/clear of flag STRING_RESULT_ONLY up
8143 one level in the call chain.
8145 * src/temp_api.h src/color.h src/graphics.c (init_histogram)
8146 src/plot2d.c (cp_alloc) src/plot3d.c (sp_alloc):
8147 More complete initialization of dynamic and gp_alloc()ed structures.
8149 2004-12-03 Ethan Merritt <merritt@u.washington.edu>
8151 * src/graphics.c (xtick2d_callback ytick2d_callback): Fix bug
8152 reported by Mike Kay: if the grid was active and the key box was
8153 entirely above or to the left of the graph itself, then an extraneous
8154 grid line was drawn connecting the key box to the graph.
8156 * src/set.c (set_palette): Fix bug #1077699 - parser was skipping
8157 whatever token came after "gamma <val>".
8159 2004-12-03 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
8161 * term/fig.trm (FIG_set_color): Fix a C99-ism. Thanks to Shigeharu
8162 Takeno for spotting this.
8164 2004-12-02 Ethan Merritt <merritt@u.washington.edu>
8166 * term/gd.trm: Keep track of current rgb values in parallel to the
8167 current linetype, since we can no longer count on regenerating the
8168 former from the latter.
8170 * term/x11.trm: Add missing X resource to the table in the docs.
8172 * configure.in: Remove obsolete messages relating to old png driver.
8174 2004-12-01 Ethan Merritt <merritt@u.washington.edu>
8176 Add colorspec to linetype, and hence to all 2D and 3D plot elements.
8177 These changes all depend on configuration with --enable-pm3d
8178 Add support and demo example of using explicit RGB colors or gnuplot's
8179 internal pre-defined color names:
8180 set style line 1 lt rgbcolor "violet" lw 2
8181 set style line 2 lt rgbcolor "#FFA080" lw 2 # salmon pink
8184 Add new field "struct t_colorspec pm3d_color" to lp_style_type, so that
8185 any plot element with an associated line type can use palette-based or
8188 * src/term.c (term_apply_lp_properties):
8189 Check lp_style_type.use_palette flag, and if set apply the colorspec
8190 rather than a simple linetype color.
8192 * src/misc.c (lp_parse parse_colorspec):
8193 Call parse_colorspec() as part of normal line type parsing. This allows
8194 "lt {rgbcolor 'name'} | {palette {cb <val> | frac <val> | z}}" anywhere
8195 that "lt <val>" is currently valid.
8197 * src/graphics.c (do_plot plot_boxes plot_c_bars do_key_sample):
8198 Everywhere that we would normally call t->linetype(), check use_palette
8199 and instead call apply_pm3dcolor()
8200 Everywhere that we would normally call t->fillbox(), check use_palette
8201 and instead call t->filled_polygon() via new routine fill_corners()
8203 * src/plot2d.c (eval_plots): Do not allow "lt palette z" in 2D plots
8205 * src/save.c src/show.c:
8206 save/show colorspec options associated with line styles and text colors
8209 Allow text color to use full colorspec options.
8211 * src/tables.c src/tables.h: New function reverse_table_lookup() that
8212 returns the keyword associated with a table value; this is used to look
8213 up the colorname associated with an RGB value.
8215 * NEWS docs/gnuplot.doc: Document new functionality and syntax.
8217 * demo/colorwheel.dem:
8218 Set palette mode to standard HSV color wheel and define common colors as
8219 macros. Allows terminal-independent commands such as
8220 plot sin(x) with lines @orange
8223 Demonstrate two approaches to defining terminal-independent colors for
8224 plot elements. (1) Load 'colorwheel.dem' to create a palette from which
8225 colors can be selected. (2) Use the new colorspec type RGB to request
8226 specific named colors, as in
8227 set style line 1 lt rgbcolor "sea-green"
8228 This only works well on terminals that support full RGB color modes.
8229 Some palette-based terminals will approximate the requested color using
8230 whatever palette color is closest, but the results may not be pleasing.
8232 2004-12-01 Ethan Merritt <merritt@u.washington.edu>
8234 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots): Add
8235 END_OF_COMMAND check before trying to parse possible backwards
8236 compatibility options. Fixes incorrect error message if text
8237 option parsing consumes the rest of the command line.
8239 2004-11-30 Petr Mikulik <mikulik@physics.muni.cz>
8241 * term/post.trm docs/Changes.doc: Typos.
8243 2004-11-29 Petr Mikulik <mikulik@physics.muni.cz>
8245 * term/pm.trm src/os2/gclient.c: Changes for the new colorspec type
8246 TC_RGB. Currently, they are dummy in gclient.c -- to be implemented.
8248 2004-11-27 Ethan Merritt <merritt@u.washington.edu>
8250 * docs/gnuplot.doc docs/gnuplot.texi: Re-format a large section of text
8251 dealing with binary files. The previous layout caused PDF output to
8252 treat the whole section as quoted monospace text, as for a code example.
8254 2004-11-27 Ethan Merritt <merritt@u.washington.edu>
8256 * src/color.h: Add new colorspec type TC_RGB, allowing colors to
8257 be specified as an RGB triple stored as (RR<<16)+(GG<<8)+BB with
8258 red, green, and blue components running from 0 - 255.
8260 * src/gadgets.c (apply_pm3dcolor) src/gadgets.h: Pass RGB color
8261 specifications to terminals via the new API for term->set_color().
8263 * src/gplt_x11.c src/gplt_x11.h term/*.trm (set_color):
8264 Implement set color to specified RGB triple in these terminals
8265 aquaterm gd metapost pdf post svg x11
8266 Somebody please have a look at doing the same for
8269 2004-11-26 Ethan Merritt <merritt@u.washington.edu>
8271 * src/term_api.h term/README: Change from term->set_color(double gray)
8272 to term->set_color(struct t_colorspec *colorspec). This sets the stage
8273 for allowing color specification mechanisms other than a PM3D palette.
8274 The immediate intent is to allow direct requests for RGB color values.
8276 * term/*.trm: Convert all terminal types providing set_color() to the
8277 new API. No change in terminal behavior or capabilities.
8279 aquaterm cgm fig gd metapost pdf post pslatex svg
8280 tgif vgagl win x11 pstricks
8282 * src/color.c (set_color): This is the only routine that calls
8283 term->set_color. Convert it to pass a colorspec pointer rather than a
8286 2004-11-25 Ethan Merritt <merritt@u.washington.edu>
8288 * src/util3d.h: map3d_xy_double is needed independent of WITH_IMAGE.
8290 2004-11-24 Ethan Merritt <merritt@u.washington.edu>
8292 src/gplt_x11.c: Set background color for pattern-fill explicitly each
8295 term/svg.trm (SVG_GroupOpen SVG_DefineFillPattern): Allow palette colors
8296 to be used in pattern fill.
8298 2004-11-23 Ethan Merritt <merritt@u.washington.edu>
8300 src/gplt_x11.c: Initialize mouse_format to null string. Fixes bug that
8301 in some circumstances the mouse position is printed as random garbage.
8303 2004-11-21 Ethan Merritt <merritt@u.washington.edu>
8305 Rearrange code so that pm3d support routines are available to both 2D
8306 and 3D plots. The addition of pm3d code to 2D plots began in portions
8307 of the WITH_IMAGE patch; remove the dependence on WITH_IMAGE to prepare
8308 for more general use of pm3d colorspecs in 2D plots.
8309 Introduce general checking for pm3d colorspecs in 2D plots. This fixes
8310 a bug that the colorbox could only be drawn for "with image" plots if
8311 the *first* plot used pm3d; subsequent plots were not checked.
8312 Also, pm3d colorspecs were already usable for text coloring in 2D, but
8313 no colorbox was drawn if they were used. Now it is.
8315 * src/color.h src/gadgets.h : Move definition of t_colorspec to color.h
8317 * src/color.h src/color.c src/graph3d.c src/graphics.c plot2d.c:
8318 Remove #ifdef WITH_IMAGE from several code segments that are useful for
8319 plot styles other than image.
8321 * src/misc.c src/set.c src/misc.h: Move parse_colorspec from set.c
8322 to misc.c and export it for use when parsing "with" options in both
8325 * src/plot3d.c src/pm3d.c src/pm3d.h src/graph3d.c:
8326 Move set_plot_with_palette and is_plot_with_palette from plot3d.c into
8327 pm3d.c so they can be shared by 2D and 3D code.
8329 * src/graphics.c: Check for is_plot_with_palette() and modify layout of
8330 2D plots to include colorbox if it returns TRUE.
8332 * src/color.c src/gadgets.c src/gadgets.h src/graph3d.c src/graphics.c:
8333 Rename apply_textcolor() to be apply_pm3dcolor(), since it is usable for
8334 any plot element requiring a palette-based color.
8336 2004-11-20 Ethan Merritt <merritt@u.washington.edu>
8338 * src/datafile.c (add_key_entry): Make sure all fields of newly
8339 allocated structure are initialized.
8341 * src/graph3d.c (do_3dplot) src/plot3d.h: Call utility function
8342 is_plot_with_palette rather than making plot_has_palette a global int.
8344 * src/util3d.h: map3d_xy_double is needed independent of WITH_IMAGE.
8346 * demo/pm3d.dem: Turn off colorbox in the demo of corners2color.
8348 2004-11-13 Ethan Merritt <merritt@u.washington.edu>
8350 * src/specfun.c (f_erf f_erfc f_normal): Replace in-line rough
8351 approximation for erf() and erfc() with calls to the internal
8352 routines that compute these values more accurately. This is only
8353 relevant to platforms that do not already provide math library
8354 routines erf() and erfc(). Empirical tests show that this change
8355 decreases the error relative to the double precision library
8356 erf routine from O(10^-8) to O(10^-16).
8357 Thanks to Dietmar Warning <warning@danalyse.de>
8359 2004-11-12 Ethan Merritt <merritt@u.washington.edu>
8361 * term/svg.trm (ENHsvg_writec): Escape character & to be & in
8362 output stream. '<' and '&' are the only escaped characters so far,
8363 and only in enhanced text mode.
8365 2004-11-12 Dietmar Warning <warning@danalyse.de>
8367 * src/specfun.c (inverse_error_func): Replace obsolete attribution of
8368 algorithm used for this function.
8370 * src/util3d.c (map_xy_double): This function is needed independent of
8371 the image code, so remove #ifdef WITH_IMAGE.
8373 2004-11-11 Ethan Merritt <merritt@u.washington.edu>
8375 * demo/datastrings.dem: Add example of using a column both as a
8376 numerical value and a string (use y value as a label).
8378 * src/graphics.h: New TBOOLEAM title_is_suppressed in plot structure
8379 src/graphics.c (find_maxl_keys do_plot)
8380 src/datafile.c (df_set_key_title) plot2d.c (cp_alloc eval_plots):
8381 Keep an explicit flag indicating whether or not the key should contain
8382 an entry for this plot.
8384 2004-11-11 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
8386 * docs/doc2texi.el (d2t-get-terminals): Fix search pattern for
8387 point where to insert terminal drivers after change of indentation
8388 level in gnuplot.doc.
8390 * docs/Makefile.in (TERM_H): New variable, points to term.h file
8391 in the src directory.
8392 (term.h): Rule generating this file disabled.
8393 (gnuplot.html, gnuplot.info): Removed superfluous dependencies on
8395 (gnuplot.texi): Run Emacs inside source directory --- building
8396 gnuplot.texi in an out-of-source build tree is futile, and never
8398 (doc2gih.o, doc2hlp.o, doc2ipf.o, doc2rnh.o, doc2rtf.o): Build
8399 online documentation tailored to actual program by including the
8400 real term.h, instead of a mangled copy.
8401 (BUILT_SOURCES): Removed term.h from the list.
8403 * docs/gnuplot.texi: Rebuilt.
8405 * docs/gnuplot.doc: Cleared some whitespace-only lines.
8407 2004-11-10 Ethan Merritt <merritt@u.washington.edu>
8410 * src/eval.c (gp_exp) src/specfun.c (f_gamma) src/standard.c (f_tanh):
8411 Rename constant MINEXP to be E_MINEXP, since this is more in line with
8412 the terminology used in standard math libraries. Only fall back to the
8413 current assumption that E_MINEXP == -88 if the build environment does
8414 not provide a definition for DBL_MIN_10_EXP, probably in <float.h>.
8415 On most machines this means that gnuplot's gamma() function should now
8416 have the same allowed input domain as exp(lgamma()).
8418 2004-11-10 Petr Mikulik <mikulik@physics.muni.cz>
8420 * src/save.c: Fix y-axes reversal when saving during 'set view map'.
8422 2004-11-08 Ethan Merritt <merritt@u.washington.edu>
8424 * src/term.c (do_arrow test_term): Do not attempt filled arrowheads if
8425 the current terminal does not provide term->filled_polygon(). Exercise
8426 filled arrowhead code in the 'test' command.
8428 * src/graphics.c (plot_image_or_update_axes): Do not attempt to draw
8429 rotated quadrangles if the current terminal does not provide
8430 term->filled_polygon().
8432 * docs/gnuplot.doc: Not all terminals support double-headed arrows.
8434 2004-11-08 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
8436 * src/hidden3d.c (build_networks): Fix 'with impulses' drawing
8437 style --- was off by one.
8439 2004-11-07 Ethan Merritt <merritt@u.washington.edu>
8441 * src/term.c (enhanced_recursion): Always allow backslash to escape the
8442 5 special formatting characters @^_~& in postscript enhanced text mode.
8443 This breaks certain character sequences in Shift-JIS, but the
8444 alternative makes these characters unavailable for all other encodings.
8446 * src/graphics.c (plot_vectors): Fix bug which drew a head on the tail
8447 of arrows whose original heads were clipped. Bug #1062158.
8449 2004-11-07 Petr Mikulik <mikulik@physics.muni.cz>
8451 * docs/gnuplot.doc: Typos.
8453 * term/tgif.trm: Replace "set nomultiplot" by "unset multiplot" in the
8456 2004-11-06 Ethan Merritt <merritt@u.washington.edu>
8458 String variables - command line macros
8459 --------------------------------------
8460 Command line macros are indicated by the character @ preceding a
8461 string variable. When the command line is read in, these macros are
8462 expanded by replacing the string @<varname> with the contents of the
8463 string variable <varname>. Macros can be nest up to 4 levels deep.
8464 Macros are not expanded inside single quotes or double quotes, but
8465 they are expanded inside backquotes.
8467 * configure.in: --enable-macros selects #define GP_MACROS
8469 * demo/macros.dem docs/gnuplot.doc: Examples and documentation.
8471 * src/command.c (do_line): Call new routine string_expand() that steps
8472 through input_line, expanded macros as it goes.
8474 * src/save.c (save_variables__sub): Save STRING variables in single
8475 quotes rather than in double quotes. That way when the saved values
8476 are loaded, no backquote substitution is triggered.
8478 * src/save.c src/set.c src/show.c src/unset.c src/tables.h src/tables.c
8479 src/command.c src/command.h: Global TBOOLEAN expand_macros to turn
8480 expansion on or off via new commands '{un}set macros'.
8482 2004-11-02 Ethan Merritt <merritt@u.washington.edu>
8484 * src/set.c: Use 0 rather than NULL in initializing a union, to make
8487 * src/plot3d.c: #include "plot2d.h" so that store_label is imported.
8489 * src/internal.c (sprintf_specifier): Add a useless return statement
8492 2004-11-01 Daniel Sebald <daniel.sebald@ieee.org>
8494 * src/datafile.c (df_readbinary): Do not try to access Z coordinate
8497 2004-10-31 Ethan Merritt <merritt@u.washington.edu>
8499 * src/datafile.c (df_readbinary): Fix incorrect indexing of 2D
8502 * src/mousecmn.h: Remove trailing comma from enum definition.
8504 * src/color.c (cbtick_callback) src/graph3d.c (do_3dplot xtick_callback
8505 ytick_callback ztick_callback map3d_position plot3d_vectors)
8506 src/mouse.c (nearest_label_tag):
8507 DEC cc is much pickier about mixing (unsigned int) and (int) across
8508 function calls or call-backs. Clean up the parameter usage to allow
8509 compilation under DU 4.0
8511 * src/internal.c (f_concatenate f_sprintf): Provide fallback for
8512 configurations that don't support snprintf().
8514 2004-10-29 Ethan Merritt <merritt@u.washington.edu>
8516 * docs/gnuplot.doc: Fix indentation level of terminal types when
8517 converted to pdf. Add mention of string variables in the documentation
8520 * src/gplt_x11.c (pr_exportselection) term/x11.trm:
8521 Add a test for X resource gnuplot*exportselection and disable exporting
8522 the plot windows to the X clipboard if it is set to "off" or "false".
8524 * NEWS: Catch up with recent work.
8526 2004-10-29 Petr Mikulik <mikulik@physics.muni.cz>
8528 * src/term.c docs/gnuplot.doc: Reset values of 'set size' and
8529 'set origin' after 'unset multiplot' to the values as they were at
8530 'set multiplot layout'.
8532 2004-10-28 Ethan Merritt <merritt@u.washington.edu>
8534 * src/datafile.c (df_open): initialize_user_spec() is needed whether or
8535 not the input mode is binary. Fixes bug reported under Windows.
8537 2004-10-27 Ethan Merritt <merritt@u.washington.edu>
8539 String variables - extra features
8540 ---------------------------------
8541 Autoconversion of strings to numerical values if encountered during
8542 evaluation of a numerical expression. ("3" + "4.5" == 7.5) is true.
8543 Autoconverion of integers to strings if encountered as an operand for
8544 string concatenation. ("file" . 4 eq "file4") is true.
8546 * configure.in: GP_STRING_VARS is #defined as 2 if these extra features
8547 are desired. Defining it as 1 leaves the basic feature set enabled but
8548 disables the extra stuff.
8550 * docs/gnuplot.doc src/eval.c src/eval.h src/internal.c src/standard.c:
8551 New routine pop_or_convert_from_string(), aliased to pop() during
8552 numerical evaluation. Treat INTGR operand to f_concatenate as a
8553 special case, promoting it to STRING.
8555 * src/parse.c (const_express):
8556 Suppress possible autoconversion to a number if the caller specifically
8557 expects a string value to be returned.
8559 2004-10-27 Petr Mikulik <mikulik@physics.muni.cz>
8561 * src/term.c docs/gnuplot.doc: New 'set multiplot layout' options
8562 'downwards' and 'upwards'.
8564 2004-10-26 Ethan Merritt <merritt@u.washington.edu>
8566 * docs/gnuplot.doc: Add separate section with indexed entry for
8567 discussion of quote marks.
8569 2004-10-25 Ethan Merritt <merritt@u.washington.edu>
8571 String variables - basic functionality
8572 --------------------------------------
8573 Allow gnuplot variables to contain strings, and allow expressions
8574 to operate on strings. Provide two pre-defined string-valued functions;
8575 sprintf() is a wrapper for the the C language formatting routine of the
8576 same name, gprintf() is a wrapper for the existing gnuplot-defined
8577 format specifiers. All changes are bracketed by #ifdef GP_STRING_VARS.
8578 Most places where gnuplot previously required a string constant will
8579 now also accept a string variable or a string-valued expression.
8582 * src/gp_types.h: STRING variable type
8584 * src/internal.c src/internal.h src/eval.c src/eval.h src/parse.c
8585 string operators (A . B) (A eq B) (A ne B)
8586 string functions sprintf() gprintf()
8588 * src/util.c (try_to_get_string) src/util.h: Modify the routine
8589 try_to_get_string to accept string variables and functions. This one
8590 place handles the syntax change for most gnuplot commands.
8591 The main exceptions are 'plot', 'splot', and 'set label', which are
8594 * src/scanner.c: accept . as a binary operator (string concatenation)
8596 * src/datafile.c: evaluate string-valued functions in a 'using' spec
8598 * src/mouse.c: set string variable MOUSE_CHAR when a key is pressed
8600 * src/plot2d.c: accept a string variable 'plot <foo>'
8602 * src/plot3d.c: accept a string variable 'splot <foo>'
8604 * src/set.c: accept a string variable in 'set label <foo>'
8606 * src/standard.c: int_error if a unary arithmetic operator is
8607 applied to a string.
8609 * demo/mousevariables.dem demo/keystroke.dem: Demo use of MOUSE_CHAR
8610 to treat keystrokes in the plot window as strings.
8612 * demo/stringvariables.dem: Demo use of constant strings or string-
8613 valued functions as plot symbols.
8615 2004-10-25 Harald Harders <h.harders@tu-bs.de>
8617 * docs/gnuplot.doc: Add labels for "set term push", "set term pop".
8618 SourceForge patch #1052788.
8620 2004-10-23 Ethan Merritt <merritt@u.washington.edu>
8622 * docs/gnuplot.doc: Reorganize the docs to give a separate section to
8623 the list of terminal types. This change is not visible to the internal
8624 'help' command, but improves the usability of the pdf and tex-based
8627 2004-10-22 Ethan Merritt <merritt@u.washington.edu>
8629 * docs/gnuplot.doc: A very preliminary update of the "What's New"
8630 section of the docs to track changes since the version 4.0 release.
8632 2004-10-21 Harald Harders <h.harders@tu-bs.de>
8634 This patch introduces the possibilty to move many kinds of texts by an
8635 offset in an arbitrary coordinate system. For example, tic marks, the
8636 title, and labels can be moved by an offset given in 'character',
8637 'screen', 'graph', 'first', or 'second' coordinate system.
8638 SourceForge patch #993422.
8642 * src/axis.c (get_position get_position_default):
8643 New routine that accepts a default coordinate type when parsing offsets.
8645 * src/axis.h: Add offset structure to axis tics.
8646 * src/gadgets.h: Add offset structure to text labels.
8648 * src/color.c (cbtick_callback draw_color_smooth_box)
8649 * src/gadgets.c (get_offsets)
8650 * src/save.c (save_set_all save_tics)
8651 * src/set.c (set_label set_timestamp set_tic_prop set_xyzlabel
8652 new_text_label parse_label_options parse_histogramstyle)
8653 * src/show.c (show_label show_histogram show_xyzlabel show_ticdef)
8654 * src/unset.c (unset_tics unset_axislabel_or_title)
8656 2004-10-20 Harald Harders <h.harders@tu-bs.de>
8658 Introduce a new coordinate system 'character' that uses character width
8659 and height as units. It is a 2d coordinate system similar to 'screen'.
8660 The origin is the same as for 'screen'. SourceForge patch #993411.
8661 The intended use is for setting label and text offsets in terms of
8662 character size, and generalizing this to all places where an offset is
8665 * NEWS docs/gnuplot.doc:
8666 * src/axis.h src/axis.c (get_position_type) src/gadgets.h:
8667 New coordinate system "character".
8669 * src/graph3d.c (get_arrow3d place_labels3d place_arrows3d):
8670 * src/graph3d.c (map3d_getposition map3d_position):
8671 Track 3D coordinates internally as (int) rather than (unsigned int) so
8672 that out-of-bounds on the negative side can be detected. Interpret
8675 * src/save.c (save_set_all) src/show.c (show_position show_arrowstyle):
8676 * src/graphics.c (map_position_double): Interpret character offsets.
8678 2004-10-20 Ethan Merritt <merritt@u.washington.edu>
8680 * src/gplt_x11.c (pr_font): Fix bug that whatever fallback font was used
8681 for an unrecognized font request, that fallback would become the default
8682 font for all future requests.
8684 2004-10-19 Juergen Wieferink <wieferink@freenet.de>
8686 * src/set.c (parse_label_options): If the label has an associated point,
8687 allow its type to be specified by "linestyle <n>".
8689 2004-10-19 Per Persson <persquare@mac.com>
8691 Adding enhanced text support to terminal aqua.
8693 * term/aquaterm.trm (ENHAQUA_put_text, ENHAQUA_open, ENHAQUA_flush,
8694 ENHAQUA_writec): Added.
8696 * docs/gnuplot.doc Add aqua to list of terminals with enhanced option.
8698 2004-10-18 Volker Dobler <v.dobler@web.de>
8699 Ethan Merritt <merritt@u.washington.edu>
8701 New plot style variant that reads individual point sizes from specified
8702 input column. Examples:
8704 plot 'foo' using 1:2:3 with points pt 5 pointsize variable
8705 splot 'foo' using 1:2:3:4 with linespoints pt 5 ps variable
8706 splot 'foo' using 1:2:3:4:5 with points pt 5 ps variable lt palette
8708 * NEWS docs/gnuplot.doc: Document new variant of line/point style in
8709 which the point size is variable, with the size of each point read from
8710 an extra column in the input file.
8712 * demo/all.dem demo/pointsize.dem: Demo for 2D and 3D plots with
8713 variable point size and pm3d colors.
8715 * src/gp_types.h: Define storage location for point size info in
8716 struct coordinate (overload xlow).
8718 * src/graph3d.c (plot3d_points plot3d_points_pm3d): Check for variable
8719 pointsize request and change point size before plotting.
8721 * src/graphics.c (do_plot plot_points): Check for variable pointsize
8722 request and change point size before plotting and in plot key.
8724 * src/misc.c (lp_parse): Parse "pointsize variable" in with spec.
8726 * src/plot2d.c (get_data eval_plots): Allow 3 columns of input for points,
8727 with the extra column holding point size.
8729 * src/plot3d.c (get_3ddata): Allow 4 columns of input for points with
8730 variable point size in 4th column, plus a possible 5th column of pm3d
8733 * src/save.c (save_set_all) src/show.c (show_linestyle): Print or save
8734 "pointstyle variable" characteristic of line style.
8736 2004-10-18 Ethan Merritt <merritt@u.washington.edu>
8738 * term/be.trm term/cgm.trm term/emf.trm term/epslatex.trm term/fig.trm
8739 term/gd.trm term/metapost.trm term/tgif.trm term/win.trm term/x11.trm:
8740 Add a check in TERM_pointsize() so that negative point size is reset to
8741 size 1.0. This has always been the case for the generic do_pointsize()
8742 routine in term.c, but not all of the individual terminals did likewise.
8744 2004-10-17 Ethan Merritt <merritt@u.washington.edu>
8746 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots):
8747 More stringent syntax test for bare numbers indicating line
8748 type in backwards-compatibility mode.
8750 2004-10-17 Juergen Wieferink <wieferink@freenet.de>
8752 * src/scanner.c (scanner): Terminate scan properly if an empty
8753 substitution occurs at the end of a line. bug #1045695
8755 2004-10-16 Ethan Merritt <merritt@u.washington.edu>
8757 * src/plot3d.c (get_3ddata): Reorganize the code so that fewer
8758 assumptions are made about what the plot must be based on the
8759 number of columns, and so that the various 3D mapping modes share
8760 the interpretations of columns other than the first three.
8762 src/plot3d.c (get_3ddata): Initialize variables to shut off stupid
8765 src/unset.c: #include hidden3d.c to pick up reset_hidden3doptions.
8767 2004-10-15 Ethan Merritt <merritt@u.washington.edu>
8769 * src/save.c (save_set_all): Do not try to save the current title and
8770 text properties of histograms. This is not part of the permanent style.
8771 Fixes strangeness with "test palette".
8773 2004-10-14 Ethan Merritt <merritt@u.washington.edu>
8775 * src/plot2d.c (get_data eval_plots): Defer adjustment of histogram
8776 ranges until after the input file has been checked for valid data.
8777 (fixes bug #1046894)
8779 * src/datafile.c (df_parse_string_field): Handle missing field in
8780 input file more gracefully. (bug #1046894)
8782 * src/graph3d.c (map3d_position_r): Remove unused variables.
8784 2004-10-13 Harald Harders <h.harders@tu-bs.de>
8786 * src/graph3d.c (map3d_position_r get_arrow3d):
8787 Change the interface of the function map3d_position_r() to be similar
8788 to map_position_r(). Now, map3d_position_r() does not need to get the
8789 startpoint. This will make it easier to use it for all kinds of
8790 relative coordinates as text offsets.
8792 * src/graphics.c (get_arrow): map_position_r already handles the
8793 relative position; no need to duplicate it in get_arrow.
8795 * docs/gnuplot.doc: Mention that relative coordinates in log scale
8796 imply a multiplicative rather than an additive offset.
8798 2004-10-12 Ethan Merritt <merritt@u.washington.edu>
8800 * src/graphics.c (place_labels): Add a TBOOLEAN flag to indicate whether
8801 labels should be clipped against the current axis limits. Labels
8802 generated by "set label <foo>" are never clipped; labels generated by
8803 'plot with labels' are clipped.
8805 * src/graphics.c (fill_between): Improve clipping to handle 1st/2nd axes
8806 and inverted axis range.
8808 2004-10-11 Petr Mikulik <mikulik@physics.muni.cz>
8810 * src/mouse.c (apply_zoom): Fix for reversed y-range in zoom by mouse
8813 * src/graphics.c (do_plot): Better warning for trying to use pm3d in a
8816 2004-10-08 Petr Tobiska <tobiska@ure.cas.cz>
8818 * term/metapost.trm (MP_arrow): Handle double-ended arrows also.
8820 2004-10-05 Ethan Merritt <merritt@u.washington.edu>
8822 * src/gplt_x11.c (pr_font): Release previous font every time a new one
8823 is requested. This feels wrong to me since we know the old font will be
8824 used again very soon, but otherwise there is a serious memory leak.
8826 * src/gplt_x11.c (PaletteMake): (Daniel Sebald <daniel.sebald@ieee.org>)
8827 Fix another tiny memory leak.
8829 * src/plot3d.c (get_3ddata): Add missing #ifdef EAM_DATASTRINGS.
8831 * configure.in: If --disable-datastrings is selected, then turn off
8832 histogram support also since it is crippled without the
8835 2004-10-05 Petr Mikulik <mikulik@physics.muni.cz>
8837 * config/config.cyg config/config.mgw config/config.os2: Added #defines
8838 EAM_DATASTRINGS and EAM_HISTOGRAMS.
8840 * src/makefile.all: Added breaders.$(O) to COREOBJS.
8842 2004-10-04 Ethan Merritt <merritt@u.washington.edu>
8844 * term/x11.trm (X11_graphics): Initialize font-tracking variable at the
8845 start of each plot (fixes problems seen with opening multiple plot
8846 windows with different default fonts).
8848 2004-10-04 Petr Mikulik <mikulik@physics.muni.cz>
8850 * src/gplt_x11.c (process_event): Added missing cmd_tried = 1.
8852 2004-10-03 Daniel Sebald <daniel.sebald@ieee.org>
8854 * src/gplt_x11.c (delete_plot): Fix small memory leak.
8856 2004-10-01 Ethan Merritt <merritt@u.washington.edu>
8858 * src/plot3d.c (get_3ddata): Allow explicit pm3d palette colors for line
8859 and point styles in non-Cartesian mapping modes. (bug #1005775)
8861 2004-09-30 Ethan Merritt <merritt@u.washington.edu>
8863 * term/gd.trm: Change #ifdef GD2_VERS to #if (GD2_VERS >= 2) everywhere.
8865 * term/emf.trm (EMF_set_font) term/tgif.trm (TGIF_set_font):
8866 Fix longstanding problems with the set_font routines;
8867 interpret font requests of the form ",<size>" as a request to rescale
8868 the current font to <size>.
8870 2004-09-29 Ethan Merritt <merritt@u.washington.edu>
8872 * demo/all.dem: Remove vector.dem again, since it turns out that it
8873 breaks for any terminal type whose default value of 'set output' is
8874 not the current display.
8876 * demo/world2.dem: Set font explicitly to "Helvetica,7", since some
8877 terminal drivers do not like the partial font spec ",7".
8879 * src/hidden3d.c (set_hidden3doptions) src/hidden3d.h
8880 src/unset.c (reset_command): New routine reset_hidden3doptions()
8881 called by "set hidden defaults" and also by "reset".
8883 * term/post.trm (PS_set_font ENHPS_set_font) term/pdf.trm (PDF_set_font)
8884 term/svg.trm (SVG_set_font): Do not allow the font to be set to "";
8885 interpret font requests of the form ",<size>" as a request to rescale
8886 the current font to <size>.
8888 2004-09-29 Petr Mikulik <mikulik@physics.muni.cz>
8890 * src/datafile.c (df_show_binary): In fprintf(), use "%f" not "%lf" for
8893 2004-09-27 Ethan Merritt <merritt@u.washington.edu>
8895 * demo/airfoil.dem demo/fillcrvs.dem demo/histograms.dem
8896 demo/histograms2.dem demo/spline.dem demo/world.dem:
8897 Replace all instances of outdated syntax, i.e. everything that causes
8898 errors or warnings if BACKWARDS_COMPATIBLE is not defined.
8900 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots): Wrap the code
8901 which interprets bare line+point types with #ifdef BACKWARDS_COMPATIBLE
8902 (e.g. plot 'foo' with linespoints 3 4).
8904 2004-09-27 Petr Mikulik <mikulik@physics.muni.cz>
8906 * src/os2/gclient.c: Fix typo in a #define from the previous massive
8909 * config/config.os2: Let #define STDC_HEADERS 1.
8911 2004-09-26 Ethan Merritt <merritt@u.washington.edu>
8913 * src/plot3d.c (eval_3dplots): Fix logic of default arrow style in the
8914 case of splot with vectors.
8916 2004-09-25 Ethan Merritt <merritt@u.washington.edu>
8918 * src/util3d.c src/util3d.h: Add a text_label pointer to the p_vertex
8919 structure in order to support labels in hidden3d mode.
8921 * hidden3d.c (build_networks draw_vertex): Add code to handle plot style
8922 "with labels" in hidden3d mode.
8924 * demo/world2.dem demo/srl.dat: New demo to show use of labels with pm3d
8925 colors and hidden3d mode.
8927 * demo/all.dem demo/Makefile.am.in: Add vector.dem and world2.dem.
8929 2004-09-24 Ethan Merritt <merritt@u.washington.edu>
8931 * src/graphics.c (get_offsets place_labels) src/graphics.h:
8932 Simplify place_labels by calling a new shared routine.
8933 Move the support routine get_offsets into gadgets.c as well.
8935 * src/graph3d.c (plot_labels3d): Simplify place_labels3d by calling
8936 a new shared routine.
8938 * src/gadgets.c (get_offsets write_label) src/gadgets.h:
8939 New routine write_label that is shared by both the 2D and 3D code.
8941 * demo/fit.dem demo/vector.dem demo/histograms2.dem:
8942 Revise demo instructions slightly to work with the webify script.
8944 * demo/webify.pl: Use "pause 0" in demo scripts to signal that the
8945 output file needs to be reset during web page generation.
8947 * demo/Makefile.am.in: Update list of demos to include in web page
8948 generation ("make html").
8950 2004-09-20 Ethan Merritt <merritt@u.washington.edu>
8952 * configure.in: --enable-with-image requires both pm3d and binary file
8953 support. Enforce this in the configure script by not allowing with-image
8954 to be enabled if the other two options have not also been enabled.
8956 2004-09-21 Petr Mikulik <mikulik@physics.muni.cz>
8958 * docs/gnuplot.doc: Fix documentation for multiplot.
8960 * src/term.c: Better error message for an invalid option of multiplot.
8962 2004-09-20 Ethan Merritt <merritt@u.washington.edu>
8964 * docs/gnuplot.doc: Fix some minor errors that interfered with
8967 2004-09-19 Ethan Merritt <merritt@u.washington.edu>
8969 * src/graph3d.c (do_3dplot plot3d_vectors) src/graph3d.h
8970 src/plot3d.c (get_3ddata eval_3dplots): Extend the plotting style
8971 "with vectors" to apply to 3D plots as well.
8972 splot 'data' using <x>:<y>:<z>:<delx>:<dely>:<delz> with vectors \
8974 Only cartesian coordinate mapping is currently supported.
8976 * docs/gnuplot.doc NEWS: Document extension to 3D.
8978 2004-09-17 Harald Harders <h.harders@tu-bs.de>
8980 * term/README term/debug.trm term/gd.trm: Fix typos and add
8981 information about enhanced text mode callback entries in TERM_TABLE.
8983 * term/post.trm: Move definition of /Rounded to the top of the
8984 prolog so that it is with the other user-editable definitions.
8986 2004-09-17 Petr Mikulik <mikulik@physics.muni.cz>
8988 * NEWS docs/gnuplot.doc src/misc.c: New automatic variable $# gets
8989 expanded to number of arguments after "call <file>". SF patch #943749.
8991 2004-09-16 Ethan Merritt <merritt@u.washington.edu>
8993 * src/set.c (set_timestamp set_xyzlabel) src/save.c (save_set_all)
8994 demo/contours.dem demo/surface1.dem docs/gnuplot.doc:
8995 Add keyword "offset" to commands of the form
8996 old: set xlabel "foo" -1,-1
8997 new: set xlabel "foo" offset -1,-1
8998 This is necessary to pave the way for string variables, as otherwise
8999 "set title var -1" is mis-parsed as containing the arithmetic expression
9000 (var-1). To maintain backward compatability, the keyword is optional.
9002 2004-09-16 Harald Harders <h.harders@tu-bs.de>
9004 * term/post.trm (delete_ps_fontfile): Remove debugging printout line.
9006 2004-09-15 Ethan Merritt <merritt@u.washington.edu>
9008 * src/plot3d.c (get_3ddata) src/graphics.c (boundary) term/x11.trm:
9009 Add #ifdefs so that ./configure --disable-pm3d will build successfully.
9011 * term/fig.trm term/epslatex.trm term/pslatex.trm term/metapost.trm
9012 term/tgif.trm term/pstricks.trm: Disentangle the ordering of #ifdefs
9013 in the TERM_TABLE entries (MOUSE is not a subset of PM3D).
9015 * term/emf.trm: Remove unused label to quiet compiler warnings.
9017 2004-09-15 Konstantin Korikov <lostclus@ua.fm>
9019 * NEWS docs/gnuplot.doc src/gplt_x11.c src/set.c src/term_api.h
9020 src/term.c term/post.trm: Add support for character encoding koi8-u
9021 (cyrillic koi8 for Ukrainian users).
9022 SourceForge patch #966815.
9024 2004-09-14 Ethan Merritt <merritt@u.washington.edu>
9026 * demo/borders.dem demo/Makefile.am.in: Rewrite the borders demo to
9027 terminate after 16 possible settings, to display the border setting in
9028 a label, and to execute from inside a single demo file rather than a
9029 combination of two. Thanks to Daniel Sebald for identifying that it
9032 * src/term.c (do_arrow): Interpret (head < 0) as "draw arrowhead only".
9033 This allows us to retrace the arrowhead in a different linestyle if
9036 * term/post.trm (PS_arrow): Add a wrapper for the do_arrow() routine
9037 so that if the current linestyle is dashed we can retrace the arrowhead
9038 with a solid line. Addresses bug report #963213.
9040 * term/pslatex.trm (PSLATEX_arrow): Piggyback on PS_arrow to apply
9041 the same fix for pslatex. Any other terminals with dashed lines will
9042 have to be fixed separately.
9044 2004-09-13 Daniel Sebald <daniel.sebald@ieee.org>
9046 * src/datafile.c: Rework the layout of the df_bin_default_columns
9047 array, so that the binary input code is not sensitive to the order of
9048 defining plot styles in gp_types.h.
9050 2004-09-13 Ethan Merritt <merritt@u.washington.edu>
9052 * src/gplt_x11.c: Trivial cleanup to remove compiler warnings.
9054 * term/post.trm: Keep track of whether or not the macro definitions
9055 required for enhanced text mode have been written to the output file
9056 yet. If enhanced text mode is enabled after the terminal has already
9057 been initialized, make sure that the macros are added to the next
9058 output page. This allows, for example,
9059 setenv GNUTERM post; gnuplot all.dem > all.ps
9060 Without this fix, the output pages following the enhanced text demo
9061 are corrupted. An alternative would be to write the enhanced text
9062 macros in the %%Prolog for every PostScript output file regardless of
9063 whether enhanced text mode has been selected.
9065 2004-09-11 Ethan Merritt <merritt@u.washington.edu>
9067 * src/command.c src/mouse.c src/parse.c src/parse.h: Rename utility
9068 function get_udv(char *name) to be add_udv_by_name(char *name), since
9069 this is what it really does.
9071 * src/fit.c (setvar): Simplify existing code by using add_udv_by_name.
9073 * src/set.c (set_termoptions): Update comment explaining this routine.
9075 * src/plot3d.c (eval_3dplots): Surface plots are no longer the only
9076 plot style that can have four 'using' specs; remove the error check
9077 that incorrectly prevents this.
9079 * src/plot3d.c (get_3ddata set_plot_with_palette)
9080 src/plot2d.h src/plot2d.c (store_label): Allow palette color options
9081 for text in "{s}plot with labels textcolor palette ...".
9083 * src/set.c (parse_colorspec): If "tc palette" is specified with no
9084 further suboptions, default to "tc palette z".
9086 * src/plot3d.c (get_3ddata): Allow palette color options in cylindrical
9087 and spherical coordinate modes also.
9089 2004-09-09 Harald Harders <h.harders@tu-bs.de>
9091 * term/post.trm: Update the comment on plot-time evaluation of
9092 PostScript language level support.
9094 2004-09-09 Shigeharu Takeno <shige@iee.niit.ac.jp>
9096 * docs/gnuplot.doc, term/cgm.trm, term/eepic.trm, term/emf.trm,
9097 term/epslatex.trm, term/post.trm: Fix misprints in gnuplot manual (#15).
9099 2004-09-07 Ethan Merritt <merritt@u.washington.edu>
9101 * src/gplt_x11.c (process_event) term/x11.trm: Provide a command line
9102 option (-ctrlq) and an X resource (gnuplor*ctrlq: true) that disable
9103 trapping the 'q' and '<space>' keystrokes in the plot window, instead
9104 trap <ctrl>q and <ctrl><space>. This option allows the 'q' and
9105 '<space>' keystrokes to be treated like all other keystrokes during
9106 "pause mouse key" and other mousing operations.
9109 2004-09-06 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9111 * configure.in (AC_PREREQ): Bumped to 2.58, to avoid problems with
9112 missing AC_HEADER_STDBOOL.
9114 2004-09-06 Daniel Sebald <daniel.sebald@ieee.org>
9116 * configure.in: The --enable-image option requires general binary data
9117 file code. Ensure --disable-binary-data-file is not in the option list
9118 if only --enable-image is activated.
9120 2004-09-06 Petr Mikulik <mikulik@physics.muni.cz>
9122 * config/config.cyg config/config.mgw config/config.os2: Added #defines
9125 2004-09-03 Daniel Sebald <daniel.sebald@ieee.org>
9127 * src/breaders.c src/datafile.c: Get rid of compiler warnings.
9129 2004-09-03 Petr Mikulik <mikulik@physics.muni.cz>
9131 * src/datafile.c: Changed default value of datafile endianess after
9132 reset: from variable df_bin_file_endianess_reset = DF_LITTLE_ENDIAN to
9133 #define DF_BIN_FILE_ENDIANESS_RESET THIS_COMPILER_ENDIAN.
9135 2004-09-03 Shigeharu Takeno <shige@iee.niit.ac.jp>
9137 * demo/image.dem: Added endian=little where necessary.
9139 2004-09-02 Ethan Merritt <merritt@u.washington.edu>
9141 * demo/all.dem: Include demos for candlesticks, multiplot, and
9142 enhanced text mode in the all.dem script used by "make check".
9144 2004-09-01 Ethan Merritt <merritt@u.washington.edu>
9146 * term/gd.trm (PNG_set_color PNG_image) term/pdf.trm (PDF_image)
9147 term/post.trm (PS_image): Change call from rgb255_from_gray() to
9148 rgb255maxcolors_from_gray(). Fixes color mapping with 'set palette
9151 * src/getcolor.c: Remove unused routine rgb255_from_gray.
9153 * term/gd.trm: Add WITH_IMAGE support for gif terminal also.
9155 2004-09-01 Lars Hecking <lhecking@nmrc.ucc.ie>
9157 * demo/Makefile.am.in: Add new binary demo files to Makefile.am
9160 src/Makefile.am: Add missing binary.h to bf_test_SOURCES.
9162 2004-09-01 Daniel Sebald <daniel.sebald@ieee.org>
9166 * configure.in: Added enable and define switches to activate new
9168 WITH_IMAGE (--enable-with-image) code for plotting images
9169 WITH_IMAGE_VERIFY_ALL_PIXEL_LOCATIONS (--enable-image-grid-verify)
9170 code for verifying every point in image grid is uniformly spaced
9171 BINARY_DATA_FILE (--enable-binary-data-file) code to allow reading
9172 general binary data files
9173 BINARY_X11_POLYGON (--enable-binary-x11-polygon) code for X11 that
9174 allows transferring polygon information as binary values rather
9175 than ASCII, to save space in plot buffers
9177 * demo/all.dem: Added inclusion of image.dem.
9179 * demo/asciimat.dat demo/blutux.rgb demo/demo.edf demo/scatter2.bin
9180 demo/sine.bin demo/using.bin: New datafiles required by image.dem.
9182 * demo/image.dem: New demo to illustrate and test various new image
9183 and binary and matrix data file features.
9185 * docs/gnuplot.doc: Added documentation for image features and general
9186 binary file syntax. Also, removed language indicating gnuplot matrix
9187 binary is restricted to `splot`, as it now can be used for images in
9190 * src/Makefile.am: Added gplt_x11.h to gnuplot_SOURCES list and
9191 gnuplot_x11_SOURCES list. Added bin_hook.c to gnuplot_SOURCES list and
9192 removed binary.c and binary.h from this list.
9194 * src/README: Added a discussion of technical details about how the
9195 formulas for properly orienting an image and passing that to the
9196 terminal driver are derived. They can be arcane if just looking at the
9197 code inside plot_image_or_update_axes(). Same goes for the details
9198 about sending binary data to gnuplot_x11 for images. It requires a
9199 simple heuristic encoding scheme to avoid a few particular characters
9200 from the data stream and can appear confusing at first sight.
9202 * src/bin_hook.c: A new, short file to include binary.c in the source
9203 tree if BINARY_DATA_FILE is not defined. Otherwise, binary.c is no
9206 * src/breaders.h: An example of how to read a header in a particular
9207 file format and fill in the general binary structure details. Not
9208 completely sure just yet how this should be integrated into gnuplot.
9210 * src/color.c (draw_color_smooth_box): Added an option for `plot` mode
9211 for use in images with a palette.
9213 * src/color.h: Adjusted function definition for change noted above.
9215 * src/command.c: Now save a new property is_cb_plot to determine if a
9216 color box can be part of the plot in question.
9218 * src/command.h: Added declaration of is_cb_plot variable.
9220 * src/datafile.c: Extensive additional code for interpreting general
9221 binary keyword syntax. Changed df_readline() to df_readascii() and
9222 added a new file df_readbinary() analogous to df_readascii(). A new
9223 df_readline() chooses which of these two to utilize. Code for reading
9224 binary and ASCII matrix format file was moved to df_readbinary(). This
9225 means other files in the source tree could be restructured so that the
9226 routine df_readline() is the only method to bring data into gnuplot.
9228 * src/datafile.h: Declarations for new functions as part of code noted
9229 above. Also, there are a few new enumerations and, most importantly,
9230 the definition for the structure containing information about general
9233 * src/fit.c (fit_command): Altered df_open() argument to include the
9234 plot mode MODE_QUERY.
9236 * src/getcolor.c: Reactivated rgb255_from_gray(), required for images.
9238 * src/gp_types.h: Added IMAGE and RGBIMAGE to PLOT_STYLE enumeration.
9240 * src/gplt_x11.c: Extensive additional code for handling images in
9241 binary data format, polygons in binary data format, and an endianess
9242 check to determine if bytes need be swapped. A simple, short encoding
9243 scheme is used for binary data to avoid a couple special characters in
9246 * src/gplt_x11.h: A new header file to go along with gplt_x11.h
9247 containing definitions for code characters sent across pipe. Also some
9248 definitions for translation characters in the binary encoding scheme.
9250 * src/graph3d.c (do_3dplot): Added a plot_mode of MODE_SPLOT to
9251 argument of draw_color_smooth_box(), as now that can also be done for
9252 `plot`. Also, added cases of IMAGE and RGBIMAGE to plot style switch.
9254 * src/graphics.c: Added plot_image_or_update_axes(), a new image
9255 plotting routine. The new routine is fairly long and arcane in spots.
9256 The README file contains details to clear up obscure parts. Added the
9257 cases IMAGE and RGBIMAGE to the switch statement for plot style. Also,
9258 there is code for making room for a color box on the plot, followed by
9259 a call to draw_color_smooth_box() where appropriate.
9261 * src/graphics.h: Added definitions PLOT_IMAGE(), SPLOT_IMAGE() and
9262 UPDATE_AXES_FOR_PLOT_IMAGE() to make plot_image_or_update_axes() seem
9265 * src/misc.c: Added 'image' and 'rgbimage' to list of plot styles in
9266 error message indicating valid styles.
9268 * src/mouse.c (builtin_toggle_log): For plots having a color box
9269 property, allow changing the color box to logarithmic scale.
9271 * src/plot2d.c: Many small alterations to case statements, etc. to
9272 integrate IMAGE and RGBIMAGE plot styles. Also, added MODE_PLOT to
9273 df_open() argument list for binary data files.
9275 * src/plot3d.c: Similar to plot2d.c, many little changes made to
9276 incorporate IMAGE and RGBIMAGE plot styles. Also, for general binary
9277 there is no longer need for df_3dmatrix(), so that call was removed.
9278 Added MODE_SPLOT to argument list of df_open().
9280 * src/save.c (save_data_func_style): Write `image` or `rgbimage` to
9281 file if appropriate plot style.
9283 * src/set.c (set_command/set_palette_file): Added call to routine
9284 setting defaults for binary data files if `binary` is specified as
9285 part of `set` command. / Added MODE_QUERY to list of arguments for
9288 * src/show.c (show_datafile): Now show information about binary data
9289 file settings and details about binary variable sizes in bytes for the
9290 compiler under which gnuplot was built.
9292 * src/tables.c (show_style_tbl): Added `image` and `rgbimage` to table.
9294 * src/term_api.h (TERMENTRY): Added image() prototype function to
9295 TERMENTRY structure as well as an enumeration for image type as an
9296 argument to image() routine.
9298 * src/unset.c (unset_command/reset_command): Added call to routine that
9299 clears the binary data file record information.
9301 * src/util3d.c: Added a routine map3d_xy_double() to retain more
9302 accurate coordinates necessary for checking uniformity of the image
9303 grid via hyperplane concepts. It is repetition of existing code,
9304 but there is a note and define switch for code-reuse.
9306 * src/util3d.h: Added declaration for map3d_xy_double().
9308 * term/README: Added note about how to properly use image() terminal
9311 * term/aquaterm.trm: Per Persson added an implementation of the image()
9312 terminal function, AQUA_image().
9314 * term/dumb.trm: Ethan Merritt added a space filler for the image()
9315 terminal function location of TERM_TABLE.
9317 * term/epslatex.term: Added PS_image() to structure for image() in
9318 TERM_TABLE. PS_image() is in post.trm.
9320 * term/gd.trm: Ethan Merritt added a routine PNG_image() for the
9321 TERM_TABLE entry of image(). Also, a supporting routine PNG_set_color
9324 * term/pdf.trm: Ethan Merritt added a routine PDF_image() and entry
9325 into the TERM_TABLE for image support for PDF files.
9327 * term/post.trm: Added a routine PS_image() and appropriate entry in
9328 the TERM_TABLE for image support in PostScript files. There is also a
9329 supporting routine PS_encode85() for encoding binary image data in
9330 ASCII85 data format.
9332 * term/pslatex.trm: Added PSLATEX_image() to structure for image() in
9333 TERM_TABLE. It uses a simple call to PS_image(), which is in post.trm.
9335 * term/svg.trm: Added space filler in TERM_TABLE for image() function.
9337 * term/x11.trm: Added X11_image() function and entry in TERM_TABLE.
9338 The new image routine contains code for a simple, heuristic encoding
9339 scheme to prevent a couple specific bytes from being in the image data
9340 stream. Similarly, X11_filled_polygon() and X11_set_color() were
9341 altered to use the same scheme to reduce the amount of characters
9342 inside the plot buffer.
9344 2004-08-27 Per Persson <persquare@mac.com>
9346 * src/term.c (init_terminal): Make aqua the default terminal on
9347 Mac OS X if AquaTerm is installed.
9349 2004-08-27 Ethan Merritt <merritt@u.washington.edu>
9351 * term/gd.trm (PNG_vector): More specific test for libgd support of
9352 antialiasing. Versions 2.0.0 -> 2.0.11 were not correctly handled by
9355 2004-08-25 Ethan Merritt <merritt@u.washington.edu>
9357 * src/plot.c (main): Call term->options() on entry if the default
9358 terminal type is png, jpeg, or tgif. Without this, setting GNUTERM
9359 to this driver type causes a segfault due to incomplete initialization
9360 of the driver data structures. I believe this call to term->options()
9361 would be OK for all other drivers as well, but to be on the safe side
9362 I added it only for the drivers I know will segfault without it.
9364 * term/gd.trm: New option to generate truecolor png images.
9365 set term png .. {{no}truecolor} ..
9367 * term/gd.trm (PNG_vector): Use anti-aliasing for vectors if possible.
9368 This does not affect palette-based PNG images, so far as I can tell,
9369 but does work for both JPEG and TrueColor PNG images.
9371 2004-08-25 Per Persson <persquare@mac.com>
9373 * term/aquaterm.trm (AQUA_options): make options order-independent;
9374 replace isstring+quote_str with try_to_get_string();
9375 allow "font" as a synomym for "fname".
9377 2004-08-23 Ethan Merritt <merritt@u.washington.edu>
9379 * term/xlib.trm (Xlib_text): Leave output file open so that it is
9380 possible to plot multiple frames without another 'set term xlib'.
9382 * svg.trm (SVG_options): allow "font" as a synonym for "fname";
9383 replace isstring+quote_str with try_to_get_string();
9384 new option "linewidth <n>".
9386 * pdf.trm (PDF_options): make options order-independent;
9387 replace isstring+quote_str with try_to_get_string();
9388 allow "font" as a synomym for "fname";
9389 new option "linewidth <n>".
9391 * post.trm (PS_options): allow "font" as a synonym for "fname"
9393 * fig.trm (FIG_options): allow "linewidth" as a synonym for "thickness".
9395 2004-08-23 Shigeharu Takeno <shige@iee.niit.ac.jp>
9397 * docs/gnuplot.doc: Fix misprints in gnuplot manual (#14).
9399 2004-08-20 Ethan Merritt <merritt@u.washington.edu>
9401 * src/set.c (set_termoptions): Only call term->options for
9402 terminals that actually support the option in question.
9404 * src/term.c (write_multiline) term/driver.h: Remove unused
9405 function set_font_null; instead mark lack of font support by
9406 initializing this TERM_TABLE entry to NULL. Fixes segfault
9407 if font is checked before terminal is initialized, and allows
9408 non-destructive test of font support.
9410 2004-08-20 Ethan Merritt <merritt@u.washington.edu>
9412 * src/set.c (set_termoptions): Quietly ignore the command if there
9413 is no current terminal.
9415 2004-08-19 Ethan Merritt <merritt@u.washington.edu>
9417 * src/set.c (set_termoptions): Fill in basic implementation of this
9418 function that allows changing one characteristic of the current
9419 terminal. So far the only allowed changes are the default font and
9420 {no}enhanced text mode.
9422 * demo/enhancedtext.dem: Use 'set termoption enhanced' (new command)
9423 to force enhanced text mode regardless of current terminal type.
9425 * docs/gnuplot.doc: Document 'set termoption <foo>'.
9427 * NEWS: Update NEWS file to cover post-4.0 development work.
9429 2004-08-18 Volker Dobler <v.dobler@web.de>
9431 * src/term.c (term_end_plot term_start_multiplot term_end_multiplot):
9432 Implement auto-layout of multiplots with specified number of rows
9435 * docs/gnuplot.doc demo/layout.dem: Document and illustrate use
9436 of 'set multiplot layout'.
9438 2004-08-18 Ethan Merritt <merritt@u.washington.edu>
9440 * term/svg.trm: More consistent handling of default background and font.
9442 2004-08-17 Ethan Merritt <merritt@u.washington.edu>
9444 * src/eval.c (real imag magnitude angle): Move error message handling
9445 into default case of switch statements (prevents compiler warnings).
9447 * src/plot2d.c (eval_plots) src/graphics.c (init_histogram):
9448 Replace instance of isstring + quote_str with try_to_get_string().
9449 Make histogram_title a dynamically allocated string rather than a fixed
9450 length char constant.
9452 2004-08-15 Ethan Merritt <merritt@u.washington.edu>
9454 * demo/histograms.dem: Revise bmargin settings to work with the revised
9455 bmargin handling in graphics.c (2004-07-25).
9457 * src/plot2d.c (eval_plots): Fixed bug in "newhistogram 'title' ..."
9458 that caused the title to be ignored if there were no other options
9461 2004-08-13 Shigeharu Takeno <shige@iee.niit.ac.jp>
9463 * src/term.c (enhanced_recursion): Pass unescaped backslash character
9464 through to PostScript output in enhanced text mode. This is necessary
9465 for Shift-JIS character encoding to work in enhanced mode (the non-
9466 enhanced mode already does this). Bug report #998479.
9468 2004-08-13 Ethan Merritt <merritt@u.washington.edu>
9470 * docs/gnuplot.doc: Re-word the filledcurves section according to
9471 suggestions from Petr Mikulik.
9473 * term/post.trm: Rename new option once again: set term post {level1}
9474 (naming history: nolevel2 -> ai -> level1). Audit code to confirm that
9475 in fact it excutes only commands required by PostScript Level 1.
9477 * src/save.c (save_tics) src/show.c (show_tics): Save tic level for
9478 each explicit user-added tic. Fixes bug #1008869.
9480 2004-08-12 Ethan Merritt <merritt@u.washington.edu>
9482 * term/post.trm: Rename 'nolevel2' option to 'ai', since its primary
9483 use may be to generate output compatible with Adobe Illustrator.
9485 2004-08-11 Ethan Merritt <merritt@u.washington.edu>
9487 * src/gplt_x11.c (exec_cmd): Set line properties to CapRound, JoinRound
9488 while drawing plot symbols. This works around a very odd bug that
9489 causes the symbols to be drawn incorrectly for some X-server settings.
9490 Also modify plot symbol code so that the symbols are always drawn with
9491 a 1:1 aspect ratio (crosses always fit in a square) rather than
9492 tracking the aspect ratio of the current plot window.
9494 2004-08-10 Ethan Merritt <merritt@u.washington.edu>
9496 * src/set.c (parse_colorspec): Allow people to set the text color
9497 to background (tc lt -2) if they really want to.
9499 2004-08-09 Ethan Merritt <merritt@u.washington.edu>
9501 * src/command.c: Remove unused prototype.
9503 * src/getcolor.c: Conditionally remove unused prototype during
9504 compilation of gnuplot_x11.
9506 * src/plot2d.c (eval_plots) src/plot3d.c (eval_3dplots)
9507 src/set.c (set_tic_prop): Continue replacement of isstring +
9508 m_quote_capture with try_to_get_string().
9510 * src/command.c (history_command): Code cleanup; convert to use
9511 try_to_get_string(). Code is still full of little memory leaks.
9513 * term/post.trm: Fix '%' characters in output format.
9515 2004-08-08 Ethan Merritt <merritt@u.washington.edu>
9517 * src/util.c src/util.h: New routine try_to_get_string() that combines
9518 isstring() and m_quote_capture(). The intent is to switch call sites
9519 over to using this new routine, and then extend it to handle string
9520 variables as well as quoted inline string constants.
9522 * src/contour.h: Revised declaration of contour_format[].
9524 * src/set.c src/command.c: Begin wholesale replacement of isstring()
9525 and m_quote_capture/quote_string with new routine try_to_get_string().
9527 2004-08-07 Ethan Merritt <merritt@u.washington.edu>
9529 * src/set.c (set_print set_output): Do not chop whitespace from the
9530 front of input string; it causes a segfault when the string is freed.
9531 If we really need to strip whitespace from filenames, it should be done
9532 in a routine shared by all callers.
9534 2004-08-06 Ethan Merritt <merritt@u.washington.edu>
9536 * term/graphics.c (place_arrows): Restore default text color after
9537 drawing all the arrows. Fixes bug #1004765.
9539 2004-08-02 Ethan Merritt <merritt@u.washington.edu>
9541 * term/gd.trm src/term.h configure.in src/show.c (show_version):
9542 GIF support is back in libgd as of version 2.0.28 (July 2004).
9543 At last we can use the same driver for png, gif, and jpeg.
9545 * term/gif.trm term/png.trm: Remove these old drivers.
9547 * src/makefile.all docs/Makefile.in: And remove them as make targets.
9549 * src/command.h src/command.c (load_command): Remove macro that was
9550 used in only one place; clean up code order as prep for applying
9551 string variable patches.
9553 2004-08-01 Ethan Merritt <merritt@u.washington.edu>
9554 Harald Harders <h.harders@tu-bs.de>
9556 * term/post.trm: Introduce a boolean value PSLevel2 into the PostScript
9557 prolog, and use it to determine whether pattern-fill is defined using
9558 PostScript Level 2 primitives or via a Level 1 solid fill. Introduce a
9559 corresponding option 'set term post ... {no}level2'. Setting level2
9560 to false either via 'set term' or by editing the output PostScript file
9561 accommodates older printers and older versions of Adobe Illustrator.
9563 2004-07-31 Harald Harders <h.harders@tu-bs.de>
9565 * term/post.trm (PS_common_init PS_put_text ENHPS_put_text):
9566 Check for black text only option in the PostScript code itself,
9567 rather than at the time the plot is generated. This allows you to
9568 change your mind later by editing one line in the PostScript file.
9570 2004-07-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9572 * src/show.c (show_key): Fix memory leak by making the variable in
9573 question a local to the switch case that uses it.
9574 (show_styles): Remove const-ness modifying cast.
9576 * src/save.c (save_data_func_style): Marked pointer argument
9579 * src/save.h (save_data_func_style): Prototype updated
9582 2004-07-29 Ethan Merritt <merritt@u.washington.edu>
9584 * docs/gnuplot.doc: Fix the alphabetical order of plot style
9587 2004-07-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9589 * src/util.c (PRINT_SPACES_UNDER_PROMPT): Protect against
9592 2004-07-27 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9594 Bugfix: caret position of error messages in multiplot modes was
9597 * src/util.c (current_prompt): New variable holding the currently
9599 (PRINT_SPACES_UNDER_PROMPT): Use current_prompt instead of global
9600 PROMPT macro. Use a pointer loop instead of a counter.
9601 (PRINT_SPACES_UNDER_PROMPT, PRINT_SPACES_UPTO_TOKEN): Enclosed
9602 macro body in do .. while(0).
9603 (os_error, int_error, int_warn): Use current_prompt instead of
9604 global macro PROMPT.
9606 * src/util.h (current_prompt): Declare.
9608 * src/command.h (PROMPT): Moved this global macro into command.c.
9610 * src/command.c (PROMPT): Moved macro to here.
9611 (read_line) [VMS]: Update new global variable current_prompt.
9612 (read_line) [!VMS]: Likewise.
9614 2004-07-25 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9616 Code style changes: get rid of register keywords. Don't put
9617 parens around simple variables or term->element names.
9619 * src/graphics.c (boundary): If bmargin was set by user, key below
9620 should not modify ybot. Reindented.
9622 (key_cols): Made local to boundary(), the only function using it.
9624 2004-07-24 Ethan Merritt <merritt@u.washington.edu>
9626 * src/parse.c (cleanup_udvlist): Fix memory leak; if udv structure
9627 is freed, free its dynamically allocated name also.
9629 * src/command.c (print_set_output): Fix memory leak; free old
9630 filename before setting a new one.
9632 * src/plot3d.c: Remove unnecessary #include "plot2d.h".
9634 2004-07-22 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9636 * src/util.h (os_error, int_error, int_warn, graph_error):
9637 Reverted change to prototypes for non-ANSI case back from (void)
9640 * src/fit.c (Dblfn): Likewise.
9642 2004-07-21 Ethan Merritt <merritt@u.washington.edu>
9644 * src/graphics.c (plot_bars plot_betweencurves): If the current
9645 terminal does not support filled_polygons, then fall back to
9646 yerrorbars plot style as per the documentation.
9648 2004-07-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9650 * term/post.trm (PS_make_header): Moved prototype into PM3D-only
9653 2004-07-21 Lars Hecking <lhecking@nmrc.ucc.ie>
9655 * demo/Makefile.am.in: Add labelplot.pdb and nearmap.csv to
9658 2004-07-19 Ethan Merritt <merritt@u.washington.edu>
9660 * src/graphics.c (do_plot): Write the key titles using
9661 write_multiline() rather than calling term->put_text() directly.
9663 * src/set.c (set_key): Fix order-dependence of 'set key' command.
9665 2004-07-18 Ethan Merritt <merritt@u.washington.edu>
9667 * term/pdf.trm: Update "Creator: " field to report version 4.1
9669 * term/post.trm: Petr's optimized format for solid pm3d quadrangles
9670 can be generated even outside the pm3d code, so the \h macro it uses
9671 must be defined in the header regardless of whether pm3d is in use.
9673 2004-07-17 Ethan Merritt <merritt@u.washington.edu>
9675 * term/post.trm (PS_filled_polygon): Remove extraneous gsave
9676 introduced by previous patch, which fixes the observed slowdown.
9678 2004-07-16 Ethan Merritt <merritt@u.washington.edu>
9680 * term/post.trm (PS_filled_polygon): The polygon fill code was
9681 mis-nesting gsave/grestore pairs, leading to several rather odd
9682 results. Fixes bug #992565 and also the loss of color information
9683 in pattern-filled fillcurves.
9685 * term/post.trm (PS_filled_polygon): Restore Petr's preferred
9686 compact format for the quadrangles that make up a pm3d surface,
9687 and add a gsave/grestore pair around the fill command. Fixes the
9688 moiré effect observed in ghostscript/gv with antialiasing enabled.
9689 Downside: takes longer to render; noticeable on a slow machine.
9691 2004-07-15 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9693 * term/fig.trm (FIG_arrow): Use actual linetype variables rather
9694 than those in FIG_line --- those are only set by FIG_vector, which
9695 isn't being called by FIG_arrow.
9697 2004-07-13 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9699 * src/show.c (show_version): Removed text about backwards
9700 compatibility of pre-4.0 syntax from startup message.
9702 * term/x11.trm (transmit_gradient): Made static. Missing
9705 * term/post.trm: General CodeStyle cleanup.
9706 (ps_fontfile_def): Made static.
9707 (PS_make_header): made static.
9709 * term/gd.trm (png_smooth_color): Made static.
9711 * src/variable.c (fontpath_tbl): All 5 instances made static.
9713 * src/util.h (chr_in_str): Unused, prototype commented out.

9717 * src/term_api.h (change_term): Removed prototype from here.
9719 * src/term.c (enhanced_recursion): Made static.
9720 (change_term): Made static. Prototype moved here from term_api.h.
9721 (term_count): Unused, commented out. Removed GP_INLINE flag.
9723 * src/specfun.c (merror, erf): Made static.
9725 * src/set.c (pm3d_last_set_palette_mode): Made static.
9726 (parse_histogramstyle): Made static.
9728 * src/save.h: Added missing #include "axis.h".
9730 * src/save.c: Moved #include "axis.h" to header.
9732 * src/plot2d.c (histogram_range_fiddling): Made static.
9734 * src/mouse.c (usual_special_keys): Made static.
9736 * src/misc.c (recursivefullname): Added missing prototypes.
9737 (arrow_use_properties): Made static. Moved prototype here, from
9740 * src/graphics.c (place_histogram_titles, style_from_fill): Made
9743 * src/gplt_x11.c (process_configure_notify_event): Added missing
9745 (getMultiTabConsoleSwitchCommand): Fixed used of __PROTO() macro
9748 * src/getcolor.h: Added missing #include "color.h".
9749 (color_components_from_gray, calculate_color_from_rgb_formulae,
9750 color_to_str, str_to_color, rgb255_from_gray): Removed prototypes.
9752 * src/getcolor.c: Removed #include "color.h" --- done in
9753 getcolor.h now. Massive reindentation and CodeStyle cleanup.
9754 (color_components_from_gray, color_to_str, str_to_color): Made
9755 static. Prototypes moved in here, from getcolor.h.
9756 (calculate_color_from_formulae): Added missing prototype.
9757 (rgb255_from_gray): Unused, commented out.
9759 * src/gadgets.h (suppressMove): Unused, commented out.
9761 * src/gadgets.c (suppressMove): Unused, commented out.
9762 (draw_clip_line): Usage of suppressMove commented out.
9764 * src.fit.c(log_axis_restriction): Added missing prototype.
9766 * src/datafile.c (df_no_tic_specsm, df_column,
9767 df_parse_string_field): Made static.
9769 * src/command.c (capture_filename_and_pfopen): Added missing
9772 2004-07-10 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9774 * src/unset.c (unset_mtics): Renamed to unset_minitics, for
9776 (unset_month_day_tics): New function, to implement 'unset xmtics'
9778 (unset_command): Change all calls of unset_mtics to the new name.
9779 Implement previously missing 'unset xmtics' and friends by calling
9782 2004-07-09 Ethan Merritt <merritt@u.washington.edu>
9784 * src/util.c (parse_esc): Limit size of octal constants to 3 chars,
9785 possibly with a leading 0. This prevents consuming additional
9786 numerical characters from input stream.
9788 2004-07-08 Ethan Merritt <merritt@u.washington.edu>
9790 * src/gplt_x11.c (pr_font): Before falling back all the way to a fixed
9791 width font, try two common scalable fonts (helvetica, arial) as a last
9792 resort. Fixes bug #963211 on systems with either of these fonts.
9794 * src/gplt_x11.c (exec_cmd) term/gd.trm (PNG_point): Apply current
9795 linewidth to point symbols.
9797 * src/misc.c (get_style): Add new styles 'labels' and 'histograms' to
9798 the error message listing possible styles.
9800 * configure.in: Make --enable-histograms the default.
9802 * demo/all.dem: Add fillbetween, datastrings, and histograms demos.
9804 2004-07-08 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9806 * term/pdf.trm (PDF_init): Call PDF_open_file() instead of
9807 no longer existing function PDF_open_fp().
9809 * demo/datastrings.dem, demo/starmap.dem: Replaced Windows-only
9810 font name Arial by Helvetica.
9812 * docs/gnuplot.doc: Remove whitespace-only lines.
9813 (contour): Remove outdated info on limited number of contour
9816 2004-07-08 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9818 Integrated SF patch #976546 by Stephane Barbaray, with some
9819 additional changes by me.
9821 * term/emf.trm: Reindented. Ancient hacks for NeXT and <assert.h>
9823 (EMF_PX2HM): Changed to 26.37.
9824 (EMF_HCHAR, EMF_VCHAR): Changed by factors 0.6 and 1.3,
9826 (EMF_set_font): Multiply recomputed values for h_char and v_char
9827 by 0.6 and 1.3, respectively.
9828 (EMF_setfont): Output correct font struct size with some fields
9830 (EMF_graphics): Divide by EMF_PX2HM instead of 20. Make reference
9831 device 1024x768 pixels, 270x200 mm.
9832 (EMF_put_text): Use ExtTextOutA instead of ExtTextOutW, include
9834 (EMF_point): Disable special treatment of negative point types,
9836 (EMF_set_pointsize): Don't divide base size by 2.
9838 2004-07-07 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9840 * src/win/wtext.c (WndTextProc): Fix bug introduced during
9841 ANSI-fication operation.
9843 2004-07-05 Ethan Merritt <merritt@u.washington.edu>
9845 * src/gplt_x11.c: Rework event-handling subroutines so that the
9846 intermediate window resize and redraw events are skipped if possible.
9847 This reduces the hysteresis when the window is resized by dragging.
9848 Patch by Jay Painter <jpaint@u.washington.edu>.
9850 2004-07-05 Ethan Merritt <merritt@u.washington.edu>
9852 * src/graph3d.c (place_labels3d place_arrows3d get_arrow3d): Test for
9853 wrap-around of negative coordinates when converted to unsigned screen
9854 coordinates by map3d_position. If wrap-around has occurred, then skip
9855 this label or arrow when drawing the 3D plot. This really should be a
9856 general test for out-of-bounds, but the simple test at least catches
9857 some potentially fatal errors that have already happened.
9859 2004-07-04 Ethan Merritt <merritt@u.washington.edu>
9861 * configure.in: --enable-histograms
9863 * demo/histograms.dem demo/histograms2.dem demo/immigration.dat:
9864 Demonstration files for 'plot with histograms'

9870 src/plot2d.c src/save.c src/set.c src/show.c src/tables.c
9871 src/tables.h src/unset.c: Integrate SourceForge patchset #606169.
9873 New plot style "with histograms" produces a bar chart from a sequence
9874 of data columns in parallel. Each element of the `plot` command must
9875 specify a single input data source (e.g. one column of the input file),
9876 possibly with associated tic values or key titles. Three styles of
9877 histogram layout are currently supported.
9878 set style histogram clustered {gap <gapsize>}
9879 set style histogram rowstacked

9886 term/cgm.trm term/pdf.trm term/svg.trm:
9887 Add #ifdef PM3D where appropriate to allow building without PM3D.
9889 * src/gp_types.h: This patch starts to make term->filled_polygon
9890 and filledcurves independent of PM3D.
9892 * src/term.c (test_term): Fix broken test of filled_polygon.
9894 * src/graphics.c (plot_betweencurves, fill_between, bound_intersect):
9895 ANSIfication of function definitions.
9897 2004-07-04 Hans-Bernhard Broeker <broeker@accip02.physik.rwth-aachen.de>
9899 * src/set.c (set_arrow): Fix parsing of 'rto' vs. 'to'. Thanks to
9900 Shigeharu Takeno for spotting this.
9902 2004-07-03 Ethan Merritt <merritt@u.washington.edu>

9918 src/show.c src/tables.c src/util.c src/util.h:
9919 Integrate the "datastrings" patchset (SourceForge #595850).
9921 New plot style "with labels" will read a string, possibly delimited
9922 by quotes, from the data file and place it at the x, y, {z}
9923 coordinates specified. E.g.:
9924 plot 'datafile' using 1:2:3 with labels
9925 splot 'datafile' using 7:8:9:4 with labels
9927 New internal functions specific to the 'using' option that specify
9928 that string data from a datafile column is to be used for tic labels,
9929 or that string data from a datafile row is to be used for plot key
9931 plot '-' using 0:2:xticlabels(1) title 2 with boxes
9937 This will plot a histogram with each an x-axis tic label under
9938 each box: "Jan", "Feb" etc. The plot key will list the plot with

9943 * gnuplot/src/gp_types.h gnuplot/src/graphics.c gnuplot/src/plot2d.c:
9944 Rename PLOT_STYLE_HAS_BOXES to PLOT_STYLE_HAS_FILL since it now
9945 applies to objects other than boxes.

9950 src/misc.c src/plot2d.c src/pm3d.c src/set.c src/tables.c src/tables.h
9951 src/term_api.h src/term.c:
9953 New capabilities for filledcurves plot style.
9954 (1) New options "above" and "below" to limit filled area to one side of
9955 the bounding line or second curve.
9956 (2) New ability to fill area between two curves (triggered if 3 input
9957 columns are given. E.g. `plot "data" using 1:2:3 with filledcurves`
9958 (3) Apply current fill style to filledcurves (requires terminal support
9959 in term->filled_polygon).
9961 * demo/fillbetween.dem docs/gnuplot.doc: documentation and demo file
9963 * term/cgm.trm term/gd.trm term/pdf.trm term/post.trm term/svg.trm
9964 term/x11.trm: Modified filled_polygon() to apply fill style passed in
9965 the color structure of the first vertex.
9967 * src/gplt_x11.c: Back-end support for applying explicit fill style
9968 to filled_polygon. Beware of incompatibility with early versions.
9970 2004-07-02 Ethan Merritt <merritt@u.washington.edu>
9972 * term/post.trm: Minor cleanup of enhanced text "phantom box" macros.
9974 2004-07-02 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9976 * PATCHLEVEL, VERSION: Changed to version 4.1, patchlevel 0.
9978 * src/version.c (gnuplot_version, gnuplot_patchlevel,
9979 gnuplot_date): Updated by regenerating the file.
9981 * docs/gnuplot.doc, docs/titlepag.ms, docs/doc2texi.el: Update
9982 number in the title pages.
9984 * docs/gnuplot.texi: Regenerated.
9986 2004-07-01 Ethan Merritt <merritt@u.washington.edu>
9988 * src/fit.c: #include gp_time.h is now necessary.
9990 2004-07-01 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
9992 * PATCHLEVEL: Raised to 2 to mark post ANSI-fication status.
9994 * src/version.c (gnuplot_patchlevel, gnuplot_date): Updated.
9996 * ChangeLog, ChangeLog.0: Cycled the ChangeLog. Entries before
9997 the 4.0.0 release are now in ChangeLog.0, newer ones in ChangeLog
10000 * src/util.c (mant_exp): Modulo results can be negative.
10003 2004-06-30 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10005 * PATCHLEVEL: Raised to 1 in preparation of ANSI-fication.
10007 * src/version.c (gnuplot_patchlevel, gnuplot_date): Updated.
10008 (RELEASE_VERSION): Turn off.
10010 * INSTALL: removed pointless copy of startup banner screen.
10012 * docs/gnuplot.texi: Regenerated.
10014 * term/post.trm (PS_linewidth_last): New variable.
10015 (PS_graphics, PS_point, PS_fillbox): Initialize it.
10016 (PS_linetype): Call PS_FLUSH_PATH here, too.
10017 (PS_linewidth): Don't break the path if the new linewidth is the
10018 same as the cached value PS_linewidth_last. Do a PS_FLUSH_PATH
10021 * term/debug.trm (DEBUG_arrow): Fix type of 'head' argument.
10023 * src/hidden3d.c (in_front): Slight change to handling of points
10024 falling onto edges of triangles in 2D. Reindentations.
10026 * src/fit.c (log_axis_restriction): New function to output the
10027 actual state of the axis ranges, as optionally modified by range
10028 specified in the fit command line.
10029 (fit_command): Use it.
10031 * src/graphics.c (plot_bars): Reindentation.
10033 * src/util.c (mant_exp): Reindentation.
10035 * src/plot3d.c (print_3dtable): #undef OUTPUT_NUMBER earlier.
10037 2004-06-24 Ethan Merritt <merritt@u.washington.edu>
10039 * src/mouse.c (event_reset): If 'pause mouse' terminates because
10040 the plot window is closed, insert an extra '\n' into the input
10041 stream so that the first character of the subsequent command is
10044 2004-06-20 Ethan Merritt <merritt@u.washington.edu>
10046 * src/mouse.c (event_reset), src/command.c (pause_command),
10047 docs/gnuplot.doc: Set MOUSE_KEY to -1 when the "pause mouse {key}"
10048 command is issued; if it is still -1 when checked later, then the
10049 calling program may assume that no mouse input was successfully
10052 * src/command.c (pause_command): Change the test for legality of
10053 "pause mouse" command from "if (term_initialised)" to "if
10054 (mouse_setting.on)". Really it should test whether the current
10055 terminal supports mousing at all, but we don't yet have such a
10058 * src/gplt_x11.c (process_event): Translate keystrokes using
10059 XLookupString() rather than XKeycodeToKeysym(). This method
10060 handles characters produced using shift, alt, or other multi-key
10063 * src/graphics.c (plot_f_bars plot_c_bars), term/gd.trm
10064 PNG_options): Make sure that the tic size is greater than zero.
10066 2004-06-20 Petr Mikulik <mikulik@physics.muni.cz>
10068 * src/graph3d.c (key_sample_line_pm3d key_sample_point_pm3d):
10069 Fixed wrong step for negative palette.
10071 * src/color.c (set_color) src/command.c (test_palette_subcommand)
10072 src/show.c (show_palette_palette): Removed useless comments.
10074 2004-06-19 Petr Mikulik <mikulik@physics.muni.cz>
10076 * src/color.c (set_color, draw_inside_color_smooth_box_bitmap)
10077 src/pm3d.c (cb2gray): Invert gray in routine pm3d.c:cb2gray(cb),
10078 instead of color.c:set_color(gray). The latter is now just setting
10079 term->set_color(gray) if the terminal supports set_color() API.
10081 * graph3d.c (do_3dplot): Fixed set_color(z2cb( cb2gray(cntrs->z))
10082 to set_color(cb2gray( z2cb(cntrs->z) )).
10084 * gadgets.c (apply_textcolor): Take care of positive/negative
10085 palette for 'set label ... textcolor frac ...'.
10087 2004-06-17 Ethan Merritt <merritt@u.washington.edu>
10089 * src/gplt_x11.c (process_event): Send a GE_reset event back to gnuplot
10090 if the current plot window is closed.
10091 * src/mouse.c (event_reset): Terminate paused_for_mouse state whenever a
10092 GE_reset event is received.
10094 2004-06-16 Ethan Merritt <merritt@u.washington.edu>
10096 * src/gplt_x11.c (mainloop): Yet another tweak to the mouse timing code.
10097 This one reduces mouse-tracking hysteresis on systems that claim to have
10098 usleep() but in fact have much coarser timing.
10100 2004-06-16 Petr Mikulik <mikulik@physics.muni.cz>
10102 * src/save.c: Save log cb axis (bugfix).
10104 2004-06-14 Petr Mikulik <mikulik@physics.muni.cz>
10106 * src/mouse.c: Do not start zooming during 'pause mouse'.
10108 2004-06-12 Ethan Merritt <merritt@u.washington.edu>
10110 * show.c (show_datafile): Provide missing show commands for suboptions
10111 "show datafile {separator|comment|missing}".
10113 2004-06-12 Ethan Merritt <merritt@u.washington.edu>
10115 * datafile.h: define DF_MISSING as a return code from df_readline().
10116 * datatile.c (df_readline): If a data field contains the missing data
10117 string, return DF_MISSING rather than DF_UNDEFINED.
10118 * fit.c (fit_command): Explicitly ignore DF_MISSING data.
10119 * plot2d.c (get_data): Explicitly test for data marked DF_MISSING
10120 but treat it the same as DF_UNDEFINED.
10121 * plot3d.c (get_3ddata): Explicitly test for data marked DF_MISSING
10122 but treat it the same as DF_UNDEFINED.
10124 These are trivial changes that do not affect the existing behavior of
10125 gnuplot. However, the core routines in plot2d and plot3d now have the
10126 information needed to treat missing data differently depending on the
10127 plot style if desired.
10129 2004-06-06 Ethan Merritt <merritt@u.washington.edu>
10131 * src/command.c src/command.h src/mouse.c src/gplt_x11.c
10132 term/x11.trm docs/gnuplot.doc docs/gnuplot.texi:
10133 `pause mouse keypress` option behaves exactly as `pause mouse` except
10134 that the pause can be terminated by a keystroke while the plot window
10135 has focus. On return, the variable MOUSE_KEY contains the mouse button
10136 number if the pause terminated on a mouse click, otherwise it contains
10137 the key code of the key that was pressed. Normal ascii characters will
10138 return their ascii code; other keyboard keys are assigned codes from a
10139 table in mousecmn.h. The command may be shortened to `pause mouse key`.
10141 2004-06-04 Petr Mikulik <mikulik@physics.muni.cz>
10143 * src/mouse.h src/mousecmn.h src/mouse.c: Split array special_keys[] of
10144 of key names and key codes into special_keys[] and usual_special_keys[],
10145 so that "usual" keys (like BackSpace, Tab, Enter, Return, Escape, Tab,
10146 Delete) can have their "usual" keycodes instead of those >=1000.
10147 Changed lookup_key() and bind_fmt_lhs() in mouse.c to look into both
10148 arrays. This does not change any functionality of the current version
10149 of gnuplot, but will help new future features (like "pause mouse key").
10151 2004-06-03 Ethan Merritt <merritt@u.washington.edu>
10153 * term/emf.trm (EMF_linewidth): Force re-evaluation of line
10154 characteristics when the linewidth changes; otherwise the new width
10155 is ignored until some other property changes as well.
10157 2004-06-01 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10159 * demo/fillcrvs.dem: Add text to pause -1 prompts.
10161 * docs/gnuplot.doc (plot datafile using): Document restrictions of
10162 'using' format-strings.
10164 * src/datafile.c (valid_format): Check that there's at least one
10165 actual %lf format in the format string, and no more than 7,
10166 because the scanf() that uses the format supplies only 7 arguments
10168 (plot_option_using): Change error message to reflect new status
10169 output of valid_format().
10171 2004-05-28 Petr Mikulik <mikulik@physics.muni.cz>
10173 * src/getcolor.c (color_components_from_gray): Test gray value for
10174 being in range [0;1].
10176 2004-05-27 Ethan Merritt <merritt@u.washington.edu>
10178 * src/gplt_x11.c (PaletteSetColor): Test for overflow of index
10179 derived from color ramp calculation. Is this algorithm really correct?
10181 2004-05-27 Petr Mikulik <mikulik@physics.muni.cz>
10183 * term/post.trm (PS_make_header): Change definition of /pm3dround
10184 to fix color mapping with 'set palette maxcolors'.
10186 * src/win/wgraph.c (drawgraph): Change call from rgb255_from_gray() to
10187 rgb255maxcolors_from_gray(). Fixes color mapping with 'set palette
10190 2004-05-26 Ethan Merritt <merritt@u.washington.edu>
10192 * src/gplt_x11.c (PaletteSetColor): Fix off-by-one error in indexing
10193 color ramp of gray values.
10195 * src/mouse.c (do_event): Allow font and terminal size information to
10196 be processed while in multiplot mode. See bug #955081.
10198 2004-05-26 Petr Mikulik <mikulik@physics.muni.cz>
10200 * src/getcolor.h src/getcolor.c: New routines rgb1maxcolors_from_gray()
10201 and rgb255maxcolors_from_gray().
10203 * term/aquaterm.trm (AQUA_set_color) term/pdf.trm (PDF_set_color):
10204 Change call from rgb1_from_gray() to rgb1maxcolors_from_gray(). Fixes
10205 color mapping with 'set palette maxcolors'.
10207 * svg.trm (SVG_set_color): Change call from rgb255_from_gray() to
10208 rgb255maxcolors_from_gray(). Fixes color mapping with 'set palette
10211 2004-05-26 Petr Mikulik <mikulik@physics.muni.cz>
10213 * src/mouse.c (event_buttonpress): Don't start zooming box if replot is
10216 2004-05-24 Ethan Merritt <merritt@u.washington.edu>
10218 * src/gplt_x11.c (exec_cmd): Flush polyline to X-server when it reaches
10219 half the maximum single request size supported on the current display.
10221 * term/dumb.trm term/gd.trm term/pfg.trm term/x11.trm: The enhanced text
10222 overprint parameter was used as an (int) in some drivers, even though it
10223 is declared as a TBOOLEAN. Change it to (int) everywhere.
10225 2004-05-24 Petr Mikulik <mikulik@physics.muni.cz>
10227 * src/pm3d.c src/term.c term/hpljii.trm: SF bug #953887 non-portable C
10228 code (prototypes & TBOOLEAN): input parameter for routines cannot be
10229 char, they must be int.
10231 2004-05-21 Ethan Merritt <merritt@u.washington.edu>
10233 * src/gplt_x11.c (mainloop): Add a 100 usec delay to the event flush
10234 loop, so that if the other end of the pipe is jammed (gnuplot STOPPED)
10235 it doesn't monopolize CPU cycles. Fixes user-triggered error condition
10236 reported in bug #930426.
10238 2004-05-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10240 * src/graphics.c (plot_boxes): Clip lower border of
10241 boxxyerrorbars, too.
10242 (do_plot): Regrouped master switch over plot types. Draw box
10243 first in BOXERROR mode, to keep the lower part of the errorbar
10246 * src/util.c (mant_exp): Extend technique for rounding exponents
10247 depending on the printf format precison of the mantissa to format
10248 specifiers %l and %L used for log bases other than 10. Fixes SF
10251 2004-05-20 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10253 * term/debug.trm (DEBUG_arrow): Fix type of 'head' argument
10254 overlooked in earlier global change.
10256 * src/plot2d.c (get_data): Fix mininum number of columnts for
10257 boxerrorbars style. Fixed handling of 4-column boxerrorbars in
10258 case of "set boxwidth -2" to match the documentation.
10260 * src/graphics.c (plot_impulses): Fix bug in clipping of impulses
10261 for out-of-range points. Was using an integer value to store a
10262 floating-point temporary number.
10264 * src/plot2d.c (print_table): Make the table terminal output two
10265 blank lines at the end of each curve_points structure, to allow
10266 selection of individual datasets via the 'index' option.
10268 * docs/doc2texi.el (d2t-handle-html): Handle anchor-only <a> tags
10269 more sensibly: output them to the texinfo file as a @c comment.
10270 Patch from Shigharu Takeno.
10272 * docs/gnuplot.texi: Regenerated.
10274 2004-05-19 Petr Mikulik <mikulik@physics.muni.cz>
10276 * src/mouse.c: Fix broken zoom history with a log axis.
10278 2004-05-17 Petr Mikulik <mikulik@physics.muni.cz>
10280 * src/mouse.c src/win/wpause.c: Support for "pause mouse" in Windows
10283 2004-05-16 Ethan Merritt <merritt@u.washington.edu>
10285 * src/graphics.c (boundary): prevent plot from flipping upside-down
10286 if the title or key take up too much vertical space.
10288 * term/post.trm: Add explicit default case to encoding switch.
10290 2004-05-09 Ethan Merritt <merritt@u.washington.edu>
10292 * term/x11.trm: Reduce time delay in waitforinput() from 1 sec
10295 2004-05-09 Petr Mikulik <mikulik@physics.muni.cz>
10297 * docs/gnuplot.doc src/term_api.h src/term.c term/post.trm: Add support
10298 for CP1250 character encoding (Central and Eastern Europe encoding on
10301 2004-05-09 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10303 * config/README: Clean up some of the descriptions.
10305 2004-05-07 Ethan Merritt <merritt@u.washington.edu>
10307 * term/x11.trm: Add an explicit "noenhanced" option to set term x11,
10308 since otherwise once you select enhanced text you cannot turn it off
10311 2004-05-07 Franz Bakan <fbakan@users.sourceforge.net>
10313 * src/os2/gclient.c: SF bug #940596. Match menu items "GnuplotPM ->
10314 Mouse -> Coords format -> ..." to the text actually printed.
10316 2004-05-06 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10318 * src/win/wtext.c (WndTextProc): Fix unbelievably old
10319 long-standing bug: dragging the scroll bar "thumb" around didn't
10320 work, because the method of acccessing the position was completely
10323 2004-05-04 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10325 * src/set.c (set_range): Fix SF bug #946900: buggy interaction of
10326 'set view map' with 'set yrange'.
10327 (set_view): Make error message string variables static and const
10328 to preserve some stack.
10330 2004-05-03 Ethan Merritt <merritt@u.washington.edu>
10332 * src/mouse.c, term/x11.trm: Move handling of mouse click after
10333 'pause mouse' from mouse.c to x11.trm. This removes an otherwise
10334 unnecessary do_string("replot") from mouse.c, and instead adds an
10335 explicit check for mouse button release in X11_waitforinput().
10337 * demo/mousevariables.dem: Add a comment after final pause command.
10339 * src/set.c src/unset.c: Call gp_strdup() rather than strdup() as
10340 otherwise the test in ./configure is pointless, and gnuplot fails
10341 to link on systems without strdup().
10343 * term/x11.trm: Redefine VMS-only macro to allow if/then/else
10344 constructs: GO(x) = do {} while (0)
10346 * src/show.c: Protect call to add_history() with a test for the
10347 presence of READLINE support.
10349 2004-04-30 Petr Mikulik <mikulik@physics.muni.cz>
10351 * docs/gpcard.tex: Remove duplicated X11 terminal entry.
10353 2004-04-29 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10355 * docs/gnuplot.doc: Fix description of default format being "% g"
10358 2004-04-26 Petr Mikulik <mikulik@physics.muni.cz>
10360 * docs/gnuplot.doc: New section "Gnuplot-defined variables". Reference
10361 function defined(x) from section "User-defined variables".
10363 2004-04-24 Ethan Merritt <merritt@u.washington.edu>
10365 * src/gplt_x11.c: Correct the placement of rotated text to account
10366 for the difference in x and y coordinate scaling. This greatly
10367 improves the rendering of rotated text in enhanced text mode.
10369 2004-04-22 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10371 * src/axis.c (set_cbminmax): Don't bail out if cbrange is empty.
10372 Let the caller handle it by auto-extending the range, as usual.
10374 * src/command.c (read_line): Fix bug where growing the line buffer
10375 interfered with handling of backslash-newline continuations.
10377 2004-04-21 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10379 * demo/Makefile.am.in (check-noninteractive, check-interactive):
10380 keep the previous $PATH at the end of the one set for running the
10381 newly built, not yet installed gnuplot. Needed so Cygwin binaries
10382 can find Cygwin1.dll, even if it's not installed in the Windows
10385 2004-04-20 Hans-Bernhard Broeker <broeker@physik.rwth-aachen.de>
10387 * docs/gnuplot.texi: Regenerated.
10389 * docs/gnuplot.doc: Fixed missing leading blanks broken during URL
10392 * docs/Makefile.in ($(srcdir)/gnuplot.texi): Fix missing blank in
10395 2004-04-17 Ethan Merritt <merritt@u.washington.edu>
10397 * term/x11.trm: Clear all I/O locks when X11_reset is called.
10398 This is a more generic fix for the problem addressed by the patch
10399 of 2004-04-13, and covers cases such as a remote X-server failing
10400 to respond. Even without this patch the connection will eventually
10401 timeout, but with the patch you can ctrl-C out rather than waiting.
