+# Though gnuplot is primarily a scientific plotting program, it can do a great
+# job of plotting finance charts as well. The primary challenge is the irregular
+# nature of financial time series. Stocks don't trade every day, so when you set
+# the x-axis to time gaps appear for non-trading days. Investors and traders
+# generally prefer that these gaps be omitted. Another challenge is that finance
+# charts are best presented in semi-log form (log y-axis, linear x-axis),
+# but gnuplot wants to span decades in its log scaling, something that stocks
+# rarely do. These and other challenges are met in finance.dem, a short
+# demonstration script that proves that gnuplot can really shine in this area.
+#
+# gnuplot plays a central role in our work. Almost all the graphs in "Bollinger
+# on Bollinger Bands" were plotted by gnuplot, many gnuplot visuals have
+# appeared on CNBC, our in-house analytics use gnuplot for visual display and
+# The Capital Growth Letter relies heavily on gnuplot for its charts.
+#
+# Finally, gnuplot is yet another successful demonstration of a powerful idea,
+# open source programming. Thanks to all who made gnuplot possible from the
+# earliest days to the present and to all those who will contribute in the
+# future. (Special thanks to Hans-Bernhard Broeker whose patience helped me to
+# climb the grade and to Ethan Merritt whose recent contributions have been
+# invaluable to our work.)
