Plotter based on JFreeChart for simple, general-purpose plotting from the shell
Consider this JWPlot configuration file (Java properties format):
examples/lines/jw.cfg
title = JWPlot
xlabel = ecks
ylabel = why
label.j.data = J
label.w.data = W
And these data files:
examples/lines/j.data
-6 4
-5.999 1
-1 1
-0.999 8
examples/lines/w.data
1 8
3 1
5 4
7 1
9 8
Run these command lines:
$ jwplot jw.eps jw.cfg j.data w.data
$ convert jw.eps jw.png
Get this output:
