9.8 Gnuplot

Pll command =gnuplot facilitate integration with gnuplot provided that gnuplot exists on the system. The gnuplot module must be imported in order to use this facility. This is done with =import("gnuplot").

The operand to =gnuplot is considered syntactically correct gnuplot-input and is channelized unchanged to gnuplot. The resulting output is converted to the png image format and included into the slide-show.

E.g.

=begin-gnuplot
set hidden3d
set view 60,30,1
set isosamples 60
splot [-2.5:2.5] [-2.5:2.5] (x**2 + 3*y**2)*exp(1-(x**2 + y**2))
notitle
=end-gnuplot
