That's a very nice example on the possible interactions between gretl
and gnuplot.
Something I couldn't have figured out by myself starting from scratch...
In fact, this proves that what is really needed is probably just to
improve the guide to show users how they can interact with gnuplot using
hansl.
Well, yes it's a nice example, but IMHO it really just shows Jack is
good at speaking gnuplotish. I mean there's a lot of printf overhead
etc. With temporary files you can basically do anything from within
gretl if you know the syntax of the external program, because you could
also call other programs (look up the keyword "shell" in the command help).
