What can I answer here on "what is it?"? See for yourself
on my html page - I am not hiding anything. Far from being
finished (for example, the phase portrait type of plots
would be handy too) this little module demonstrate the
right level of Haskell abstraction and flexibility, I think.
Believe me, I tried very hard to find anything on gnuplot
vs. gif output: their faq, manual, etc. And I could not find
anything. If gnuplot has such capability than I am not the
one to blame but their own outdated documentation.
Being as lazy as anyone, I do not find writing this sort of
things exceedingly exciting. But once I have done it I really
enjoy the fruits of my labour, because this is exactly what I
wanted for my more serious work at hand, where Haskell program
is embedded in an engineering report (on seismic qualification
of certain scientific instrument). And for this the gnuplot
-- no matter how fancy it might be, is far from being the right
tool. Heck, I even consider sharing the report with the world
to help a bit with Haskell advocacy.
