Octave uses gnuplot as its plotting program. The plplot bindings to=20
octave, besides the API entry points, also has octave scripts that=20
emulate most of the octave plotting commands. I had difficulties=20
emulating some gnuplot features, and some are even impossible to=20
emulate.

Gnuplot is interactive, and if you say "title blabla" the old title=20
will disappear and the one appears. The same if you change axis scales=20
or types, etc. This kind of features poses some problems. Not to talk=20
about the gnuplot "processing" features (minimization...)

I don't think that writing a program to emulate gnuplot should be a=20
target to plplot development. But gnuplot users could write it!
