I must disagree with you on this point. I agree that plotting WAS good
only for quick plots I think that since moving to having core graphics
in octave, I can produce production quality 2D plots using

We now (at least from version 3.0.3) have full control over line
widths & fonts, and mouse zooming. The only thing I was missing for my
last "publication quality" plot was control over ticklabel fonts. I
think that with some more effort the fltk backend will be up to speed
and provide even those.

As for VTK, from the examples on their page, I do not consider their
graphics "publication quality", and we are building on established
systems by using OpenGL which does most of the 3D work for us
