The 3D plot handling has never been very good; it's harder to work with PNG files from TeX than vector formats such as EPS or PDF. And with so many options for the graphics commands, it's hard to come up with defaults that will make users happy while still allowing some people to fiddle with them. The rendering, I think, is by Tachyon, not matplotlib. > P.S.

But that package doesn't work with XeLaTeX. I can add in a check for that. Dan -- --- Dan Drake ----- http://math.pugetsound.edu/~ddrake -------
