Similarly, PGPLOT works great as well. Almost all of my published
figures are generated using it. There is a python module called ppglot
that works with numeric and numarray, and only minor changes are needed
to make it work with numpy (I can send those changes if you want to
check them out). It is a fortran library with C-wrappers and python
around that, but it is still _very_ fast. I'm not sure how it handles
