Many moons ago Helge Avlesen (CCd on this email) sent me a contouring
routine for inclusion in matplotlib. I was too busy to get to it for
a while, and when I did look at it, I was concerned by the fact that
the lines were not smooth - if you plot a connected line they line
jumps from side to side. But it does get the contour right, and is
implemented in pure numeric, and so it occurs to me that it might be
easier to fix this problem than start from scratch. Perhaps Helge or
one of you has some insight into how to fix this.
I'm attaching a modified version of the tarfile Helge initially sent
me. I've included a script testkont_mpl.py that calls Helge's lib.
Change the '.' linestyle to '-' to see the problem I discussed.
