[matplotlib-devel] zdir and offset features for 3d contourf
A fellow student approached me today wanting to know if matplotlib was able to produce a certain kind of 3d plot where a filled contour was placed on one of the axes panels. I knew it was possible with regular contours, but was surprised when I realized that the same feature wasn't available for contourf. So I wrote a patch to add that feature (and clean up a few documentation-related things). I also added an example script with examples/mplot3d/contourf3d_demo2.py. This is the image produced by the example: http://dl.dropbox.com/u/7325604/newcontourf3d.png This was committed in r8915. Enjoy!

On a related note, a considerable fraction of the mpl bug tickets on sourceforge are for mplot3d. For a while I was assigning them to Reinier Heeres, but I think he has been unable to get to them. I suspect some are actually quite simple to fix, and others may already have been fixed by work you have been doing on mplot3d. If you get a chance, please look through them and close any that can be closed. If there are any that you think you will be able to address, but not immediately, please assign them to yourself.

Re: [matplotlib-devel] [Python-modules-team] Bug#608942: python-matplotlib-doc: spaces in arguments of Sphinx ":param" field

When nx1 is None, a single nx-th column is specified. Otherwise location of columns spanning between nx to nx1 (but excluding nx1-th column) is specified. * ny1 (ny,) – same as nx and nx1, but for row positions. With the attached patch, I removed the space between those arguments, but at least it generates a correct list even tho it's a bit visually unpleasant.

[matplotlib-devel] Path.to_polygons problem

[matplotlib-devel] Recent sphinx and documentation images output format
Hi, as per recent sphinx (I got 1.0.6 where, and with 1.0.1 it worked fine), the image 'formats' is loaded as a unicode object, and so it's no more a str as previously identified in lib/matplotlib/sphinxext/plot_directive.py: the attached patch make the doc be buildable again with 1.0.6 and should be backportable.
