matplotlib Code

Set svn:ignore on the subdirectories within examples (except data)

removed debug savefig from image demo

fix for ps renderer dpi/imagedpi confusion

Add support for flipping which side of the barb the features are drawn. Useful to the meteorologists in the southern hemisphere plus anyone who might have an aesthetic preference.

support mouse wheel in wx

Fix wx start/stop event loop

Update barb_demo.py to exercise more of the possible parameters for wind barb plots. Replace some confusing code for passing in the data with more explicit arrays. Also, make the data array for the arbitrary grid non-square so that proper dimensioning can be seen. Remove mysterious windows-styles line endings.

restored broken barb demo

converted barb demo to unix new lines

Added Barbs polygon collection (similar to Quiver) for plotting wind barbs. Added corresponding helpers to Axes and pyplot as well. (examples/pylab_examples/barb_demo.py shows it off.)
