matplotlib Code

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.)

added scikits.delaunay as matplotlib.delaunay, added griddata function to mlab.

Minor ginput_manual_clabel.py changes

Recommitting my changes to clabel to allow for manual labeling after fixing
problems with indexing identified by Eric Firing on 19 July 2008.

In addition, I have made the following changes:

1) Placed more comments in contour.py with the intention of eventually doing
a rewrite or restructuring of that code.

2) Added two pylab_examples: contour_label_demo.py that tests out some of the
more advanced things that can now be done with contour labeling, and
ginput_manual_clabel.py that demonstrates some uses of ginput,
waitforbuttonpress, and clabel(...,manual=True). The first of these has been
integrated into backend_driver.py, but the second cannot be because it
requires interaction.
