I'm trying to generate rose plots (circular histograms) using MPL but have been unable to find a straight forward way to do it. I want to take the polar_bar.py example and modify it to use the geographic rather than the mathematical convention for measuring angles, that is 0 is at the top of the plot and increasing clockwise. It seems like this should be possible using Transformations but I am at a loss for how to begin. Any hints would be greatly appreciated. Thanks,  Jed Frechette jdfrechette.alturl.com
