hi,
I'm using polar bars to plot windroses. Since the 0.98.5 version i have
some issues with the plots.
The 0° bar is not displayed in the good way. This bar is
located between -0.26 radian and 0.26 radian but it is printed
counterclockwise.
It was working perfectly with matplotlib version 0.98.3. I just switched to
version 0.98.5 because of the NaN bug of the previous version.
The bug was fixed on Jan. 2. Can you install mpl from svn? Or just
patch your installation with the attached diff? (Only the first hunk is
critical for the bug.)

Any idea how i could make it work again ?
Ty!!
