[Matplotlib-users] Asking for help modifying a matplot windrose graphic using Python (:

[Guilherme A. M. <ga...@gl...>]

Hello guys.
I'm having a problem with a matplot graphic and I guess it can be easy for
Python experts to solve. Hope I'm not out of topic here.

Basically, I'm using this code...
http://matplotlib.org/examples/pylab_examples/polar_bar.html

... but I want to turn it in something like this graphic over here...

You see, where more than one bar pointing the same direction will be put
one over the other (the biggest in the base and the smallest at the top). I
assumed I had to put some function at this part of the code:

bars = ax.bar(theta, radii, width=width, bottom=0.0)

Turning Bottom into a function call somewhat related to the radii (bar
size) if both bars have the same theta (angle). Point is I'm having some
trouble doing that. I'm totally stuck, actually.

If not a complete solution, some tip would be apreciated.

Thank you very much!
