Thread: [Matplotlib-users] Simple gradient

Hello everyone,
I wish a simple sample of creating a pie graph filled with a gradient from
blue(#98D0D8) to a lighter blue(#BAE5EB).
Here's the code (I got from the samples):
from pylab import *
# make a square figure and axes
figure(1, figsize=(6,6))
ax = axes([0.1, 0.1, 0.8, 0.8])
labels = 'Frogs', 'Hogs', 'Dogs', 'Logs'
fracs = [15,30,45, 10]
explode=(0, 0.05, 0, 0)
pie(fracs, explode=explode, labels=labels, autopct='%1.1f%%', shadow=True)
title('Raining Hogs and Dogs', bbox={'facecolor':'0.8', 'pad':5})
show()
Thanks.

Unfortunately, there is no simple way, as MPL does not support gradient yet.
There is a hard way though, that you create a gradient image by
yourself and clip it with the appropriate path.
I guess, the easiest way for a normal user is to export the figure as
the SVG format and put some gradient using inkscape, or similar tools.
Regards,
-JJ

Ok, but there's a class called map color, I think it goes that way. But I
didn't find a way to create map colors with hexadecimal values, only with r,
g, b dicts from 0 to 1.0. I didn't get it.
I also didn't find how to apply this map colors to a pie patch.
