[Matplotlib-users] polar graph

[bubye <joe...@gm...>]

Hi,  i'm wondering if there is an easy way to fill the background in a polar
graph with a specific color.  If I were making a pie graph, it'd be
something like: pie([70,20,10]), where the first 70% is green, the next 20,
yellow, and the last 10, red.  I've been experimenting with polar graphs
using some random data and i've gotten close to what I want, but it'd be
neat to have a color in the background.  Here's what I have now. it's a
polar scatter plot, much like what is found in the gallery, but with a few
changes.

from pylab import *
import numpy as np

snp=[]
for i in range(0,65):
    snp.append(np.random.randint(35,122))

tempTuple=array(snp)

r = tempTuple/10
theta = ((tempTuple*2.9508)*pi)/180
area = r**2*(tempTuple/5.4)
colors = theta
ax = subplot(111, polar=True)
c = scatter(theta, r, c=colors, s=area)
c.set_alpha(0.75)
show()
