Re: [Matplotlib-users] sector colouring?

[Joe K. <jki...@wi...>]

Have a look at fill_between:
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.fill_between

Basically, You'd want something like this:

import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, np.pi, 20)
y = np.sin(x)
plt.figure()
plt.fill_between(x, y, where=y>0, facecolor='blue', interpolate=True)
plt.fill_between(x, y, where=y<0, facecolor='yellow', interpolate=True)
plt.show()

Hope that helps!
