How can I set the background color on specific areas of a pyplot figure?

Question

I\'ve managed to plot a series of points with the following code:

plt = pp.figure()
for i in range(spt.shape[1]):
    spktrain = spt[0,i]
    for trial in sp         


        

Answer 1

You can use axhspan and/or axvspan like this:

import matplotlib.pyplot as plt

plt.figure()
plt.xlim(0, 5)
plt.ylim(0, 5)

for i in range(0, 5):
    plt.axhspan(i, i+.2, facecolor='0.2', alpha=0.5)
    plt.axvspan(i, i+.5, facecolor='b', alpha=0.5)

plt.show()
