I was a happy matplotlib user. Unfortunately, recently it stopped working.

Starting ipython3 and executing the following commands

%matplotlib
import numpy as np
import matplotlib.pyplot as plt
t = np.r_[0:5]
plt.plot(t, t)

now produces an empty, gray window. This was working fine in a
previous version using python3.3.
