Matplotlib: Add title to collection of plots

Use matplotlib.pyplot.suptitle() to add a centered title to the figure:

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

data = pd.DataFrame(np.random.randn(500).reshape(100,5), columns=list('abcde'))
axes = data.hist(sharey=True, sharex=True)
plt.suptitle("This is Figure title")
