add title to collection of pandas hist plots

Question

I\'m looking for advice on how to show a title at the top of a collection of histogram plots that have been generated by a pandas df.hist() command. For instance, in the his

Answer 1

With newer Pandas versions, if someone is interested, here a slightly different solution with Pandas only:

ax = data.plot(kind='hist',subplots=True,sharex=True,sharey=True,title='My title')

Answer 2

for matplotlib.pyplot, you can use:

import matplotlib.pyplot as plt
# ...
plt.suptitle("your title")

or if you're using a Figure object directly,

import matplotlib.pyplot as plt
fig, axs = plt.subplots(...)
# ...
fig.suptitle("your title")

See this example.

Answer 3

You can use suptitle():

import pylab as pl
from pandas import *
data = DataFrame(np.random.randn(500).reshape(100,5), columns=list('abcde'))
axes = data.hist(sharey=True, sharex=True)
pl.suptitle("This is Figure title")

Answer 4

I found a better way:

plt.subplot(2,3,1)  # if use subplot
df = pd.read_csv('documents',low_memory=False)
df['column'].hist()
plt.title('your title')

It is very easy, display well at the top, and will not mess up your subplot.
