How To Share Axes After Adding Subplots Via Add_subplot?

I have a dataframe like this: df = pd.DataFrame({'A': [0.3, 0.2, 0.5, 0.2], 'B': [0.1, 0.0, 0.3, 0.1], 'C': [0.2, 0.5, 0.0, 0.7], 'D': [0.6, 0.3, 0.4, 0.6]}, index=list('abcd'))

Solution 1:

The question how to produce shared subplots in matplotlib:

• The SO seach engine results
• The matplotlib recipes or the examples page

What may be more interesting here, is that you could also directly use pandas to create the plot in a single line:

import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame({'A': [0.3, 0.2, 0.5, 0.2], 'B': [0.1, 0.0, 0.3, 0.1], 'C': [0.2, 0.5, 0.0, 0.7], 'D': [0.6, 0.3, 0.4, 0.6]}, index=list('abcd'))
df.plot(kind="bar", subplots=True, layout=(2,2), sharey=True, sharex=True)
plt.show()
