Python/Matplotlib - Change the relative size of a subplot

Question

I have two plots

import matplotlib.pyplot as plt
plt.subplot(121)
plt.subplot(122)

I want plt.subplot(122) to be half as wide

Answer 1

By simply specifying the geometry with “122”, you're implicitly getting the automatic, equal-sized columns-and-rows layout.

To customise the layout grid, you need to get a little more specific. See “Customizing Location of Subplot Using GridSpec” in the Matplotlib docs.
