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

Yes, and if you want to reduce your code to a single line, you can put all kwargs that are to be passed to matplotlib.gridspec.GridSpec(), into the gridspec_kw parameter of plt.subplots():

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

fig, axs = plt.subplots(nrows=2, ncols=2, gridspec_kw={'width_ratios':[2,1], 'height_ratios':[2,1]})

df = pd.DataFrame(np.random.randn(10, 3), columns=['A', 'B', 'C'])
df.plot.bar(ax=axs[0][0])
df.boxplot(ax=axs[0][1])
df.plot.line(ax=axs[1][0])
df.plot.kde(ax=axs[1][1])
