I came across this example in the Matplotlib website. I was wondering if it was possible to increase the figure size.

I tried with


but it does nothing.

If you already have the figure object use:


But if you use the .subplots() command (as in the examples you’re showing) to create a new figure you can also use:

f, axs = plt.subplots(2,2,figsize=(15,15))

Alternatively, create a figure() object using the figsize argument and then use add_subplot to add your subplots. E.g.

import matplotlib.pyplot as plt
import numpy as np

f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')

Simple Example

Benefits of this method are that the syntax is closer to calls of subplot() instead of subplots(). E.g. subplots doesn’t seem to support using a GridSpec for controlling the spacing of the subplots, but both subplot() and add_subplot() do.
