Constrained layout attempts to resize subplots in a figure so that there are no overlaps between axes objects and labels on the axes.

Resizing axes with constrained layout
=====================================
Constrained layout attempts to resize subplots in
a figure so that there are no overlaps between axes objects and labels
on the axes.

SyntaxError: invalid syntax
If we don't use constrained_layout, then labels overlap the axes
fig, axs = plt.subplots(nrows=2, ncols=2, constrained_layout=False)
for ax in axs.flat:
example_plot(ax)
adding constrained_layout=True
automatically adjusts.
fig, axs = plt.subplots(nrows=2, ncols=2, constrained_layout=True)
for ax in axs.flat:
example_plot(ax)
Below is a more complicated example using nested gridspecs.
fig = plt.figure(constrained_layout=True)
import matplotlib.gridspec as gridspec
gs0 = gridspec.GridSpec(1, 2, figure=fig)
gs1 = gridspec.GridSpecFromSubplotSpec(3, 1, subplot_spec=gs0[0])
for n in range(3):
ax = fig.add_subplot(gs1[n])
example_plot(ax)
gs2 = gridspec.GridSpecFromSubplotSpec(2, 1, subplot_spec=gs0[1])
for n in range(2):
ax = fig.add_subplot(gs2[n])
example_plot(ax)
plt.show()
The use of the following functions and methods is shown in this example:
import matplotlib
matplotlib.gridspec.GridSpec
matplotlib.gridspec.GridSpecFromSubplotSpec
