Bug summary
matplotlib==3.6.0 started raising an error when trying to add a colorbar to plt.hist():
ValueError: Unable to determine Axes to steal space for Colorbar. Either provide the cax argument to use as the Axes for the Colorbar, provide the ax argument to steal space from it, or add mappable to an Axes.
Code for reproduction
import matplotlib.pyplot as plt
import numpy as np
xs = np.random.rand(100)
_, bin_edges, bars = plt.hist(xs)
color_map = getattr(plt.cm, "hot")
for x_val, rect in zip(bin_edges, bars.patches):
rect.set_color(color_map(x_val))
cbar = plt.colorbar(
plt.cm.ScalarMappable(cmap=color_map),
# cax=ax.inset_axes([0.95, 0.1, 0.05, 0.8]),
