How to give Matplolib imshow plot colorbars a label?
To give matplotlib imshow() plot colorbars a label, we can take the following steps −
Set the figure size and adjust the padding between and around the subplots.
Create 5×5 data points using Numpy.
Use imshow() method to display the data as an image, i.e., on a 2D regular raster.
Create a colorbar for a ScalarMappable instance, im.
Set colorbar label using set_label() method.
To display the figure, use show() method.

import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
