How to plot an animated image matrix in matplotlib?

To plot an animated image matrix in matplotlib, we can take the following steps

Steps

Set the figure size and adjust the padding between and around the subplots.
Create a figure and a set of subplots.
Make an animation by repeatedly calling a function *update*.
Inside the update method, create a 6×6 dimension of matrix and display the data as an image, i.e., on a 2D regular raster.
Turn off the axes using set_axis_off().
To display the figure, use Show() method.

Example

from matplotlib.animation import FuncAnimation
import matplotlib.pyplot as plt
import numpy as np

plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True

fig, ax = plt.subplots()

def update(i):
    im_normed = np.random.rand(6, 6)
    ax.imshow(im_normed)
    ax.set_axis_off()

anim = FuncAnimation(fig, update, frames=20, interval=50)

plt.show()

Output

It will produce the following output −
