To redraw an image using python's Matplotlib, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Create a new figure or activate an existing figure.
Get the current axis using gca() method.
Show the current figure.
Iterate in the range of 20 and redraw the plot.
Use plot() method to plot random data points.
Redraw on the figure and pause for a while.
Close a figure window.

Example

import numpy as np
from matplotlib import pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

fig = plt.figure()
ax = fig.gca()
fig.show()

for i in range(20):
   ax.plot(np.random.randint(1, 5), np.random.randint(1, 5), '*', ms=10)
   fig.canvas.draw()
   plt.pause(0.1)

plt.close(fig)
