How to make axes transparent in Matplotlib?

To make axes transparent in 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 using figure() method.
Add an '~.axes.Axes' to the figure as part of a subplot arrangement.
Set face color of the current axes.
Add an axes to the figure.
Create t and s data using numpy.
Plot t and s data points using plot() method on axis 2 (from step 5).
To make the axis transparent, use set_alpha() method and keep alpha value minimum.
To display the figure, use show() method.

Example

import matplotlib.pyplot as plt
import numpy as np

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

fig = plt.figure()

ax1 = fig.add_subplot(1, 1, 1)
ax1.set_facecolor('orange')
ax2 = fig.add_axes([0.5, 0.5, 0.3, 0.3])

t = np.arange(0, 1, 0.01)
s = np.sin(t)

ax2.plot(t, s, linewidth=2)
ax2.patch.set_alpha(0.01)

plt.show()
