How to fill the area under a step curve using pyplot? (Matplotlib)

To fill the area under step curve using pyplot, we can take the following steps

Steps

Set the figure size and adjust the padding between and around the subplots.
Ceate random data points, x, y1 and y2, using numpy.
To fill the area under the curve, put x and y with ste="pre", using fill_between() method.
Plot (x, y1) and (x, y2) lines using plot() method with drawstyle="steps" method.
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

x = np.linspace(-10, 10, 100)
y1 = np.sin(x)
y2 = np.cos(x
plt.fill_between(x, y1, step="pre", alpha=0.4)
plt.fill_between(x, y2, step="pre", alpha=0.4)

plt.plot(x, y1, drawstyle="steps")
plt.plot(x, y2, drawstyle="steps")

plt.show()
