How to draw axis lines inside a plot in Matplotlib?

To draw axis lines inside a plot 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.
Create x data points using numpy.
Add an 'ax' to the figure as part of a subplot arrangement.
Plot x and x**x data points using plot() method.
Set the left and bottom positions at 0, whereas color of the right and top spines none.
To display the figure, use show() method.

Example

import numpy as np
import matplotlib.pyplot as plt

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

fig = plt.figure()

x = np.linspace(-5, 5, 100)

ax = fig.add_subplot(111)
ax.plot(x, x*x)

ax.spines['left'].set_position('zero')
ax.spines['right'].set_color('none')
ax.spines['bottom'].set_position('zero')
ax.spines['top'].set_color('none')

plt.show()

Output

It will produce the following output
