How to display only a left and bottom box border in Matplotlib?

Matplotlib Server Side Programming Programming

To display or hide box border in matplotlib, we can use spines (value could be right, left, top or bottom) and set_visible() method to set the visibility to True or False.

Steps

Create x and y data points using numpy.
Create a figure and add a set of subplots using subplots() method.
Plot x and y data points using plot() method, where linewidth=7 and color=red.
Set visibility as True for left and bottom, and False for top and right.
To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.linspace(-2, 2, 10)
y = np.sin(x)
fg, ax = plt.subplots()
ax.plot(x, y, lw=7, c='red')
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)
ax.spines['left'].set_visible(True)
ax.spines['bottom'].set_visible(True)
plt.show()
