How to set the font size of Matplotlib axis Legend?

Matplotlib Server Side Programming Programming

To set the font size of matplotlib axis legend, we can take the following steps −

Create the points for x and y using numpy.
Plot x and y using the plot() method with label y=sin(x).
Title the plot using the title() method.
To set the fontsize, we can override rcParams legend fontsize by value 20.
Use the legend() method, and fit the legend at the top-right position.
To display the figure, use the show() method.

Example

import numpy as np
from matplotlib import pyplot as plt
import matplotlib
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.linspace(1, 10, 50)
y = np.sin(x)
plt.plot(x, y, c="red", lw=7, label="y=sin(x)")
plt.title("Sine Curve")
matplotlib.rcParams['legend.fontsize'] = 20
plt.legend(loc=1)
plt.show()
