To use multiple font sizes in one label in Python, we can use fontsize in title() method.
Steps
Set the figure size and adjust the padding between and around the subplots.
Create x and y data points using numpy.
Plot x and y using plot() method.
Initialize a variable, fontsize.
Set the title of the plot using title() method with fontsize in the argument.
Turn off the axes.
To display the figure, use show() method.
Example
import numpy as np
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.linspace(-5, 5, 100)
y = np.cos(x)
plt.plot(x, y)
fontsize = 20
plt.title("$\\bf{y=cos(x)}$", fontsize=fontsize)
plt.axis('off')
plt.show()Output
