Make Title Box Span Entire Plot in Matplotlib

To make width of title box span the entire plot in matplotlib, we can take the following 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 data points using plot() method, with color=black and linewidth=7.
• Get the current axes using gca() method.
• Set the title of of the plot.
• Return the bbox patch using get_bbox_patch() method
• 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(-2, 2, 100)
y = np.sin(x)
plt.plot(x, y, c='black', lw=7)
ax = plt.gca()
title = ax.set_title("y=sin(x)", backgroundcolor='red')
bb = title.get_bbox_patch()
plt.show()
