How to update the plot title with Matplotlib using animation?

To update the plot title with Matplotlib using animation, 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 using figure() method.
Create x and y data points using numpy.
Get the current axis.
Add text to the axes using text() method.
Add an animate method that can be used to make an animation by repeatedly calling a function.
To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt, animation

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

fig = plt.figure()

x = np.linspace(-10, 10, 1000)
y = np.sin(x)

plt.plot(x, y)

ax = plt.gca()
ax.text(0.5, 1.100, "y=sin(x)", bbox={'facecolor': 'red',
                                       'alpha': 0.5, 'pad': 5},
         transform=ax.transAxes, ha="center")

def animate(frame):
   ax.text(0.5, 1.100, "y=sin(x), frame: %d" % frame,
            bbox={'facecolor': 'red', 'alpha': 0.5, 'pad': 5},
            transform=ax.transAxes, ha="center")

ani = animation.FuncAnimation(fig, animate, interval=100,
                              frames=10, repeat=True)

plt.show()
