Animation using Matplotlib with subplots and ArtistAnimation

To animate using Matplotlib with subplots and ArtistAnimation, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Create a figure and a set of subplots.
Create a user-defined function, Init, to draw a clear frame.
Use FuncAnimation to make an animation by repeatedly calling a function *func*.
Define an animate function to update the data points in FuncArtist class.
To display the figure, use show() method.

Example

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
fig, ax = plt.subplots()
xdata, ydata = [], []
ln, = plt.plot([], [], 'r*')

def init():
   ax.set_xlim(0, 100)
   ax.set_ylim(-1, 1)
   return ln,
def animate(frame):
   xdata.append(frame)
   ydata.append(np.sin(frame))
   ln.set_data(xdata, ydata)
   return ln,

ani = FuncAnimation(fig, animate, init_func=init, blit=True, frames=100)
plt.show()
