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()
