Updating the X-axis values using Matplotlib animation

To update the X-axis values using Matplotlib animation, 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 x and y data points using numpy.
• Plot x and y data points using plot method on axis (ax).
• Make an animation by repeatedly calling a function animate that sets the X-axis value as per the frame.
• To display the figure, use show() method.

Example

import matplotlib.pylab as plt import matplotlib.animation as animation import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True fig, ax = plt.subplots() x = np.linspace(0, 15, 100) y = np.sin(x) ax.plot(x, y, lw=7) def animate(frame): ax.set_xlim(left=0, right=frame) ani = animation.FuncAnimation(fig, animate, frames=10) plt.show()
