import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation # Set the figure size plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True # Random data for the contour plot data = np.random.randn(800).reshape(10, 10, 8) # Create a figure and a set of subplots fig, ax = plt.subplots() # Method to change the contour data points def animate(i): ax.clear() ax.contourf(data[:, :, i], cmap='plasma') # Call animate method ani = animation.FuncAnimation(fig, animate, 5, interval=50, blit=False) # Display the plot plt.show()
