Animated Plot With Subplots In Matplotlib

I've been facing some issues trying to animate a plot with several different subplots in it. Here's a MWE: import numpy as np import matplotlib.pyplot as plt import matplotlib.anim

Solution 1:

You would want to update the lines instead of plotting new data to them. This would also allow to set blit=False, because saving the animation, no blitting is used anyways.

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

data=np.random.rand(4, 50, 150)
Z=np.arange(0,120,.8)

fig, axes = plt.subplots(2,2)

lines=[]

for nd, ax in enumerate(axes.flatten()):
    l, = ax.plot(data[nd,0], Z)
    lines.append(l)

def run(it):
    print(it)
    for nd, line in enumerate(lines):
        line.set_data(data[nd, it], Z)
    return lines


ani=animation.FuncAnimation(fig, run, frames=np.arange(0,data.shape[1]), 
                            interval=30, blit=True)
ani.save('mwe.mp4')

plt.show()
