python - 如何使用 matplotlib 对 2D numpy 数组进行动画处理？

Question

我正在尝试使用 matplotlib 对 numpy 数组进行动画处理:

import numpy as np

import matplotlib.pyplot as plt
import matplotlib.animation as animation

arr = []
for i in range(100):
    c = np.random.rand(10, 10)        
    arr.append(c)

plt.imshow(arr[45])

我不明白应该如何为这样的数组设置动画: https://matplotlib.org/examples/animation/dynamic_image.html

哦，谢谢，这比我想象的要容易。

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

fig = plt.figure()
i=0
im = plt.imshow(arr[0], animated=True)
def updatefig(*args):
    global i
    if (i<99):
        i += 1
    else:
        i=0
    im.set_array(arr[i])
    return im,
ani = animation.FuncAnimation(fig, updatefig,  blit=True)
plt.show()
