爲了使在jupyter筆記本the example工作,你需要包括
%matplotlib notebook
魔法命令。
import numpy as np
%matplotlib notebook
import matplotlib.pyplot as plt
import matplotlib.animation as animation
fig = plt.figure()
def f(x, y):
return np.sin(x) + np.cos(y)
x = np.linspace(0, 2 * np.pi, 120)
y = np.linspace(0, 2 * np.pi, 100).reshape(-1, 1)
im = plt.imshow(f(x, y), animated=True)
def updatefig(*args):
global x, y
x += np.pi/15.
y += np.pi/20.
im.set_array(f(x, y))
return im,
ani = animation.FuncAnimation(fig, updatefig, interval=50, blit=True)
plt.show()
然後,您可以很容易地將它調整到您的圖像列表。
從matplotlib 2.1版本開始,您也可以選擇內嵌創建JavaScript動畫。

完整的示例:
import numpy as np
%matplotlib inline
import matplotlib.pyplot as plt
import matplotlib.animation as animation
def f(x, y):
return np.sin(x) + np.cos(y)
x = np.linspace(0, 2 * np.pi, 120)
y = np.linspace(0, 2 * np.pi, 100).reshape(-1, 1)
im = plt.imshow(f(x, y), animated=True);
def updatefig(*args):
global x, y
x += np.pi/15.
y += np.pi/20.
im.set_array(f(x, y))
return im,
ani = animation.FuncAnimation(fig, updatefig, interval=50, blit=True)
