一代码
参考官网
""" ================= An animated image ================= This example demonstrates how to animate an image. """ import numpy as np 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):#args自身参数,如果有传入参数则缺省自身参数 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()
