未在Pycharm中显示的Matplotlib动画

这段代码起了作用:

"""
A simple example of an animated plot
"""


    import matplotlib; matplotlib.use("TkAgg")
    import numpy as np
    import matplotlib.pyplot as plt
    import matplotlib.animation as animation


    fig, ax = plt.subplots()

    x = np.arange(0, 2*np.pi, 0.01)
    line, = ax.plot(x, np.sin(x))


    def animate(i):
        line.set_ydata(np.sin(x + i/10.0))  # update the data
        return line,


    # Init only required for blitting to give a clean slate.
    def init():
        line.set_ydata(np.ma.array(x, mask=True))
        return line,

    ani = animation.FuncAnimation(fig, animate, np.arange(1, 20000), init_func=init,
                                  interval=25, blit=True)
    plt.show()

注释添加 import matplotlib; matplotlib.use("TkAgg")

此外,这个问题/答案也有一定帮助: Matplotlib animations do not work in PyCharm
