如何更新动画 matplotlib 图中的刻度标签

Question

How can I get the tick labels to update once changed in an animated graph? Here is just a simple example of what I need. I realize I can set blit=False and have it work, however the project I am working on requires blit=True for performance reasons.

import matplotlib
matplotlib.use('Qt4Agg')
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.animation as animation
import time

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))

    if i > 30:
        ax.tick_params(axis='y', colors='red')  ### How do I get my graph to reflect this change?
    return line,


def init():
    line.set_ydata(np.ma.array(x, mask=True))
    return line,

ani = animation.FuncAnimation(fig, animate, np.arange(1, 200), init_func=init,
                          interval=100, blit=True)
plt.show()

I got it working with the monkey patch suggested in this post.

Hope this works for wandering souls (like me) that spent A LOT of time trying to solve this problem.
