Matplotlib animation either freezes after a few frames or just doesn't work

Question

I\'ve been trying for hours to get this simple script working, but nothing I do seems to help. It\'s a slight modification of the most basic animated plot sample code from t

Answer 1

When you say freezes after the first couple of frames do you mean 2 or 3, or say, 40 or 60, as those are the upper limits of your loop?

If you want the animation to continue indefinitely you need something like

while True:
    d = randn(10)
    line.set_ydata(d)
    draw()
    time.sleep(10e-3)

But you'll have to force quit your program.
