I was struggling with this same problem for quite a while. I would recommend taking a look at this example: http://matplotlib.sourceforge.net/examples/animation/strip_chart_demo.html

Turns out the only difference in my code was that the animation.FuncAnimation() was not assigned to a variable. As soon as I assigned the return value of animation.FuncAnimation() to a value, everything worked.
