Problem

the blitting minimal example with pause does not work (tested on Windows and Linux), the line (ln)/ ax.plot is shown for only one frame each animation step. calss based example or minimal without pasue works fine

Suggested improvement

Add the draw_event callback from the extended example, like this:

def on_draw(event):
        """Callback to register with 'draw_event'."""
        fig.canvas.figure.draw_artist(ln)

fig.canvas.mpl_connect("draw_event", on_draw)

also add the necessity of this callback to the strategy part of the documentation
