[Matplotlib-users] animate marker moving across plot

[Michael M. <mic...@gm...>]

 I want to plot audio data (samples versus time), and then animate a marker
moving across the plot while the audio is played back. The marker should
stay in sync with the audio data that is being played at that moment. Is
there a way to do this using the animation capabilities of matplotlib? If I
could sync the movement of the market with an accurate timer (like a QTimer
in Qt) it should be good enough.
