plt.pause uses removed `start_event_loop_default` API

As the title suggests, attempting to pause through matplotlib currently raises an error. The minimum working example is:

%matplotlib widget
from matplotlib import pyplot as plt

plt.plot([1,2,3])
plt.pause(1)    
plt.plot([3,2,1])
plt.close()

This raises an attribute error trying to call FigureCanvasBase.start_event_loop_default. A little googling suggests this function has been removed since version 3.0.

Taking inspiration from #17, I guess the simplest get around is using time.sleep but is there a better solution?

Thanks for your help.

I’m not sure sleep works for me because in my case I want to pause for matplotlib event handling.

In my case I have code running in a loop that needs to periodically update the plot and get mouse events from the plot.

Is this a problem in jupyter-matplotlib or in matplotlib in general?

@Michael-Equi I think my proposed solution should work pretty well as a permanent fix. The issue is that it has remained as “proposed” and never made it all the way to implemented
