Research direction

Start with the provided Jupyter example and trace plt.pause to the FigureCanvasBase.start_event_loop_default entry point mentioned in the report, using issue #17 for related context. Done means the example runs without the removed-API AttributeError and both plots can be displayed and closed as described.

Written by the indexing model from the issue text.

Description

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.
