Notes

For a temporary change, this can be used as a context manager:

# if interactive mode is off
# then figures will not be shown on creation
plt.ioff()
# This figure will not be shown immediately
fig = plt.figure()

with plt.ion():
    # interactive mode will be on
    # figures will automatically be shown
    fig2 = plt.figure()
    # ...

To enable usage as a context manager, this function returns an _IonContext object. The return value is not intended to be stored or accessed by the user.
