matplotlib.pyplot.ion#

matplotlib.pyplot.ion()[source]#

Enable interactive mode.

See pyplot.isinteractive for more details.

ioff: Disable interactive mode.
isinteractive: Whether interactive mode is enabled.
show: Show all figures (and maybe block).
pause: Show all figures, and block for a time.

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 optional usage as a context manager, this function returns a context manager object, which is not intended to be stored or accessed by the user.
