Matplotlib - Force plot display and then return to main code

Question

This is a MWE of what I\'m after, adapted from this question:

from matplotlib.pyplot import plot, draw, show

def make_plot():
    plot([1,2,3])
    draw()
          


        

Answer 1

None of the presented solutions work for me. I tested them with three different IDEs PyCharm, Spyder and Pyzo, using the (currently) latest Matplotlib 2.1 under Python 3.6.

What works for me, although not optimal, is to use a plt.pause command:

import matplotlib.pyplot as plt

def make_plot():
    plt.plot([1, 2, 3])
#    plt.show(block=False)  # The plot does not appear.
#    plt.draw()             # The plot does not appear.
    plt.pause(0.1)          # The plot properly appears.
    print('continue computation')

print('Do something before plotting.')
# Now display plot in a window
make_plot()

answer = input('Back to main and window visible? ')
if answer == 'y':
    print('Excellent')
else:
    print('Nope')
