@plinius_prem thanks for your help. there is other question about how to save the maximized figure by `plt.savefig` — F.grey, Aug 30 '17 at 09:08

I did have a similar problem and found solution here on SO.I think that you need plt.ion().One example

import numpy as np
from matplotlib import pyplot as plt

def main():
    plt.axis([-20,20,0,10000])
    plt.ion()
    plt.show()

    x = np.arange(-20, 21)
    for pow in range(1,5):   # plot x^1, x^2, ..., x^4
        y = [Xi**pow for Xi in x]
        plt.plot(x, y)
        plt.draw()
        plt.pause(0.001)
        input("Press [enter] to continue.")

if __name__ == '__main__':
    main()

Works fine,although it gives this warning

 MatplotlibDeprecationWarning: Using default event loop until function specific to this GUI is implemented
  warnings.warn(str, mplDeprecation)

I am not sure if that is related to 3.6 version or not.

+1 Out of several SO answers, this is the one that works for me. NB I had to add `plt.pause(0.1)` after the initial `plt.show()` to display the first figure. Other answers suggested `draw` alone, `pause` alone, `ion` alone, using `show(block=False)`... none of these worked. — Petr Vepřek, Mar 26 '20 at 15:12
