Matplotlib python show() returns immediately

Question

I have a simple python script which plots some graphs in the same figure. All graphs are created by the draw() and in the end I call the show() function to block.

Answer 1

I had the same problem with this code below.

import matplotlib.pyplot as plt

plt.ion()
fig,ax0 = plt.subplots(figsize=(5.3,4))

plt.show()

I removed plt.ion(), and the plot stays without closing automatically.
