pyplot catch windows 10 close windows event

问题

how can I catch a close event from the windows close button in pyplot? the app is totally simple, but I want to stop plotting when the windows closer is clicked.

plt.axis([0, 100, 0, 255, -5, 5])
plt.ion()
plt.show()

mainloop:
   plt.plot (whatever)
