[Tkinter] updating tkinter chart from within function

[deanhystad]

How many dots do you expect to see on the scatter plot when this program is run? 2 or 102?

import matplotlib.pyplot as plt
from random import randint

x = [5, 10]
y = [5, 10]
plt.scatter(x, y)
for i in range(100):
    x.append(randint(0,100))
    y.append(randint(0,100))
plt.show()
