How to plot data to the same figure for every run?

Hi,

I'm sorry that was incorrect. The following works for me:

import matplotlib.pyplot as plt

plt.ion() # This puts plt in interactive mode
plt.plot([1,2,3,4])
input("Press enter")
plt.plot([2,4,1,3])
input("Press enter")

while True: # This prevents the plot from closing
    pass
