How to display interactive plot spyder python 3.5.2

Question

i wanted to to have 3d plot were the z values change every second and the change is displayed in the plot. And it works...kinda. Only the very last plot is actually shown. Before that the Figure just stays blank. I thought it had to do with my script. But then I used a working example from the rawspberry website with exactly the same result. Blank window, after script is done the last actually gets displayed. I can't find any working solution for this problem so far.

Here is the code of the example from the rwaspberry website:

 import matplotlib.pyplot as plt from time import sleep from random import shuffle plt.ion() y = [i for i in range(100)] x = [i for i in range(len(y))] for i in range(50): plt.clf() plt.bar(x,y) plt.draw() sleep(0.5) shuffle(y)

Use plt.pause() instead of sleep()

for i in range(50): plt.clf() plt.bar(x,y) plt.draw() plt.pause(0.5) shuffle(y)
