Funcanimation Printing First Image Only

I'm trying to animate a 3D array in python using the first dimension as time. I'm not sure where I am going wrong, as I recieve no error with this code. But my animation is station

Solution 1:

The main difference between your code and any example you find on matplotlib animations is that you do not actually store the FuncAnimation. Depending on how you run things it would then directly be garbage-collected.

ani = FuncAnimation(...)
