Time for Action – using matplotlib in Pygame

In this recipe, we take the position coordinates of the previous section and make a graph of them.

1. To integrate matplotlib with Pygame, we need to use a non-interactive backend; otherwise matplotlib will present us with a GUI window by default. We will import the main matplotlib module and call the use() function. Call this function immediately after importing the main matplotlib module and before importing other matplotlib modules:
