Question: Modelling pendulums in maple

I'm trying to model a simple pendulum. I have arrived at this code which gives me an animation of a point swinging.

 

 

To analyse the pendulum I want to plot a graph of phi against time, but do not know how to take readings from my animation to plot a graph with.

Thanks.
