Hi,

I am assuming for playing video you are using vision.VideoPlayer. In that you can see the output frame-by-frame using step and readFrame. Here you can extract a plot after a particular number of steps. Also, if you are simulating a model and then getting the output you may use pause for stopping the program after a particular time instance and then can extract variable values or plotted graph.

Hope it helps.
