How can I capture video from a plotting function?

I am running a multi objective genetic algorithm using the command:

[vals,fvals]=gamultiobj(@MultiObj,4,[],[],[],[],lb,ub,Options)

where @MultiObj is my function, using 4 variables, lb=lower bound, ub=upper bound, and Options are specified as:

Options=gaoptimset('PlotFcns',@gaplotpareto);

This works great and produces a nice plot that updates with each generation, for my problem this is around 50 times. Is there any way to record this plot as it updates? I have no idea what is going on inside gaplotpareto. I was thinking F = getframe(h) might work, but I don't know how to update the frame or get the handle.

Thank you in advance for your help!
