Grapher: How do I animate a parameter?

How do you animate a parameter in the OSX Grapher utility?

There is an example called "Variable Parameter" that has a time line where T varies from 0 to 10. When you move the slider, the graphs are redrawn accordingly.

I'd like to do something similar, with different equations. But I can't seem to animate any parameters. I can create a system of equations with discrete steps (using curly brace notation) or do a parametric equation that varies continuously, but none allow me to animate a parameter.

Simple example:
I'd like to create an animation for y=sin(x+t) or even y=t*sin(x). How do I do that?

Pull down the Examples menu and select "Variable Parameter". This may help you get started.

Create two equations:

t=4 (or some other random number)

Select the "t=4" equation, and select Equation > Animate Parameter
