Create animations from equations in Grapher on Mac
You can create animations of equations you’ve graphed.
Animate an equation in QuickTime
In the Grapher app
on your Mac, create or open a graph.
Choose Equation > Create Animation, then do any of the following:
Change settings under Animation: Enter values in the Duration, Size, Sampling, and Number of Frames fields.
Change parameter values: Use the list of options to animate a parameter by selecting its checkbox, or to enter its initial and final values. You must assign a value to the parameter in the Equations list in order to animate it—for example, T=.5.
Set magnification levels: Click Zoom, then select your settings.
Set boundaries: Click Frame Limits, then select your settings.
Set a 3D graph’s initial and final frame rotation: Click Orientation, then drag the image in the Initial and Final frames to rotate them.

In the Grapher app
on your Mac, create or open a graph.
Select a parameter definition in the Equations list, choose Equation > Animate Parameter, then do any of the following:
Change the plotted value: Enter a value in the field or drag the playhead.
Change the range of values: Click the Settings button
.
Set the animation speed and whether to loop the animation: Click the Settings button
.
Click the Play button
to view the animated equation. To stop playing it, press the Stop button
.
Click the Create Movie button
