Animate a pie-chart in Keynote Suppose I want to compare two situations via two pie-charts. I know I can grow a pie-chart per part in an animation or on click. But I would like to be able to transition that pie-chart to new numbers and it grows or shrinks the appropriate parts automagically.

Clarification: I would like to animate between these two pie-charts:
I also wanted this effect , and am getting close to what I want by setting the first slide transition to 'Magic Move' with zero delay and Start Transition on 'Automatically', and then duplicating the first slide about 25 times, and incrementing each segment data value on each slide to get close to 'smooth clock winding' action on 'Play'
