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:
Unfortunately this is not possible to do. (Provide Kenyote feedback to Apple if you'd like to see this feature added!) Here are two possible alternatives:
Create 2 copies of the object on the slide and have them build in/out in sequence. This will keep your slide deck cleaner and make it easier to align the objects.
(objects shown separately for illustrative purposes; you'd want to align them perfectly!)
As you suggested, create 2 copies of the slide with no transition (so the effect is seamless and there's no delay). This will make it easier to see how you've set up the effect in your list of slides. (But if nothing else on the slide changes, it might just be annoyingly redundant.)
If I understand you correctly, you want the first bullet point to exit stage left, and have its replacement arrive from stage right. Then repeat wi point three.
Create each bullet point in its own text box. You can manually mimic the build in to match the rest of your presentation. Once the slide's build is complete, the easiest animation might be with a couple of additional slides set to Magic Move.
If you're familiar with the Magic Move transition, this should make sense. If you're not accustomed to it, play and discover some fun!

Here's one approach that's fairly quick and easy:
Create a Pie chart and input its values with the Chart Data Editor.
With the chart object selected, open the Slide Inspector and set the transition for Magic Move
With the chart still selected, copy the chart object using the menu or ⌘ + c
Create a new slide following your original and paste the chart object onto it.
Use the Chart Data Editor to change the values for your pie slices to reflect the new figures.
The chart will now morph from old to new when you advance the slides.
