How to animate the pie charts developed using core-plot library?

Question

In the iPhone application Roambi, the pie chart shown can be animated to rotate with the user as if rotating a disc. We can hold and do lot of stuff with that.

I didn't know CorePlot, and it might be some use for me in the near future, so I just gave it a look. CorePlot is interesting and is active.

Concerning Animations with CorePlot:

1. CorePlot documentation mentions an Animation system, but it is not implemented yet...
2. Even if based on Core Animation, it doesnt mean CorePlot graph will be easily animatable.

Interesting reading on the topic on google groups.

So here are your options (by my order of preference):

1. Look for another plotting library handling animations like Roambi does.
2. Implement your animations based on CorePlot (means a good understanding of this framework and Core Animation)
3. Do everything yourself, depending on what you want, again, might be not that hard... But Core Animation skills needed, again.

I doubt Roambi uses CorePlot, but if they do, they use it as a base with TONS of custom in house code...
