I'm working with a hot new open-source Flash data visualization library (http://www.axiis.org) It doesn't (yet) have a series interpolation effect, like the Adobe Flash Charting library does.
Can anyone point me at anything that would help me understand how to do it? I gather it involves applying a tween effect between the old-data sprite and the new-data sprite.
Since I've never done any data vis graphics work, I suspect that it may well be beyond me to implement -- but I'd rather not give up before at least looking into what's involved.
