I've been searching the web for a way to make given slices in a pie chart resizable via dragging a handle on the slices. Can someone help me with how to realize this in Flash, or preferably, point me at the appropriate tutorials to learn what to do to make the chart and then add resizable slices? I haven't used Flash in a long time, and I admit that AS3 is a bit overwhelming. If anyone thinks this interaction could be done better with some other tool I'm happy to hear those suggestions too!
Thanks in advance for your help.
