Flex Examples

In a previous example, “Animating data changes in a Flex Pie Chart”, we looked at using the SeriesInterpolate effect to animate a pie chart when the data changed.

The following example shows how you can use the SeriesInterpolate, SeriesSlide, and SeriesZoom effects to create different animations.

Full code after the jump.
