Hi Ben. I believe this is a known bug with stacked charts in the 2.0 release and interpolation effects. We hope to have a fix out at some point. Sorry about the trouble.
 
Ely.

Subject: [flexcoders] Problems interpolating a BarChart

I have a BarChart that is displaying its data correctly. I also have a
combobox that, upon its change event, calls a function that
repopulates the BarChart's dataProvider. The BarChart updates its
display as expected, but if I try to set the showDataEffect attribute
of any of the child BarSeries components (which I am successfully
using on a ColumnChart elsewhere), I get an RTE with the infamous
"Error #1009: Cannot access a property or method of a null object
reference." message. The debugger opens and selects a
mx.charts.chartClasses.CartesianTransform instance, but other than
that I get no feedback on what the actual problem is. At first I
thought that maybe it was having trouble scaling some of the BarSeries
items to a value of 0, but the more I investigate, the less it seems
like that is the issue.

So my question is a basic one: does anyone have any ideas what could
be causing this or suggestions of where I should further investigate?

Thanks,
Ben
