I have a Cartesian chart containing two ColumnSeries in two ColumnSets,
like this:
<mx:series>
<mx:ColumnSet columnWidthRatio=".375" offset="-.21"
type="stacked">
<mx:ColumnSeries alpha=".6" yField="costs" />
<mx:ColumnSeries alpha=".6" yField="oneTime"/>
</mx:ColumnSet>
<mx:ColumnSet columnWidthRatio=".375" offset="0.21"
type="stacked">
<mx:ColumnSeries yField="revenue" />
<mx:ColumnSeries yField="overhead" />
</mx:ColumnSet>
</mx:series>
My problem is that data interpolation doesn't seem to work in this context.
I set up an interpolation like this:
<mx:SeriesInterpolate id="moveData"
duration="500"
minimumElementDuration="200"
elementOffset="0"/>
But when I try to call it either from the individual ColumnSeries or the
ColumnSets, using:
showDataEffect="moveData"
I get an error message: "Cannot access a property or method of a null
object reference."
Can anyone spot the problem - or is this not possible in this setup?
