Access to needed info for a ChartItem custom renderer

Question

I essentially am mimicking some code in the help files, an
example for using a 3-color repeating scheme with a ColumnChart. In
my case, however, I want to custom-color some circles in a
PlotChart.
I don't need a repeeating scheme, though. I need to be able
to choose the color based on information about the data itself. The
data originates from an HTTPService, and so each item is on Object.
Thus, I attempted to dynamically assign a property to the Object in
my app code, and then access that property within my programmatic
skin (which extends ProgrammaticSkin and implements IDataRenderer).
Does anyone know how to get information from within such a
programmatic skin?
The easy workaround here was to use three different series
and put data into the appropriate series, but this won't have the
desired visual effect with a ColumnChart, which I must also
implement.

Answer 1

Found it. You get access back to the object with
PlotSeriesItem.item -- the item property.
