Single Chart Series with multiple color data points

Question

I am developing an application using the flex chart component
and I am binding data to 3 different chart series which is pretty
intense processing. I was wondering can I use only one chart series
and when I bind the data points just to change the color per data
point which meet certain criteria?
Here one method from my application where I am dynamically
binding data to my series.
private function loadSeries(data:XMLList, yAxis:String):void
seriesAdd.yField = yAxis;
seriesAdd.xField = "Date";
//seriesDelete.yField = yAxis;
//seriesDelete.xField = "Date";
//seriesChange.yField = yAxis;
//seriesChange.xField = "Date";
seriesAdd.dataProvider = data.Trade.(A == 'Add');
seriesAdd.//Can I change the color per each data point if I
have multiple data sets?
//seriesDelete.dataProvider = data.Trade.(A == 'Delete');
//seriesChange.dataProvider = data.Trade.(A == 'Change');
Thank you

I think I found something to get me started:

My next question is if I have the following function to fill
my data points:\
private function myFillFunction(element:ChartItem,
index:Number):IFill {
var c:SolidColor = new SolidColor(0x00CC00);
var item:ColumnSeriesItem = ColumnSeriesItem(element);
var sales:Number = Number(item.yValue);
if (sales >= 50000) {
return c;
} else {
// They have not met their goal.
c.color = 0xFF0000;
return c;
How can I access values that pertain to the specific chart
item, but are not plotted on the x and y axis. Something similar to
the checking on the above function, but check if value that is not
plotted but still exists on the data provider.
Thanks in advance.
