Stacked Column Chart Data Labels Not Appearing

Question

I am using SetSytle in Actionscript to make the data labels in a stacked column chart appear inside but it's not working.
A portion of the code I am using to create the chart is below:
                //initialize column set for stacked columns
                var colSet:ColumnSet = new ColumnSet();
                colSet.type="stacked";
                 for each(var node:XML in _chartDP){
                     var k:int = 0;
                     //skip zero datapoints
                     if (parseInt(node.toString()) != 0) {
                         //if measure node does not exist, add as series
                         k = uniqueYCat(node.attribute("BillTo"));
                         if (k == -1){                                                        
                                // Create the new column series and set its properties.
                                var localSeries:ColumnSeries = new ColumnSeries();
                                localSeries.setStyle("labelPosition","inside");
                                localSeries.dataProvider = dataArray;
                                localSeries.yField = node.attribute("BillTo");
                                localSeries.xField = "ConfidenceStatus";
                                localSeries.displayName = node.attribute("BillTo");
                                localSeries.setStyle("showDataEffect", ChangeEffect);
                                // Back up the current series on the chart.
                                var currentSeries:Array = chart.series;
                                // Add the new series to the current Array of series.
                                currentSeries.push(localSeries);
                                //Add Array of series to columnset
                                colSet.series.push(localSeries); 
                                   //assign columnset to chart
                                chart.series = [colSet];
After some more research, I put a breakpoint inside ColumnChart.as in the following function:
    mx_internal function getSeriesLabelPos(series:Series):void
        if(series is ColumnSeries)
            var columnSeries:ColumnSeries = ColumnSeries(series);
            var position:String = columnSeries.labelPos;
            if(position == "inside" || position == "outside" || position == "none")
                _needLabels = true;
        else if(series is ColumnSet)
            var setSeries:Array /* of Series */ = ColumnSet(series).series;
            for (var i:int = 0; i < setSeries.length; i++)
                getSeriesLabelPos(setSeries[i]);
the following line: var position:String = columnSeries.labelPos;
returns postion as null. It looks like the setStyle is not passing the correct value to this function.
Any ideas as to what is going on?

Answer 1

chart appearance is controlled by xml files located in
{cfroot}\charting\styles. the file for bar charts is
default.xml
you will want to:
1) copy thisfile to your site's root or some other folder
(i.e. same
folder that the page displaying your chart is in)
2) edit the file and change isHideOverlapped attribute of
labelStyle
property for xAxis to "false"
3) point the STYLE attribute of your cfchart tag to this new
file.
