Flex column chart in actionscript

Question

The following code is based on a routine that up until recently was working. I modified it so that it would be easier to fit into a forum post.
I need to do this in actionscript because the charts are created on the fly. The following code simply gives a blank chart.  What am I doing wrong?
public function makeDummyChart(genericChart:CartesianChart, genericLegend:Legend, chartPanel:ChartPanel):void {
            var renderers:ArrayCollection = new ArrayCollection();
            genericChart = new ColumnChart();
            // Define the two axes.
            var dispAxis:CategoryAxis = new CategoryAxis();
            var axr:AxisRenderer = new AxisRenderer();             
            axr.axis = dispAxis;
            renderers.addItem(axr);
            var seriesList:ArrayCollection=new ArrayCollection();
            // Add the series
            genericChart.horizontalAxis = dispAxis;
            var columnSeries:ColumnSeries = new ColumnSeries();    
            BindingUtils.bindProperty(columnSeries, "dataProvider", this, "columnDat");
            columnSeries.xField="signalID";;
            columnSeries.yField="point2";
            seriesList.addItem(columnSeries);
            genericChart.series = seriesList.toArray();
            genericLegend.dataProvider = genericChart;
            genericChart.horizontalAxisRenderers = renderers.toArray();
            genericLegend.dataProvider = genericChart;
            // chart panel is just the panel on the screen where chart is displayed
            chartPanel.addChild(genericChart);
                trace ("  make dummy chart done");

Hi,
Try to read the SAP Note n°882897.
It explains that when "All" is assigned as an interval from All to All, it's treated as a set of all sub values.
I hope it helps.
