Flex bar chart with Two Y axis
I am trying to create a bar char in action 3 script. But for some reason I am getting 2 y-axis and no x axis.
Can some one help spot the error. I have said "placement " bottom.
The chart creation method is "getBarChartData开发者_如何学C", this method when invoked creates a barchart and adds it to a canvas.
This section is visible completely and can be called on a button click.
For some reason, the CDATA section is interfering with the preview of the snippet.
The standalone code snippet is below.
[Bindable]
 public var QUANTITY:ArrayCollection = new ArrayCollection([
   {date:"22-Aug-05", quantity:1575.9},
   {date:"23-Aug-05", quantity:1603.},
   {date:"24-Aug-05", quantity:1507.1},
   {date:"25-Aug-05", quantity:1568.8},
]);
private function getBarChartData(evt:MouseEvent):void{
 var title:String = "ASDFZXCVB";
 var pnlChart:Panel = new Panel();
 pnlChart.title = title;
 pnlChart.height = 750;
 {
  var categoryAxisDate:CategoryAxis = new CategoryAxis();
  categoryAxisDate.categoryField = "date";
  var linearVolumeAxis:LinearAxis = new LinearAxis();
  linearVolumeAxis.minimum = 1500;
  linearVolumeAxis.maximum = 1700;
  var colChart:ColumnChart = new ColumnChart();
  colChart.showDataTips = true;
  {
   var horizontalAxisDateRenderer:AxisRenderer = new AxisRenderer();
   horizontalAxisDateRenderer.axis = categoryAxisDate;
   horizontalAxisDateRenderer.placement = "bottom";
   var quantityRenderer:AxisRenderer = new AxisRenderer();
   quantityRenderer.axis = linearVolumeAxis;
   quantityRenderer.placement = "left";
   colChart.horizontalAxisRenderers.push(horizontalAxisDateRenderer);
   colChart.verticalAxisRenderers.push(quantityRenderer);
   {
    var quantityColumnSeries:ColumnSeries = new ColumnSeries();
    quantityColumnSeries.horizontalAxis = categoryAxisDate;
    quantityColumnSeries.yField="quantity";
    quantityColumnSeries.displayName ="QUANTITY";
    quantityColumnSeries.dataProvider = QUANTITY;
    quantityColumnSeries.verticalAxis = linearVolumeAxis;
    colChart.series.push(quantityColumnSeries);
   }
  }
  pnlChart.addChild(colChart);
 }
 canvasReportId.addChild(pnlChart);
}
]]>
           <mx:Button label="Submit" click="getBarChartData(event)"  x="293" y="4"/>
          </mx:Canvas>
try to add it with MXML like so:
<mx:ColumnChart id="chart" dataProvider="{QUANTITY}">
 <mx:horizontalAxis>
       <mx:CategoryAxis 
            dataProvider="{QUANTITY}" 
            categoryField="date"
        />
 </mx:horizontalAxis>
</mx:ColumnChart>
This worked for me... Ladislav
