Positioning labels in a Flex PieChart control
The following example shows how you can position callouts in a PieChart control’s pie series by setting the labelPosition style.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical"
verticalAlign="middle"
backgroundColor="white">
<mx:Script>
<![CDATA[
private function pieSeries_labelFunc(item:Object, field:String, index:Number, percentValue:Number):String {
return item.@label + ": " + item.@data + " (" + percentValue.toFixed(2) + "%)";
}
]]>
</mx:Script>
<mx:XML id="dp">
<products>
<product label="Product 1" data="3" />
<product label="Product 2" data="1" />
<product label="Product 3" data="4" />
<product label="Product 4" data="1" />
<product label="Product 5" data="5" />
<product label="Product 6" data="9" />
</products>
</mx:XML>
<mx:Array id="labelPositionArr">
<mx:Object label="callout" />
<mx:Object label="inside" />
<mx:Object label="insideWithCallout" />
<mx:Object label="none" />
<mx:Object label="outside" />
</mx:Array>
<mx:ApplicationControlBar dock="true">
<mx:Label text="labelPosition:" />
<mx:ComboBox id="comboBox"
dataProvider="{labelPositionArr}" />
</mx:ApplicationControlBar>
<mx:PieChart id="pieChart"
dataProvider="{dp.product}"
height="250"
