The XML format should be as shown below.
<?xml version="1.0" encoding="utf-8" ?>
<items>
<item name="option1" number="2000" />
<item name="option2" number="9000" />
<item name="option3" number="5000" />
<item name="option4" number="7000" />
</items>
The Flex application code is shown below.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:HTTPService id="dataRequest" url="" showBusyCursor="true" fault="dataRequestFaultHandler(event);" />
<mx:Script>
<![CDATA[
import mx.rpc.events.ResultEvent;
import mx.rpc.events.FaultEvent;
import mx.controls.Alert;
import mx.collections.ArrayCollection;
public function initApp():void {
var timeStampForNocache:Date = new Date() ;
var urlAgent:String = "Your XML returing URL PATH & tim=" + timeStampForNocache.toString();
dataRequest.url = urlAgent;
dataRequest.send();
}
[Bindable]
private var stats:ArrayCollection;
private function dataRequestFaultHandler(event:FaultEvent):void {
Alert.show(event.fault.message);
}
]]> </mx:Script>
<mx:PieChart width="100%" height="100%" showDataTips="true" dataProvider="{dataRequest.lastResult.items.item}" id="myChart">
<mx:series>
<mx:PieSeries width="100%" height="100%" field="number" nameField="name" />
</mx:series>
</mx:PieChart>
<mx:Legend direction="horizontal" dataProvider="{myChart}"/>
