Just point the
<mx:HTTPService id="srv"

Open in new window

to the xml file?

or

Do I need to implement E4X?




Example from Flex4 Adobe site:

<s:Application 
	xmlns:fx="http://ns.adobe.com/mxml/2009" 
	xmlns:mx="library://ns.adobe.com/flex/mx" 
	xmlns:s="library://ns.adobe.com/flex/spark" 
	creationComplete="initApp();srv.send();"
	height="600">
	
	<fx:Declarations>
		<!-- View source of the following page to see the structure of the data that Flex uses in this example. -->
		<mx:HTTPService id="srv" url="http://aspexamples.adobe.com/chart_examples/networth-xml.aspx"/>
		<!-- To see data in an HTML table, go to http://aspexamples.adobe.com/chart_examples/networth.aspx -->  
	</fx:Declarations>
	
	<fx:Script><![CDATA[
		public var initSeriesArray:Array = new Array();
		public var level:Number = 1;
		public var newSeries:Array;
		
		private function initApp():void {
			// Get initial series Array -- to be reloaded when it returns 
			// from a drill down.
			initSeriesArray = chart.series;             
		}
		
		private function zoomIntoSeries(e:Event):void {
			newSeries = new Array();
			if (level == 1) {
				newSeries.push(e.currentTarget);   
				level = 2; 
			} else {
				newSeries = initSeriesArray;
				p1.title = "Net Worth";
				level = 1;
			}           
			chart.series = newSeries;            
		}
		
	]]></fx:Script>
	
	<s:layout>
		<s:VerticalLayout/>
	</s:layout>
	
	<s:Panel id="p1" title="Net Worth">
		<s:layout>
			<s:VerticalLayout/>
		</s:layout>
		<mx:ColumnChart id="chart" 
						dataProvider="{srv.lastResult.data.result}" 
						type="stacked" 
						showDataTips="true">
			<mx:series> 
				<mx:ColumnSeries id="s1" 
								 displayName="Cash" 
								 yField="cash" 
								 xField="date" 
								 click="zoomIntoSeries(event)"/>
				<mx:ColumnSeries id="s2"

				<mx:ColumnSeries id="s5"

								 yField="other" 
								 xField="date" 
								 click="zoomIntoSeries(event)"/>
			</mx:series>            
			<mx:horizontalAxis >
				<mx:DateTimeAxis title="Date" dataUnits="months"/>
			</mx:horizontalAxis>    
		</mx:ColumnChart> 
		<mx:Legend dataProvider="{chart}"/>
	</s:Panel>
</s:Application>

Use Bindable XMLList as dataprovider, hence e4X will be required. Try this:
//XML List for loaded XML file. Must be bindable!
[Bindable]
private var chartInfo:XMLList;

private function xmlHandler(evt:ResultEvent):void{
    //Sets chartInfo's root as data. Everything else referenced in respect to this.
    chartInfo = evt.result;
}

Open in new window


In the Chart use this chartInfo variable:
 
<mx:ColumnChart id="chart" dataProvider="{chartInfo}" type="stacked" showDataTips="true">

Open in new window



Warm Regards
