(partially...) I was able to filter through e4x via mx:XML and the dataProvider as follows...
<mx:XML id="data" source="sep.xml" format="e4x"/>
<mx:PieChart width="100%" height="100%" dataProvider="{data.Location.(region ==
'Asia' )}">
How can I add an additional filter argument from here? Using the && technique
gave me error that "entity name must immediately follow &"
I want to filter something like: region = Asia AND GDP/capita = 10000
Thanks!
