</mx:Application>
<?xml version="1.0" encoding="utf-8"?>
<mx:Module
   xmlns:mx="http://www.adobe.com/2006/mxml"
   layout="absolute"
   percentWidth="100" percentHeight="100">
    <mx:ColumnChart id="columnchart1">
    <mx:series>
        <mx:ColumnSeries displayName="Series 1" yField="" dataProvider="{ [1, 2, 5, 8, 3] }" />
    </mx:series>
</mx:ColumnChart>`</mx:Module>`

Try this:

<mx:ModuleLoader url="TestModule.swf" width="100%" height="100%">

I would surround the Mode with something like a VBOX or a Group which also has 100%, 100% then it works fine for me.
