[flexcoders] chart and dataProvider

[ddanone2]

Using same sample from Adobe doc to show a chart but trying to load
data with HTTPService. Don't know why it doesn't show anything.

Please any suggestions, thanks.

This is the XML file:

<?xml version="1.0" encoding="iso-8859-1"?>
<data>
        <mes label='Enero'>
                <dia label='01/01/2006' value='200'/>
                <dia label='02/01/2006' value='300'/>
                <dia label='03/01/2006' value='400'/>
                <dia label='04/01/2006' value='500'/>
        </mes>
</data>

This is the MXML file:
