[flexcoders] How can I format the text in my custom labelFunction?

[sailorsea21]

Hi everyone, 

how can I format the text in my custom labelFunction (bold, center, color...)

CategoryAxis: labelFunction="test_labelFunc".

private function 
test_labelFunc(item:String,previousItem:Object,axis:CategoryAxis,labelItem:XML):String
{
var labelArray:Array = item.split('?');
return labelArray[0] + '\n' + labelArray[1] + '\n' + labelArray[2];
}

I would like my return text to be centered and my "labelArray[0]" to be bold.

Are there any tutorials?

Thanks.
