[flexcoders] sailorsea21 - How can I add the "%" symbol on my vertical axis in my chart?

[sailorsea21]

Hello everyone, 
How can I add the "%" symbol on my vertical axis after my value?

<mx:LinearAxis id="percent" interval="10"/>
<mx:LineSeries verticalAxis="{percent}" yField="test"  
showDataEffect="interpolate"/>

Thanks
