[flexcoders] How to programmatically change fill color (Flex Charting)

[Private Romeo]

I have a SolidColor fill for a ColumnSeries object:

 

<mx:ColumnSeries displayName="Staff" yField="People" id="peopleCol">

<mx:fill>

                                <mx:SolidColor id="peopleColColor"
color="{_peopleColColor}" />

                </mx:fill>

</mx:ColumnSeries>

 

In an ActionScript function I'd like to change the color of this fill,
however neither data binding seems to work, nor directly accessing the
property:

 

function changeColor()

{

  peopleColColor.color = 0xffff00; // DOES NOT WORK

 _peopleColColor = 0xffff00; // DOES NOT WORK (and is bindable)

}

 

Any hint?
