Flex Examples

The following example shows how you can create transparent wedges in a Flex PieChart control by setting the SolidColor object’s alpha property to 0, as seen in the following snippet:

<mx:PieChart dataProvider="{arrColl}" height="100%" width="100%">
    <mx:series>
        <mx:PieSeries id="pieSeries" field="data">
            <mx:fills>
                <mx:SolidColor alpha="0.0" />
                <mx:SolidColor color="haloBlue" alpha="1.0" />
            </mx:fills>
            <mx:filters>
                <mx:Array />
            </mx:filters>
        </mx:PieSeries>
    </mx:series>
</mx:PieChart>
