Flex Examples

The following example shows how you can remove the default drop shadow from a Flex PieChart control by setting the filters property to an empty array in the PieSeries tag, as seen in the following snippet:

<mx:PieChart id="pieChart"
        dataProvider="{dp.product}"
        height="250"
        width="100%">
    <mx:series>
        <mx:PieSeries id="pieSeries"
                field="@data"
                filters="[]" />
    </mx:series>
</mx:PieChart>

Full code after the jump.
