Customizing radial strokes in a Flex PieChart control
The following example shows how you can customize the radial stroke in a Flex PieChart control by using the PieSeries class’s radialStroke
style and the mx.graphics.Stroke class, as seen in the following snippet:
<mx:PieChart dataProvider="{dp.product}" height="250" width="100%"> <mx:series> <mx:PieSeries id="pieSeries" field="@data"> <mx:radialStroke> <mx:Stroke color="black" weight="2" /> </mx:radialStroke> <mx:filters> <mx:Array /> </mx:filters> </mx:PieSeries> </mx:series> </mx:PieChart> Full code after the jump. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" verticalAlign="middle" backgroundColor="white"> <mx:Script> <![CDATA[ import mx.graphics.Stroke; private function setStroke(evt:Event):void { var stroke:Stroke = new Stroke(); stroke.color = colorPicker.selectedColor; stroke.weight = slider.value; stroke.caps = comboBox.selectedItem.label; pieSeries.setStyle("radialStroke", stroke); } ]]> </mx:Script> <mx:XML id="dp"> <products> <product label="Product 1" data="3" /> <product label="Product 2" data="1" /> <product label="Product 3" data="4" /> <product label="Product 4" data="1" /> <product label="Product 5" data="5" /> <product label="Product 6" data="9" /> </products> </mx:XML> <mx:ApplicationControlBar dock="true"> <mx:Form styleName="plain"> <mx:FormItem label="color:"> <mx:ColorPicker id="colorPicker" change="setStroke(event);" /> </mx:FormItem> <mx:FormItem label="weight:"> <mx:HSlider id="slider" minimum="0" maximum="10" value="0" liveDragging="true" snapInterval="1" tickInterval="1" change="setStroke(event);" /> </mx:FormItem> <mx:FormItem label="caps:"> <mx:ComboBox id="comboBox" change="setStroke(event);"> <mx:dataProvider> <mx:Array> <mx:Object label="none" /> <mx:Object label="round" /> <mx:Object label="square" /> </mx:Array> </mx:dataProvider> </mx:ComboBox> </mx:FormItem> </mx:Form> </mx:ApplicationControlBar> <mx:PieChart id="pieChart" dataProvider="{dp.product}" height="100%" width="100%"> <mx:series> <mx:PieSeries id="pieSeries" field="@data" labelPosition="callout"> <mx:radialStroke> <mx:Stroke color="black" weight="0" caps="none" /> </mx:radialStroke> <mx:filters> <mx:Array /> </mx:filters> <mx:perWedgeExplodeRadius> <mx:Array> <mx:Number>0.2</mx:Number> </mx:Array> </mx:perWedgeExplodeRadius> </mx:PieSeries> </mx:series> </mx:PieChart> </mx:Application> |
