Skinning Data Item in Chart in Flex4:

In this section you can see how we can provide the skin to data item in chart control. We will use the itemRenderer for providing the skin to data item. In this example we change the representation of data item. we use the image for showing the data values in the chart.

Example:

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

xmlns:s="library://ns.adobe.com/flex/spark"

xmlns:mx="library://ns.adobe.com/flex/mx"

minWidth="955" minHeight="600">

<fx:Declarations>

<s:SolidColor id="s3" color="#cc00cc" alpha=".3"/>

<s:SolidColorStroke id="scs3" color="#cc00cc" weight="2"/>

</fx:Declarations>

<fx:Style>

@namespace s "library://ns.adobe.com/flex/spark";

@namespace mx "library://ns.adobe.com/flex/mx";

mx|Legend{

label-placement:right;

marker-height:30;

marker-width:30;

background-color:#000000;

}

mx|LegendItem{

font-family: verdana;

font-size:12px;

color: #FFFFFF;

font-weight:bold;

}

</fx:Style>

<fx:Script>
