我是 Flex 的初学者，最近开始使用 Flash Builder 4.6 进行 Flex 移动项目。该项目适用于Android。

我想在我的饼图中添加效果并使用：

<mx:SeriesInterpolate id="interpol" 
duration="1000" 
elementOffset="0" 
minimumElementDuration="200"
/>

整个代码如下：

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx"
        creationComplete="init()"
        title="Pie Chart">


    <fx:Script>
        <![CDATA[ 
        import mx.charts.events.ChartItemEvent;
        import mx.collections.ArrayCollection;


        [Bindable]
        public var expenses:ArrayCollection = new ArrayCollection([
        { Expense:"Taxes", Amount:2000 },
        { Expense:"Rent", Amount:1000 },
        { Expense:"Timepass", Amount:500 },
        { Expense:"Screwing Around", Amount:3200 },
        { Expense:"Food", Amount:200 } ]);


        private function init():void
        {
            pieSeries1.setStyle("showDataEffect", interpol);
            myPieChart.dataProvider=expenses;
        }

        private function setLegends():void
        {
            pieLegend.dataProvider=myPieChart;
        }

        private function pieChart_itemClick(event:ChartItemEvent):void
        {
            pieHighlight( event.currentTarget.id , event.hitData.chartItem.index );
        }

        private function pieHighlight( pieName:String, pieIndex:int ):void
        {
            var explodeData:Array = [];  //create an empty array
            explodeData[ pieIndex ] = 0.15; //Set the index of our pie piece to > 0
            this[pieName].series[0].perWedgeExplodeRadius = explodeData;
            myPieChart.dataProvider=expenses;
        }

        ]]> 
    </fx:Script>

    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
        <mx:SeriesInterpolate id="interpol" 
                              duration="1000" 
                              elementOffset="0" 
                              minimumElementDuration="200"
                              />
    </fx:Declarations>

    <mx:PieChart id="myPieChart" x="49" y="93" width="100%" height="100%" itemClick="pieChart_itemClick(event);"
                   selectionMode="multiple" showDataTips="true" creationComplete="setLegends();">
        <mx:series>
            <mx:PieSeries id="pieSeries1" field="Amount" labelPosition="callout" nameField="Expense"/>
        </mx:series>
    </mx:PieChart>
    <mx:Legend id="pieLegend"/>
</s:View>

我注意到，当我动态设置 dataProvider （myPieChart.dataProvider=expenses）时，效果就会发生。效果包括“滑动打开”效果和“轻轻拉出切片”效果。但是，Legends 有标签但没有颜色。

为什么会发生这种情况，解决方案是什么？

提前感谢您提供的任何帮助..

删除系列插值可能会解决问题。这对我有用。
