Question

我是Flex的初学者，最近使用Flash Builder 4.6开始使用Flex Mobile Projects。此项目适用于 Android 。

我想在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，会产生效果。效果包括“滑动打开”效果和“轻轻拉出切片”效果。但是，Legends有一个标签，但没有颜色。

为什么会发生这种情况，而是解决方案呢？

提前感谢您提供的任何帮助..

Answer 1

删除系列插值可能会解决问题。这对我有用。

Answer 2

系列插值效果存在一些问题如果你删除效果一切正常所以请参考链接动态绘制图例 http://help.adobe.com/en_US/flex/using/WS2db454920e96a9e51e63e3d11c0bf69084-7c3e.html

图例颜色未在Flex Mobile Project中显示？
