1、设计思路 （1）设计一个组合图，该图共用一个数据源 （2）组合图是有柱状图和折线图组合的 （3）柱状图显示的数据是依据左边的竖直轴，折线图的数据依据右边的竖直轴 2、源码如下 DoubleY.mxml： 复制代码 代码如下: <?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\” width=\”100%\” height=\”100%\”> <s:layout> <s:BasicLayout/> </s:layout> <fx:Declarations> <s:SolidColor id=\”sc1\” color=\”0x00BFFF\” alpha=\”.3\”/> <mx:SolidColorStroke id=\”s1\” color=\”0x00BFFF\” weight=\”2\”/> </fx:Declarations> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; //组合图数据绑定 [Bindable] private var gridArray:ArrayCollection = new ArrayCollection([ {quarter:\”第一季度\”,Monday:\”78454\”,Tuesday:\”45454\”,Wednesday:\”12012\”,Thursday:\”78441\”,Friday:\”32314\”,Saturday:\”89454\”,Sunday:\”45421\”,Rate:\”23\”}, {quarter:\”第二季度\”,Monday:\”56444\”,Tuesday:\”65612\”,Wednesday:\”78454\”,Thursday:\”45124\”,Friday:\”35451\”,Saturday:\”45421\”,Sunday:\”65421\”,Rate:\”47\”}, {quarter:\”第三季度\”,Monday:\”51210\”,Tuesday:\”94210\”,Wednesday:\”65643\”,Thursday:\”45011\”,Friday:\”45122\”,Saturday:\”45421\”,Sunday:\”65988\”,Rate:\”13\”}, {quarter:\”第四季度\”,Monday:\”61210\”,Tuesday:\”45122\”,Wednesday:\”65323\”,Thursday:\”95110\”,Friday:\”65623\”,Saturday:\”45111\”,Sunday:\”65311\”,Rate:\”17\”} ]); ]]> </fx:Script> <mx:VBox width=\”100%\” height=\”100%\”> <mx:ColumnChart id=\”chart\” width=\”100%\” height=\”90%\” showDataTips=\”true\” fontSize=\”16\” dataProvider=\”{gridArray}\”> <!–设置水平坐标轴–> <mx:horizontalAxis> <mx:CategoryAxis dataProvider=\”{}\” categoryField=\”quarter\”/> </mx:horizontalAxis> <!–设置左竖直坐标轴的最大值和最小值–> <mx:verticalAxis> <mx:LinearAxis minimum=\”0.00\” maximum=\”100000.00\”/> </mx:verticalAxis> <!–设置左竖直坐标轴的柱形图–> <mx:series> <mx:ColumnSeries id=\”column1\” xField=\”quarter\” yField=\”Monday\” displayName=\”星期一\”/> <mx:ColumnSeries id=\”column2\” xField=\”quarter\” yField=\”Tuesday\” displayName=\”星期二\”/> <mx:ColumnSeries id=\”column3\” xField=\”quarter\” yField=\”Wednesday\” displayName=\”星期三\”/> <mx:ColumnSeries id=\”column4\” xField=\”quarter\” yField=\”Thursday\” displayName=\”星期四\”/> <mx:ColumnSeries id=\”column5\” xField=\”quarter\” yField=\”Friday\” displayName=\”星期六\”/> <mx:ColumnSeries id=\”column6\” xField=\”quarter\” yField=\”Saturday\” displayName=\”星期七\”/> <mx:ColumnSeries id=\”column7\” xField=\”quarter\” yField=\”Sunday\” displayName=\”星期八\”/> </mx:series> <!–设置右竖直坐标轴的最大值和最小值–> <mx:secondVerticalAxis> <mx:LinearAxis minimum=\”0.00\” maximum=\”100.00\”/> </mx:secondVerticalAxis> <!–设置右竖直坐标轴的折线–> <mx:secondSeries> <mx:LineSeries id=\”line\” dataProvider=\”{gridArray}\” xField=\”quarter\” yField=\”Rate\” displayName=\”比率\”/> </mx:secondSeries> </mx:ColumnChart> <!–设置Legend属性–> <mx:HBox> <s:Label width=\”25\”/> <mx:Legend dataProvider=\”{chart}\” fontSize=\”20\” width=\”100%\” height=\”30\” direction=\”horizontal\” horizontalGap=\”45\” verticalGap=\”45\”/> </mx:HBox> </mx:VBox> </s:Application> 3、显示结果
