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 |
