简介 Flex实现双轴组合图的设计思路及代码_Flex_
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：
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="100%" height="100%">
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"}
]);
