需要得到的代码如下：
series: [{name: '棒号1',data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]}, {name: '棒号2',data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]}, {name: '棒号3',data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]}, {name: '棒号4',data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]}]
这边的data中的值全部都是数组，而我在后台处理过程中最多可以将每个数组中的数据用json传到js中，这样遇到一个问题，就是json传过去的数据为字符串类型而series中data需要的是数组。
参照了网上的很多例子（说句真的，网上的例子真的不多，而且几乎都是一样的），如：

这个方法是先将需要读取的数据写在页面上，然后直接读取页面上的数据就可以了，但是不同项目的具体需求不净相同，我做的项目不可能在页面加载时就取到所需要的数据。没办法用了个最笨的办法，就是一个一个的赋值，这样效率是不咋地，还好每次只查询最多3条数据。
如果哪位大侠看到我这篇拙文，并且有更好的解决办法，还请赐教啊，本人不胜感激，QQ：848342187
附（我的解决代码）：
//js定义二维数组
var treeCol = new Array();
for (var i = 0; i < 15; i++) {
//二维数组赋值
treeCol[i] = new Array();
for (var j = 0; j < count; j++) {
treeCol[i][j] = 0;
}
}
series: [
//省略相同代码
{
name:'棒号2',
data: (function () {
return treeCol[1] == undefined ? 0 : treeCol[1];
})()
}, {
name:'棒号1',
data: (function () {
return treeCol[0] == undefined ? 0 : treeCol[0];
})()
}]
