常规用法，就不细说了，按照官网一步步来。
本文主要解决问题（已参考网上其他文章）：
1、把echarts给扩展到JQuery上，做到更方便调用。
2、多图共存
3、常见的X轴格式化，钻取时传业务实体ID的问题
先上图：页面加载时，（第一个图不可以钻取，第二个可以钻取）
2、我们先点击第二个图，进行钻取，如下
3、点击左上角按钮，动态为第一个图添加点击钻取事件，然后点击第一个图进行钻取
1、html页面如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Button1" type="button" value="动态添加事件到Company图表" onclick="return Button1_onclick()" /><br />
当前显示：<div id="message">
</div>
</div>
<div id="bar_company" style="height: 250px; width: 800px; background-color: Lime;">
</div>
<div id="bar_labors" style="height: 250px; width: 800px; background-color: Gray;">
</div>
</form>
<script src="Component/jquery-1.9.1.js" type="text/javascript"></script>
<script src="Component/esl.js" type="text/javascript"></script>
<script src="Component/echartsadapter.js" type="text/javascript"></script>
<script>
$(document).ready(function () {
$('#bar_company').echarts({ query: { cmd: "company", company: 1 }, settings: { chartType: "line"} });
$('#bar_labors').echarts({ query: { cmd: "labors", labor: 1 }, settings: { chartType: "bar", onclick: labor_Click} });
});
function company_Click(param) {
var options = $('#bar_company').echarts('options');
showClickInfo(param, options);
}
function labor_Click(param) {
var options = $('#bar_labors').echarts('options');
showClickInfo(param, options);
}
function showClickInfo(param, option) {
var message = "您点击了：" + option.title.text + "<br/>"
+ "点击位置：seriesIndex：【" + param.seriesIndex + "】DataIndex：【" + param.dataIndex + "】,<br/>"
+ "当前点击Series:【" + param.seriesName + "】节点:【" + param.name + "】数据【" + param.data + "】";
$('#message').html(message);
}
function formatCompany(cid) {//格式化X轴显示
var labels = $('#bar_company').echarts('labels');
if (labels) return labels[cid];
return cid;
}
function Button1_onclick() {
$('#bar_company').echarts({ settings: { onclick: company_Click} }); //echarts绘制出来后，手动添加事件
}
function test() {
//使用方法：
//1、获取查询的业务参数：$('#mydivid').echarts('query');
//2、获取设置参数信息$('#mydivid').echarts('settings')
//2、获取echarts的option:$('#mydivid').echarts('options')
//3、获取echarts的echart相关对象:$('#mydivid').echarts('echarts') //获取到的对象格式 { echarts: ec, chart: null, config: null };
//4、获取echarts的X轴的labels:$('#mydivid').echarts('labels') //获取到的对象格式{1001:'first data',1002:'second data'}
}
</script>
</body>
</html>
2、echartsAdapter.js
//$("").echarts({ query: { id: 1, name: 'zxh' }, settings: { onclick: function () { } } });
//data 中会有:query,settings,echarts,labels,options
(function ($) {

var settings = $.extend({}, $.fn.echarts.defaults, arg.settings);
$this.data('settings', settings);
if (init) {//chart初始化
echartsInit.apply(this); //不应用设置
return $this;
}
if (!init && arg.query) {//重新请求data数据
echartsReload.apply(this);
return $this;
}
if (arg.settings) {
echartsApply.apply(this);
}
}
return $this;
};
function echartsApply() {
var $this = $(this);
var echarts = $this.data('echarts');
if (echarts && echarts.chart && echarts.config) {
if ($this.data('settings').onclick)
echarts.chart.on(echarts.config.EVENT.CLICK, $this.data('settings').onclick);
window.onresize = echarts.chart.resize;
}
}
function echartsInit() {
var $this = $(this);
var settings = $this.data('settings');
require.config({

}
}
//arguments
