*
* 修改后支持 柱形图(bar)、线形图(line)、饼形图(pie)
*
* @example:
*
* HTML代码部分：
* <script src="js/esl.js"></script>
* <body>
<!-- 线形图、柱形图显示 -->
<div id="chartArea" style="height:300px;border:1px solid #ccc;padding:10px;"></div>
<!-- 饼形图显示 -->
<div id="pieArea" style="height:300px;border:1px solid #ccc;padding:10px;"></div>
</body>
PHP代码部分：
// 柱形图、线形图模拟数据
$option = array(
"legend"=>array("邮件营销","联盟广告","视频广告","直接访问","搜索引擎"),
"xaxis"=>array("type"=>"category","boundaryGap"=>"true","data"=>array("周一","周二","周三","周四","周五","周六","周日")),
