EChart 关于图标控件的简单实用

１．下载前段框架并放入项目中去．

２．在js中调用

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>ECharts</title>
</head>

<body>
	<!--Step:1 Prepare a dom for ECharts which (must) has size (width & hight)-->
	<!--Step:1 为ECharts准备一个具备大小（宽高）的Dom-->
	<div id="main"
		style="height: 500px; border: 1px solid #ccc; padding: 10px;"></div>
	<div id="mainMap"
		style="height: 500px; border: 1px solid #ccc; padding: 10px;"></div>

	<!--Step:2 Import echarts.js-->
	<!--Step:2 引入echarts.js-->
	<script src="${base.contextPath}/js/echarts.js"></script>
	<script type="text/javascript"
		src="${base.contextPath}/js/jquery-1.6.2.min.js"></script>
	<script type="text/javascript">
		// Step:3 conifg ECharts's path, link to echarts.js from current page.
		// Step:3 为模块加载器配置echarts的路径，从当前页面链接到echarts.js，定义所需图表路径
		require.config({
			paths : {
				echarts : '${base.contextPath}/js'

		});

		// Step:4 require echarts and use it in the callback.
		// Step:4 动态加载echarts然后在回调函数中开始使用，注意保持按需加载结构定义图表路径
		$(document).ready(

					});
				});
		// bar(null);
		function bar(data) {
