Extjs 桑基图绘制实现（前端+后端）

桑基图效果如下：

准备工作：

1、新建 SanKey. ，如下所示，将对于部分删除。

删除多余部分，保留头部如下：

2、新建 SanKey.html 页面，如下所示；

在html页面中添加如下信息：

<!DOCTYPE html PUBLIC -//WC//DTD XHTML 1.0 Transitional//E .dtd>
<html xmlns=>
<head><title></title><meta http-equiv=Content-Type content=text/html; charset=utf-8 /><script src=Scripts/bootExtJS.js type=text/javascript></script><script src=Scripts/Jquery/js type=text/javascript></script><script src=Scripts/ECharts4.0.2/js type=text/javascript></script><script src=Scripts/SanKey.js></script>
</head>
<body><div id=main1 style=float: left; width: 100px; height: 800px; background-color: #efefef;><div id=pic1 style=float: left; width: 1000px; height: 600px; background-color: #efefef;></div></div>
</body>
</html>

、新建SanKey.js文件,如下：

/*
* 
* 页面前台
*
* 页面：桑吉图
* 作者：凌霜残雪
*
*/
(function () {//开启提示功能Ext.QuickTips.init();//通过ajax发送添加请求Ext.Ajax.request({url: SanKey.aspx?method=GetData,method: 	POST	,success: function (respe) {var data = respe.respeText;if (data !=  && data != null) {var pic1 = echarts.init(document.getElementById(	pic1	));var eValue = eval(	(	  data  	)	); //要先转换pic1.setOption(option = {title: {text: 	工厂能耗桑基图(功率kW)	,left: 45,textStyle:{fontSize: 20}},tooltip: {trigger: 	item	,triggerOn: 	mousemove	},series: [{type: 	sankey	,layout: 	none	,data: ,links: eValue.links,itemStyle: {normal: {borderWidth: 1,borderColor: 	#aaa	}},lineStyle: {normal: {color: 	source	,curveness: 0.5}},top: 20}]});}}});//页面总布局var viewport = (	Viewport	, {layout: 	border	,items:[{region: 	center	,border: 0,bodyStyle: 	padding: 10px; background-color: #efefef; overflow-y: auto; overflow-x: hidden;	,layout: 	fit	,contentEl: 	main1	}]});
});

4、后端SanKey.aspx 代码如下：

using System.Reflection;
using System.Web;
using System.Web.Script.Serialization;
using System.Web.UI;
