最近要用到图表展示，想了想，还是首选Echarts，HighCharts和D3.js备用吧，
而项目中也用到了AngularJS，所以需要把Echarts引入到AngularJs中一起使用，
试了试，最方便的还是用指令，（虽然指令有点不好调，用了再说）。
1、引入angular.js
2、引入echarts.js
3、引入jquery.js---可以省略
4、直接上代码：
1 <!DOCTYPE html >
2 <head>
3 <meta charset="utf-8">
4 <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
