echarts最新版如何在项目中使用，针对requireJs路径有关问题

echarts自从2.18版本后引入了全新的单文件打包构建策略 导致在实际项目中引入的时候有很多问题解决办法

1、requireJs引入echarts，采用包引入packages，如：

packages: [
	           {
	               name: 'echarts',
	               location: 'lib/thirdparty/echarts/src',
	               main: 'echarts'
	           },
	           {
	               name: 'zrender',
	               location: 'lib/thirdparty/zrender/src', // zrender与echarts在同一级目录
	               main: 'zrender'
	           }
	       ],

 2、调用init方法，参数dom元素使用document.getElementById获取需要渲染的区域

 3、可能产生的错误：1）、ComponentClass is undefined 解决办法：把图表使用的标签模块化。

    var componentLibrary = require('./component');
            componentLibrary.define('title', require('./component/title'));
            componentLibrary.define('tooltip', require('./component/tooltip'));
            componentLibrary.define('legend', require('./component/legend'));
            componentLibrary.define('axis', require('./component/axis'));
            componentLibrary.define('base', require('./component/base'));
            componentLibrary.define('dataView', require('./component/dataView'));
            componentLibrary.define('dataZoom', require('./component/dataZoom'));
            componentLibrary.define('grid', require('./component/grid'));
            componentLibrary.define('legend', require('./component/legend'));
            componentLibrary.define('polar', require('./component/polar'));
            componentLibrary.define('timeline', require('./component/timeline'));
            componentLibrary.define('toolbox', require('./component/toolbox'));
            componentLibrary.define('valueAxis', require('./component/valueAxis'));
            componentLibrary.define('dataRange', require('./component/dataRange'));
            componentLibrary.define('roamController', require('./component/roamController'));

 2）XX has not been required. 未加载相应的js模块，在echarts.js 文件中找到

var chartLibrary = require('./chart');

添加你需要加入的模块，

 chartLibrary.define('line', require('./chart/line'));
            chartLibrary.define('map', require('./chart/map'));
