引入命令：

npm install echarts --save

全局引入：

在main.js中写入：

import echarts from 'echarts'
Vue.prototype.$echarts = echarts

在其他页面用到echarts时，需要先有一个HTML标签：(id不可缺少)

 <div id="monthorder" style="width:100%;height:300px"></div>

接下来echart的应用方式为：

var myechart = this.$echarts.init(document.getElementById("monthorder"));

按需引入：

在需要用到的页面引入，以饼状图为例：

//引入echart
var echarts = require("echarts/lib/echarts");
//引入饼状图
require("echarts/lib/chart/pie");
//引入title等等
require("echarts/lib/component/tooltip");
require("echarts/lib/component/title");
require("echarts/lib/component/legend");
require("echarts/lib/component/legendScroll");

然后就是按照网上一般的写法写就行，
