vue_echarts_0">vue 中echarts使用

通过 npm 获取 echarts，npm install echarts --save，

下载好echarts以后在main.js中全局引入 使用少的话可以早某个vue页面引入即可

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


//在template中创建div
<template>
   <div id="myChart" style="height:300px; padding-top:30px "></div>
</template>
export default {
    name: 'hello',
    data () {
      return {
        msg: 'Welcome to Your Vue.js App'
      }
    },
   mounted(){
      this.drawLine();
      thi.sbzt() /或者这样也行  看下面的方法
    },

    methods: {
      drawLine(){
