Polarisone 人气:3最终结果
一、安装
1. 首先需要安装echarts依赖包
npm install echarts -S
2. 或者使用国内的淘宝镜像：
npm install -g cnpm --registry=https://registry.npm.taobao.org
二、创建图表
全局引入
main.js
// 引入echarts import echarts from 'echarts' Vue.prototype.$echarts = echarts
Hello.vue
<div id="myChart" :style="{width: '300px', height: '300px'}"></div>export default {
data(){
return {}
},
mounted(){
this.myChart() //函数调用
},
methods:{
myChart() {
let columnar = this.$echarts.init(document.getElementById('myChart'));
columnar.setOption({

formatter: "{a} <br/>{c} {b}"
},
