教你如何透過vue實現echarts中的儀表盤

導讀	這篇文章主要為大家詳細介紹了vue實現echarts中的儀表盤，文中示例程式碼介紹的非常詳細，具有一定的參考價值，感興趣的小夥伴們可以參考一下

本文例項為大家分享了vue實現echarts中的儀表盤的具體程式碼，供大家參考，具體內容如下

最終結果

1. 首先需要安裝echarts依賴包

npm install echarts -S

2. 或者使用國內的淘寶映象：

npm install -g cnpm --registry=

全域性引入

main.js

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

Hello.vue

export default {
    data(){
      return {}
    }, 
     mounted(){
        this.myChart() //函式呼叫
     },
     methods:{
        myChart() {
        let columnar = this.$echarts.init(document.getElementById('myChart'));
        columnar.setOption({
