前端绘制一个关于好评和投诉的仪表盘分数和百分比占比显示

一、效果图

二、使用

1. 通过 npm 安装 ECharts:

    npm install echarts --save
   1

2. 安装完成以后，可以将 echarts引入页面，这样我们就可以在该页面使用 echarts 所有组件

    import * as echarts from "echarts"
   1

3. 下面是代码，注意分辨哪些是自己需要的部分，不需要的直接删除。

<template>
  <div class="container_main">
 	<div class="container_main_Class">
      <div class="chartClass">
        <div class="leftClass">
          <div class="spanClass">
            <span>{{ dataMap2.goodValue }}&nbsp;次</span>
          </div>
          <div class="spanClass">
            <span>好评/默认好评</span>
