在项目统计界面，我们离不开对Echarts的使用，接下来是我在做项目过程中做的一个关于温湿度统计的好看折线图，统计的是温度蓝色和湿度绿色，它们还会有告警和断电，分别用橘黄色和红色区分，以下是示例：
下载Echarts
//npm
npm install echarts --save
//淘宝镜像cnpm(安装速度快)
cnpm install echarts --save
//yarn
yarn add echarts代码案例
<template>
<div id="echartsOne" style="width: 100%;height: 100%;"></div>
</template>
<script setup>
import * as echarts from 'echarts';
import { onMounted,ref } from 'vue';
onMounted(()=>{
getEcharts();
})
const getEcharts = () => {
let chartDom = document.getElementById("echartsOne");
let myChart = echarts.init(chartDom);
