vue3大屏可视化项目，包含地图，各种 图表，全屏适配方案

项目设计
1.始终满屏适配，这种方案一般用在屏幕变化不会特别的大项目，项目基本上不会用在比例非常不协调的大屏，设计图按1920*1080标准电脑屏幕比，所用的屏幕也基本在这个比例左右
2.涉及图表知识点简单，主要有自定义色系，环形图，堆叠柱状图，折线图
3.使用高德地图标点做中间地图
满屏适配方案实现思路
1 宽度使用vw，高度使用vh，严格按照设计图换算，并且留出缓冲空间
2 具体算法，设计图为19201080
高度上：
1.设计图上量取高度
2.高度除以设计图高度1080
3得到结果100
4计算结果加上vh单位3
宽度上：
设计图上量取宽度
高度除以设计图高度1920
得到结果*100
计算结果加上vw单位
3 特别提醒，因为我们大屏项目，高度要始终保持一屏，一般移动端项目高度不用一屏，是可以滚动的，所以高宽统一VW
项目头部制作
<code>//
<template>
<div class="headerContainer">code>
<div class="header-title">大数据展示</div>code>
</div>
</template>
<script setup>
</script>
<style scoped>
.headerContainer{ -- -->
width:100vw;
height:6.85vh;
background-color: #030829;
.header-title{
color:white;
font-size: 1.01vw;
width:28.48vh;
height:100%;
line-height:6.85vh;
text-align:center;
margin: 0 auto;
background-image: url("../assets/logoBg.png");
background-size: 100% 100%;
}
}
</style>
项目请求和环境搭建
// request/index.js
import axios from 'axios'
const request = axios.create({
timeout:10000,
baseURL:import.meta.env.VITE_BASE_URL
})
request.interceptors.request.use((config) => {
return config
})
request.interceptors.response.use((res) => {
if(res.data.code !== 200){
alert("请求错误")
}
return res
},(res) => {
alert("请求错误")
throw new Error(res)
})
export default request
// api/index.js
import request from '../request/index.js'
export function getGather(){
return request.get("/getGather")
}
export function getChargeData(){
return request.get("/getCharGeData")
}
export function getOutpatient(){
return request.get("/getOutpatient")
}
export function hosiptalPostion(){
return request.get("/hosiptalPostion")
}
export function getHospitalization(){
return request.get("/getHospitalization")
}
在根目录创建.env.development和.env.production

在App.vue
