Vue Echarts实现多功能图表绘制的示例详解

2023-02-20 10:29:30 作者：dkjhl

作为前端人员，日常图表、报表、地图的接触可谓相当频繁，今天小编隆重退出前端框架之VUE结合百度echart实现中国地图+各种图表的展示与使用；作为“你值得拥有”专栏阶段性末篇，值得一看

前言

主要实现功能

中国地图
环形图
折线图
柱形图
复杂交互
单选复选

环境搭建

初始化环境参考：利用vue-cli搭建vue项目框架

项目部署

build project：

npm install

npm run build

npm run dev

访问地址：

http://localhost:8895/#/dashboard

项目结构
