这篇文章主要是说明怎么实现vue+echarts实现地图的，一些基础的API建议去查阅echarts官方文档，这里主要说明怎么获取地图数据并应用数据生成地图，实现一些常见的交互操作
echarts常见配置项
官网：https://echarts.apache.org/zh/index.html
- 如果是options中的一些基础配置项，直接查阅官网-文档-配置项
- 如果是事件events和action，查阅官网-文档-API
地图geoJson下载地址
- 下载地址（可以下载svg或json格式的地图数据）：http://datav.aliyun.com/tools/atlas/#&lat=30.772340792178525&lng=103.94573258937584&zoom=9.5
将下载后的json文件放置/public目录下

geo类型地图
geo类型其实和map差不多，区别在于它可以绘制散点和线集，还支持轨迹动画

坑
报错："export 'default' (imported as 'echarts') was not found in 'echarts'
原因：echarts v5版本不再是用默认导出的方式，所以import echarts from 'echarts'方式报错
解决：npm unstaill echatsnpm install echarts@4.9.0
或者：使用5版本的写法--import * as echarts from 'echarts';TypeError: coordSys.getBaseAxis is not a function
series中的type写错了，把lines写成了line，改过来就好

坑
- BMap api is not loaded
原因：在mounted初始化地图的时候，因为异步问题会导致BMap is not defined，也就是百度的api还没完全引入或者加载完成，就已经进行地图初始化了
参考：https://www.cnblogs.com/menxiaojin/p/13613607.html
- 设置mapStyle个性化样式不生效：待解决
