代码:
注意:
①要实现这种效果,地图数据的name一定要是省份的名字,要不然颜色出不来;
②一定要有visualMap配置,并且它的seriesIndex属性 对应的是series的数组下标;

注意:
①一定要有geo这个配置,要不然光圈出不来。
并且series中的 type: “effectScatter”,的属性中一定要加上 coordinateSystem: “geo”,
② 然后对应的series中 这几个样式一定要加,加上才有那种光圈的效果

这个差不多就是上面两个的结合
但这种方法比较有趣的一点就是不需要写中国全省和各市的地理坐标,也就是说不需要我们手动提取出来他们的坐标,而是通过方法自动获取到,这一点就很有意思。

下钻后:
遇到的比较难解决的问题:
从全国地图下钻到安徽省的地图,安徽省的地图会小很多,修改了数据和json包发现都不行,但别人的echarts安徽省的图可以,就是很奇怪,找不到原因。解决的办法就是不同的地图设置不用的中心点和缩放比例。

页面效果其实很普通,不是说多惊艳,炫酷,只是这个引入全国,全省,全市json的方法很好,值得收藏。
安装 province-city-china 依赖。
npm i province-city-china -S
const { province, city } = require(‘province-city-china/data’);
同时在assets中引入文件,这样就可以动态的引入,自动区别哪个json的内容
