echart绘制中国地图及各省份地图

示例:

 

 地图文件下载地址:https://gitcode.net/mirrors/fuhang-lm/echarts?utm_source=csdn_github_accelerator&from_codechina=yes

 

这里以北京市地图为例,如果是其他省份或者全国,下载对应的js文件并引入系统,需要替换一下两处,换成对应的省份:

?
1
2
var mapName = '北京'
geo: { map: '北京',}

 名字命名在对应的js文件里,需要写对,地理坐标js文件也有,复制出来就可以了

 

html

<div id="chart_map" style="width:100%;height:610px;"></div>

<div id="chart_bjmap" style="width:100%;height:610px;"></div>


...省略...
