文章以河南省为例
一、先下载eacherts相关js文件（echarts.min.js）和echarts使用到的地图插件（map）
ecarts.min.js在下载，map插件下载地址： （包含全国、各省城市）
二、代码
<script type="text/javascript" src="/home/js/jquery.js"></script>
<script type="text/javascript" src="/home/js/echarts.min.js"></script>
<-- 我这里用的是河南地图，可以根据自己需要选择城市-->
<script type="text/javascript" src="/home/js/map/js/province/henan.js"></script>
<script>
<--地址换成从github下载的文件路径-->
var uploadeddataurl = "/home/js/map/json/province/henan.json";
mychart.showloading();
$.getjson(uploadeddataurl, function(geojson) {
echarts.registermap('henan', geojson);
mychart.hideloading();
var geocoordmap = {
