Echarts中自定义地图

时间:2024-04-04 07:01:07

在Echarts中,我们很多时候是只需要自己想要的几个区域的地图,这时候提供的地图就不能满足我们的需求,需要我们自己来构建自己想要的地图。

1、首先我们申明一个json对象

var myjson={"type": "FeatureCollection",
"features":
[
{"type": "Feature","properties":{"id":"11","name":"北京","cp":[116.4551,40.2539],"childNum":19},"geometry":{"type":"Polygon","coordinates":[[[117.4219,40.21],[117.334,40.1221],[117.2461,40.0781],[116.8066,39.9902],[116.8945,39.8145],[116.8945,39.6826],[116.8066,39.5947],[116.543,39.5947],[116.3672,39.4629],[116.1914,39.5947],[115.752,39.5068],[115.4883,39.6387],[115.4004,39.9463],[115.9277,40.2539],[115.752,40.5615],[116.1035,40.6055],[116.1914,40.7813],[116.4551,40.7813],[116.3672,40.9131],[116.6309,41.0449],[116.9824,40.6934],[117.4219,40.6494],[117.2461,40.5176],[117.4219,40.21]]]}},

]
};

2、用上面申明的json对象注册地图

echarts.registerMap('mymap', myjson);

3、接下来使用地图的时候,我们就可以使用我们刚才注册的mymap地图了。
