Question

我正在创建一个使用apiv3 for Google Maps的可视化。目前，我在地图上绘制了几千个多边形，还有一些标记。问题是我试图绘制的一些区域被认为是“多重多边形”。例如，投票区有多个区域，这些区域是分开的，而不是连接在一个多边形中。我该如何画这个？

试过这个，但它似乎没有渲染。

var Poly14591; 
var outer = new google.maps.MVCArray([new google.maps.LatLng( 42.862496, -78.151154), new google.maps.LatLng( 42.862251, -78.151319), new google.maps.LatLng( 42.86189, -78.151538), new google.maps.LatLng( 42.861765, -78.151647)]);


var inner = new google.maps.MVCArray([new google.maps.LatLng( 42.867545, -78.151817), new google.maps.LatLng( 42.866978, -78.151813), new google.maps.LatLng( 42.866044, -78.151787), new google.maps.LatLng( 42.864956, -78.151712), new google.maps.LatLng( 42.864231, -78.151709), new google.maps.LatLng( 42.863593, -78.151708)]);

var paths = new google.maps.MVCArray([outer, inner]);

Poly14591 = new google.maps.Polygon({paths:paths,  strokeOpacity: 10.0, strokeWeight: 20, strokeColor: "#FF0000", fillColor: "#FF0000", fillOpacity: 0.35}); 

 Poly14591.setMap(map);

这实际上似乎允许我映射单独的多边形，这些多边形实际上仍然在单个谷歌地图多边形对象的上下文中。
