可以啊，就画相邻两个点的直线，一直画完就是一条线了。下面是openlayers3的方法，你参考一下。创建图层我就不贴代码了，反正你可能用的不是openlayers
function view_gj(data){ //线路
for(let i = 0;i < data.length;i++){
if((i+1) == data.length){
return;
}
let feature_gj = new ol.Feature({
geometry:new ol.geom.LineString(
[data[i],data[i+1]])
});
feature_gj.setStyle(new ol.style.Style({
stroke: new ol.style.Stroke({
width: 3,
color: [0, 0, 255, 1]
})
}));
vectorSource_gj.addFeature(feature_gj);
}
}
@HongKongDoll，这不已经很简单了?打开就是源码.

你把
[116.362209, 39.887487],
[116.422897, 39.878002],
[116.372105, 39.90651],
[116.428945, 39.89663]
];```
改成你自己的点就好了
