我不能在相同的坐标上创建多个图层（图像和线条）。 有谁知道你怎么处理它？</ p>
示例代码：
for (; index_array < array_trip.length; index_array++) {
latVal = array_trip[index_array].latitude;
longVal = Microsoft.Maps.Location.normalizeLongitude(array_trip[index_array].longitude);
map.setView({ center: new Microsoft.Maps.Location(latVal, longVal) });
var pushpinOptions = { icon: path + 'car.png', width: 50, height: 50 };
var pushpin = new Microsoft.Maps.Pushpin({ latitude: latVal, longitude: longVal }, pushpinOptions);
map.entities.push(pushpin);
}

首先，不要在数组中设置地图视图。这只会导致问题。其次，确保图钉图标的URL正确无误。也许现在尝试删除该选项，直到您看到地图上显示的默认图钉，然后尝试添加自定义图标。
如果您想将数据分成多个图层，则应使用EntityCollection＆＃39; s：https://msdn.microsoft.com/en-us/library/gg427616.aspx
以下是关于分层的好文章：https://rbrundritt.wordpress.com/2011/10/13/multiple-pushpins-and-infoboxes-in-bing-maps-v7/

使用可以初始化EntityCollection object一次向地图添加多个实体。
示例
function GetMap() {
var locations = [
new Microsoft.Maps.Location(60.173783, 24.941068),
new Microsoft.Maps.Location(59.338575, 18.065823),
new Microsoft.Maps.Location(59.922602, 10.749411),
new Microsoft.Maps.Location(55.675817, 12.570452)
];
var map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), { credentials: "Bing Maps Key" });
//1. Add pushpins
for (var i = 0; i < locations.length; i++) {
var pin = new Microsoft.Maps.Pushpin(locations[i]);
// Add the pushpin
map.entities.push(pin);
}
//2. Add a polyline
var line = new Microsoft.Maps.Polyline(locations);
map.entities.push(line);
//3. Add a polygon
var polygoncolor = new Microsoft.Maps.Color(100, 100, 0, 100);
var polygon = new Microsoft.Maps.Polygon(locations, { fillColor: polygoncolor, strokeColor: polygoncolor });
map.entities.push(polygon);
var bestview = Microsoft.Maps.LocationRect.fromLocations(locations);
map.setView({ bounds: bestview });
