Bing 地图上的叠加图钉 - 如何显示两者的元数据或以特定缩放将图钉分开

Question

我正在从 Access365 数据库生成一个 HTML/Javascript 文件，该文件在 Bing 地图上绘制图钉。每个图钉都有关于其固定位置的关联元数据，可通过单击图钉查看。但是，可能存在位于完全相同位置（纬度和经度）的图钉，并且只有顶部图钉的元数据可用。

当用户将鼠标悬停在图钉上时，如何显示组合的元数据或让图钉分开一点？有谁知道这是怎么做到的吗？我在 MS 文档中兜了一圈，找不到任何帮助。

P.S。还有一个 clusterLayer。如果那需要移除来解决问题那没关系，但如果它能留下会更好。

当您有集群并且想要查看集群中项目的单个元数据时，有两种常用方法：

有一个弹出窗口显示集群中每个项目的第一个位置元数据和按钮 step/page/tab。
