这是我找到的说明http://blog.ethereal-engineering.com/2013/01/heatmaps-using-gheat-and-gmap.html。
我怎样才能添加这个
private decimal? weight;
private object data;
public decimal? Weight { get { return weight; } set { weight = value; } }
public object Data { get { return data; } set { data = value; } }
到 GMap.NET 参考的类。
