Constructors
ClusterItemGenerator()
Initializes a new instance of the ClusterItemGenerator class.
Declaration
public ClusterItemGenerator()Properties
AutoExpandWhenSingle
Gets or sets value which indicates whether cluster should be automatically expanded when it contains 1 data item only.
CloseDistance
Gets or sets array of the doubles which define close distance between 2 locations in degrees for every zoom level.
Declaration
public double[] CloseDistance { get; set; }Property Value
double[]
Remarks
If distance between 2 locations for the given zoom level is less than value in the array, then we consider these 2 locations as close ones. Close locations should be combined into 1 cluster.
DataMappings
Gets the value mappings that constitute the data mappings for a layer.
Declaration
public DataMappingCollection DataMappings { get; }Property Value
DeleteWhenEmpty
Gets or sets value which indicates whether cluster should be deleted if it is empty.
ExpandRadius
Gets or sets radius (in pixels) which will be used to calculate coordinates of the items when cluster is expanded to the polygon vertices.
HideExpanded
Indicates whether expanded cluster should be hidden.
