ClusterMethod

Unit:SDL_dendrogram
Class:TDendrogram
Declaration:property ClusterMethod: TClusterMethod;

The property ClusterMethod controls the type of clustering method used to create the dendrogram:

cmSingleLink single linkage
cmCompleteLink complete linkage
cmWard Ward's method (in most cases this method produces dendrograms which are nice to look at)
cmAvgLink average linkage
cmFlexLink flexible approach; you have to use the property FlexAlpha to adjust the clustering mode.
cmUpgma unweighted pair group with arithmetic mean

Hint: Changing the property ClusterMethod triggers the recalculation of the dendrogram. In order to prevent multiple recalculations if several clustering parameters are to be changed, the property SuppressClustAnal should be set to TRUE prior to changing any parameters of the clustering algorithm.

Example: This property is used in the following example program (see http://www.lohninger.com/examples.html for downloading the code): dendro
