Patent ID: 6847381

Claim:
A method of displaying a dendrogram representing quantified relations among elements of a group of elements, the method comprising the steps of: creating a plurality of types of dendrograms based on the same group of elements according to different inter-element relation quantification methods and/or different dendrogram creation methods; selecting one of the plurality of types of dendrograms as a reference dendrogram; converting another dendrogram such that the order of its elements is the same as that of the reference dendrogram; and displaying the reference dendrogram and the converted dendrogram in an overlapped manner by aligning a direction from branches to leaves of the reference dendrogram and that of the converted dendrogram in parallel and with an identical orientation thereby sharing the elements, wherein nodes, branches and leaves of the plurality of types of dendrograms that are displayed do not overlap one another, and the order of elements of a branch in a selected dendrograms can be changed starting from a specified node.
