Cluster drawing on divided display region allocated to cluster

摘要

Clusters of metrics in a system are stored. A display region is divided into n divided regions in such a way that an area of a divided region i (1≤i≤n) is equal to or larger than an area of a divided region i+1. Each cluster is allocated to the divided region i sequentially selected from i=1, in the decreasing order of the number of metrics contained in each of the clusters, in such a way that the number of the clusters allocated to the divided region i+1 is equal to or more than the number of clusters allocated to the divided region i. The cluster allocated to the divided region i is drawn in the divided region i.
