Creating a Centroid Plot



A centroid plot can be used to visualize the centroid or exemplar profile for each of the clusters resulting from a partitional clustering experiment. For example, if you select a K-Means clustering experiment where K=5, a centroid plot of it shows 5 profiles. Each profile represents the average value for all of the members of one of the clusters.

By selecting one or more cluster centroids and then launching a cluster plot, it is possible to visually 'drill down' into the clusters to view the individual member profiles.



1. Click a Partitional Clustering experiment in the Experiments navigator. The item is highlighted.

2. Select Centroid Plot from the Clustering menu, or right-click the item and select Centroid Plot from the shortcut menu. A plot of all cluster centroids is displayed.
