The histogram for the centroid attributes in a cluster is part of the Cluster Centroid Attributes in the Cluster Details display.
The attributes in the cluster centroid are displayed in the Cluster Centroid Attributes grid. For each attribute, the name, the centroid range, and the centroid value are displayed.
When this dialog is first displayed, the histogram for the first centroid attribute is displayed. To see a histogram for any other cluster centroid attribute, select the attribute name. The histogram is displayed in the bottom area of the display.
To see more information about a particular bar in the histogram, float the cursor over the bar; Series, Values, and Bin Count are displayed.
For categorical data, the histogram displays at most 5 bins of data and one Other bin. The maximum number of bins to display cannot be changed. It is possible for the centroid value to be "OTHER_CATEGORY".
To save the information about the attributes as a text file, click the "Save As" icon (a yellow arrow above a graphic of a page) above the attributes grid.
To save the histogram in GIF or PNG format, click the Save As icon (a yellow arrow above a graphic of a page) above the histogram.
