A histogram can be displayed from any node to show the distribution of the observations in that subset of the data. A histogram is a graph of the number of times different observations fall into different response ranges. In the case where a histogram is displayed for a parent node that has several daughters, a stacked histogram plot is created that shows the parent on top, followed from left to right by the daughter histograms. The histogram displays can be modified through zooming in and out and changing the bin width. Finally, histograms can be saved as images and printed.
