Understanding How to Use the HISTOGRAM Statement
A histogram is similar to a vertical bar chart. This
type of bar chart emphasizes the individual ranges of continuous numeric
variables and enables you to examine the distribution of your data.
The HISTOGRAM statement
in a PROC UNIVARIATE step produces histograms and comparative histograms.
