Graph > Histogram

A histogram shows the frequencies of a number of bins (or classes) with numerical boundaries. The width of each bin is the same. With this utility, you can create histograms that represent the frequences or relative frequencies of a set of bins. Any data value less than the minimum of all values will be assigned to the first bin, and any data value greater than the maximum will be assigned to the last bin. Values at bin boundary will be assigned to the higher bin.

The histogram graph utility allows the user to specify graph variables containing data values and optionally a group variable. It also provides the options of having a plot title, axis labels, and legend.
