For information about data considerations, examples, and interpretation, go to Overview for Histogram.
Enter one or more numeric columns that you want to graph.
Choose one of the following layout options.
Enter a variable that defines the groups. Group labels are shown in the graph legend.
When you enter multiple By variables, Minitab enables the Show all combinations checkbox. Select this option to create a separate histogram for each combination of groups created by the By variables. If you do not select this option, Minitab creates a plot for each group of each By variable.
For example, the first By variable has 2 groups, Male and Female, and the second By variable has 2 groups, Employed and Unemployed. If you select Show all combinations, Minitab creates 4 separate plots for the combinations of Male/Employed, Male/Unemployed, Female/Employed, and Female/Unemployed. If you do not select Show all combinations, Minitab creates 4 separate plots for Male, Female, Employed, and Unemployed.
Select how you want to display the y-scale.
Make the Y-scale the same across multiple graphs.
Make the X-scale the same across multiple graphs.
