Use to add, remove, or change the grouping variables on a scatterplot, matrix plot, or histogram.
Categorical variables for grouping: Enter up to three columns of grouping variables to assign different attributes for each group and display a legend.
Apply same grouping to other data displays: Check to update all data displays, such as symbols and project lines, to use the same grouping variables as the area. (Available for scatterplots and matrix plots. For histograms, Minitab automatically assigns the grouping variable to all data displays.)
