Minitab offers several ways to display groups on your graph; however, not all the options are available for all graphs or worksheet arrangements.
Overlaid groups are effective when you have relatively few categorical levels, or if relatively small differences are visible if the groups share the same graph.
Paneling can be effective, for example, when you want to show the distinction between many categorical levels, or when data displays overlap (as with histograms).
Display each group on a separate graph when you want to examine one group at a time.
In a worksheet, groups can be determined by a grouping variable (stacked data), or by separate columns for each group (unstacked data).
Groups are determined by a grouping variable; also known as a By variable. In the following worksheet, the grouping variable is Gender and the groups are Weight vs Height for Female (F) and Weight vs Height for Male (M).
Each column, or X-Y column pair for scatterplots, is a group. In the following worksheet, the groups are Weight Female vs Height Female and Weight Male vs Height Male.
|Height Male||Height Female||Weight Male||Weight Female|
