Change Variable Roles
Separate Variables into Groups
When you add a categorical variable to the Group X or Group Y zone, a partition is created for each level of
the variable.
When you add a continuous variable to a grouping zone, Graph Builder uses quantiles of the data to divide
the variable into five groups. Once the variable is added to the display, you can change the number of groups
as follows:
1. Right-click on the grouping variable label and select Number of Levels.
2. Type in the number of levels that you want to display.
3. Click OK.
Change Variable Roles
To change variable roles, perform one of the following methods:
• Drag and drop a variable from one zone to another.
• Right-click on a variable in a zone and select Swap. Select the variable that you want to switch with.
Remove Variables
To remove a variable, perform one of the following methods:
• Drag and drop a variable into blank space.
• Right-click on a variable in a zone and select Remove.
Add Multiple Variables to the X or Y Zone
You can assign more than one variable to the same drop zone. By visualizing multiple Y variables across
multiple X variables, you can discover multivariate relationships and interactions.
To add a variable to the left or right of the existing X variable, drag and drop the variable into the X zone.
Use the same method for adding a variable to the top or bottom of the existing Y variable.
When you click and drag a variable, a blue shape appears, symbolizing where the variable is added. The
following table illustrates what each shape looks like for each task.
