Complete the following steps to specify the data for your graph.

- In Graph variables, enter multiple columns of numeric or date/time data that you want to graph.
- In Categorical variables for grouping (1-3, outermost first), enter up to four columns of categorical data that define groups. The first variable is the outermost on the scale and the last variable is the innermost.
- Under Scale Level for Graph Variables, select one of the following:
- Graph variables displayed outermost on scale: Graph variables are the outermost groups and the categorical variables are the innermost groups. On the graph below, graph variables are outermost on the scale.
- Graph variables displayed innermost on scale: Graph variables are the innermost groups and the categorical variables are the outermost groups.

This worksheet contains the fill weights for a food product each week for three weeks, and the machines that filled the product. Week 1, Week 2, and Week 3 are the graph variables. Machine is the categorical variable for grouping. The graph shows the confidence interval for the mean fill weight for each machine, clustered by week.
