Complete the following steps to specify the data for your graph.
From Function, select the function of the graph variables that you want to 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.
Select Stack values of last categorical variable to stack the multiple-level groups. If this option is not selected, Minitab displays the multiple-level groups as clustered bars.
From 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 that was produced each week for three weeks, on two machines. Week 1, Week 2, and Week 3 are the graph variables, and Machine is the categorical variable. The graph shows the means of the fill weights produced each week, stacked by machine.
