For information about data considerations, examples, and interpretation, go to Overview for Line Plot.
Enter a numeric or text column that defines the points in the line chart.
From Function, select the function of the Summarized variables. For example, if you select Maximum, Minitab defines the color for the graph based on the maximum value of the summarized variables. If you enter a text column in Summarized variables, you can only select Percent equal to specified values, Number of nonmissing values, or Number of missing values.
Enter a categorical variable that defines the x axis.
When you enter multiple Summarized variables, you can choose one of the following layout options.
Enter a variable that defines the groups. Group labels are shown in the graph legend.
When you enter multiple By variables, Minitab enables the Show all combinations checkbox. Select this option to create a separate plot for each combination of groups created by the By variables. If you do not select this option, Minitab creates a plot for each group of each By variable.
For example, the first By variable has 2 groups, Male and Female, and the second By variable has 2 groups, Employed and Unemployed. If you select Show all combinations, Minitab creates 4 separate plots for the combinations of Male/Employed, Male/Unemployed, Female/Employed, and Female/Unemployed. If you do not select Show all combinations, Minitab creates 4 separate plots for Male, Female, Employed, and Unemployed.
Select to display a symbol at each point on the x-axis. If you do not select this option, the graph displays only the lines.
Select this option to change the Y-scale type to percent.
