Categorized Line Plots - Advanced Tab

Graphical Analytic Techniques

Select the Advanced tab of the Categorized Line Plots Startup Panel to access a variety of options to use when creating categorized line plots including graph style, whether to use point markers, and which method of categorization to use. Categorization is used in two classes of graphs in Statistica: categorized graphs (e.g., Categorized Scatterplots) and graphs that include grouping or categorized variables (e.g., 2D Histograms, or 2D Box Plots).

Layout. Select the type of layout for the graph(s).

Separate

Select this option button to produce a Separate plot layout (where each subset of cases is displayed in a separate graph) for the categorized plots.

Overlaid

Select this option button to produce an Overlaid plot layout (where all subsets are overlaid in one graph and identified by patterns and colors) for the categorized plots.

Variables

Click the Variables button to display the standard variable selection dialog box, in which you can select the X and (optional) Y grouping variables and the variable(s) to be displayed in the line plots. If more than one dependent variable is selected, then a sequence of graphs (one for each dependent variable) will be produced using the same set of grouping variables. The selection that you make will then be displayed in the area of the dialog below the Variables button.

Note: the selected grouping variables do not have to be categorical variables (e.g., contain codes); you can use one of the methods of categorization to categorize continuous variables. The selection of grouping variables is not necessary if the categories are defined via the Multiple Subsets method.

X-Categories / Y-Categories

Select Integer mode, Unique values, or Categories to specify that method of categorization for each of the variables selected via the Change Variable button, or use the Boundaries, Codes, or Multiple subsets options.

Points

You can display the line plot with (On) or without (Off) point markers. If you select Auto, Statistica automatically determines the display of point markers depending on the number of observations and the closeness of the points (usually, if N>100, then the points are not displayed).
