These options are available in the Categorization dialog box as well as on the Categorization tab of the Graph Options dialog box, and are used for customizing the categorization of Categorized graphs.  

X intervals/Y intervals. Use the options in the X intervals and Y intervals group boxes to change categorization of the X and Y variables. You can choose from the following methods of categorization (for more details of these methods, see Method of Categorization).

On. Select the On check box in order to make the corresponding X intervals or Y intervals options available.

Integer mode. Select the Integer mode option button in order for each encountered value of the selected variable to be truncated to an integer value and create a category; several values can be truncated to the same integer value, thus falling into the same category.

Unique vales. Select the Unique values option button to create one category (or graph in the case of categorized graphs) for each unique value. The unique values can be either floating point or integral, and STATISTICA can handle up to 255 unique values.

Categories. Select the Categories option button to divide the entire range of values of the selected variable (from minimum to maximum) into the requested number of equal length intervals (Categories).

Boundaries. Select the Boundaries option button to create your own boundaries for the intervals. The Boundaries for the intervals (categories) are defined by the values you supply when you click the Specify Boundaries button; these intervals may not be of equal size.

Codes. Select the Codes option button to decide the categories according to the specified codes of the selected variable; the number of categories will be equal to the number of codes that you select. Note that to specify the codes, click the Specify Codes button.

Multiple subsets. Select the Multiple subsets option button and then click the Specify Subsets button to define the selection conditions that will create specific categories; more than one variable can be used to define a category. Note that if this categorization is used, then the current selection of the respective categorical variable will be ignored.

Change Variable/Specify Boundaries/Specify Codes/Specify Subsets. Note that the name of this button changes depending on the Interval option button that is selected. Click the Change Variable button to display a standard variable selection dialog box, which is used to change the selection of the grouping variable to which the Intervals options apply. Click the Specify Boundaries/Codes/Subsets button to display various dialog boxes in which you enter the boundaries, codes, or subsets that are used to create user-defined categories.

Properties. The options in the Properties group are used to select a special format (representation) in which to display the X and Y labels in your graph. Most of the options available for this purpose have more than one representation, except the General and Percentage options (see Value format). With some of the options, you can also specify decimal information.

X Intervals value format. Click the X Intervals value format button to display the Value Format dialog box; the display format chosen in that dialog box will be used to label the x-axis.

Y Intervals value format. Click the Y Intervals value format button to display the Value Format dialog box; the display format chosen in that dialog box will be used to label the y-axis.

Categories Layout. Choose either a Separate plot layout (in which each subset of cases is displayed in a separate small graph) or an Overlaid plot layout (in which all subsets are overlaid in one graph and identified only by patterns and colors) for the categorized graph.

Category/class names. Use the options in this group box to specify information about whether you want labels printed in the output graph.

From the drop-down list, select None if you do not want labels printed in the output graph. Select Category & class names to print these in the output graph. Select Class names only to print only class names in the output graph.

Font. Click this button to display the Font dialog box, where you can specify the font, size, etc., for the labels printed in the output graph.
