Assigning Data to Roles

You can subset the data in the input data set by applying an SQL WHERE clause. In the Where string box, enter your valid SQL syntax. Operands that are character strings must be enclosed in single or double quotation marks. To view this WHERE clause with the resulting graph, select the Include as footnote check box.
To run the Histogram task, you must assign a column to the Analysis variable role.
You can specify whether to create a density curve that shows the distribution of values for a numeric variable. You can create density curves for normal and kernel distributions.
