A crosstab is a statistical process that summarizes categorical data from one or more sources in a concise format for analysis or reporting. It usually represents the joint distribution of two or more variables in compact row and column format. In business intelligence, engineering, survey and scientific research, the crosstab is widely used.
In JReport, crosstabs are data containers, which means that when a crosstab is inserted into another data container, you can set up data container link between the crosstab and its parent (for details, see the section Setting up data container link).
