This pop-over dialog is shown when clicking either the button to the right of either the Rows or Columns labels on the Crosstabs view toolbar. The default Row attribute is $Name, and for columns it is $Height.
Search box. Type the name of an attribute (with auto-completion) to locate the group/name of the desired attributes. Pressing Return with a valid attribute name will correctly configure the group and name pop-ups below.
Maximum Bins. Either type a number in the box (between 1 and 24) or use the up/down control to set the desired number of bins for distribution of the results in the crosstab matrix.
Unlimited Bins. Tick this to override the above control and to show as many bins as there are discrete values (e.g. for String-based attributes).
Numbers of bins. For some data types there are additional default behaviours.
- Boolean attributes always have exactly two bins.
- Set and List attributes always have unlimited bins, allowing each tag or element its own bin.
- Date attributes: if the date "never" is present, it is always placed in its own bin.
