Stack Field Properties
You can set the following properties for stack fields:
Orientation
Specifies whether the field is to be displayed vertically or horizontally
Default Child Gravity
Selects the position of each simple field relative to its cell in a stack field. Depending on the Orientation setting, there are either three vertical options or three horizontal options.
Child Margin
Sets the distance (in 1000ths of an inch) between the individual stack field components and the Left, Right, Top, or Bottom boundary of the stack field
Rotation
Defines the desired rotation in degrees. This setting overrides any child field setting. Changes to rotation appear only after the report is run.
