Labels can be added to any row.
Define the default features of a newly created label with the Labels options dialog:
Menu: Diagram | Label options
Any of these options can be further customized on a per-label basis.
For a consistent look, you can change the font and color of ALL existing labels in a diagram, by clicking on the "Apply font to all existing labels" button.
Labels within a row are managed through a dialog box, listing all the row's labels, and allowing you to add, edit, duplicate or delete a label. A label's tab shows the unit at which it is positioned.
When a row is deleted, all the labels that belong to it are deleted too.
To manage the labels of a row, you need to select the row first (either by clicking on its name, or by pressing the S key and navigating to the row with the Up/Down/Home/End keys). You can then edit each label with the following options:
Select whether to Show a label, its font and Background color (if not Transparent).
A label can be aligned around the center of its unit:
Offset sign follows the directions of the X/Y axis (i.e. positive horizontal offset is to the right, and positive vertical offset is downward).
Label text can include superscript and subscript portions, e.g.:
a""n"" and t..RC..
Superscript text is surrounded by a pair of quotation marks, and subscript text is surrounded by a pair of dots.
