Meta Index / Home Page / Description

Source labels.

Labels can be added to the sources depending on the value of the parameter labelstyle. This parameter works in a fashion identical to ncutsortstyle (see subsection 3.4). The accompanying expression parameter is labelexpression. The usual caveat applies to labelexpression, namely that it will not yet work with an expression which contains more than a simple column name.

At present, only integer values are permitted as source labels, so if labelstyle=`expr' the column indicated in labelexpression must be an integer-valued one. In future it is intended to allow any alphanumeric column value to be used. The parameter interface for labels may at that point be expanded or modified slightly.

The colour, text size and line thickness of the source circles and labels may be specified via the parameters labelcolour, labelsize and thickness.
