YVIRTUALMIN

Syntax: SET YVIRTUALMIN n
GET YVIRTUALMIN { n }
Default: YVIRTUALMIN = YMIN

YVIRTUALMIN controls the virtual minimum value for the y-axis.

If YVIRTUALMIN is less than YMIN, the actual y-axis minimum value will be YMIN, while the large, numbered, tic marks will begin at YVIRTUALMIN, which may be 'off the end' of the y-axis.

YVIRTUALMIN is always set to YMIN whenever YMIN is set, so you must set YVIRTUALMIN after YMIN.
