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`.``
