Syntax:
set title {"<title-text>"} {<xoff>}{,<yoff>} show title
Specifying constants <xoff> or <yoff> as optional offsets for the title will move the title <xoff> or <yoff> character screen co-ordinates (not plot co-ordinates). For example,
set title ,-1
will change only the y offset of the title, moving the title down by roughly the height of one character.
set title with no parameters clears the title.
See set syntax for details about the processing of backslash sequences and the distinction between single- and double-quotes.
