Title

The set title command produces a plot title that is centered at the top of the plot. set title is a special case of set label.

Syntax: 

     set title {"<title-text>"} {<xoff>}{,<yoff>} {"<font>,{<size>}"}
     show title

Specifying constants <xoff> or <yoff> as optional offsets for the title will move the title <xoff> or <yoff> character screen coordinates (not graph coordinates). 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.

<font> is used to specify the font with which the title is to be written; the units of the font <size> depend upon which terminal is used.

set title with no parameters clears the title.
