Title

A title of each plot appears in the key. By default the title is the function or file name as it appears on the plot command line. The title can be changed by using the title option. This option should precede any with option.

Syntax: 

        title "<title>"

where <title> is the new title of the plot and must be enclosed in quotes. The quotes will not be shown in the key.

Examples:

This plots y=x with the title 'x': 

        plot x

This plots the ``glass.dat'' file with the title 'surface of revolution': 

        splot "glass.dat" title 'surface of revolution'

This plots x squared with title ``x^2'' and ``data.1'' with title 'measured data': 

        plot x**2 title "x^2", "data.1" t 'measured data'
