TextFile

This option specifies the region of the plot which will be displayed. 

Ranges may be provided on the 'plot' command line as synonyms for
the 'set xrange' and 'set yrange' commands.

Syntax:
        [{dummy-var =} {xmin : xmax}] { [{ymin : ymax}] }

Where dummy-var is the independent variable (the default is 'x',
but this may be changed with the 'set dummy' command) and the min
and max terms can be expressions or constants. 

Both the min and max terms are optional.  The ':' is also optional
if neither a min nor a max term is specified.  This allows '[]' to
be used as a null range specification. 

Specifying a Y range turns autoscaling OFF.


Examples:

This uses current ranges:
        plot cos(x)

This sets the xrange only:
        plot [-10:30] sin(pi*x)/(pi*x)

This is the same, but uses t as the dummy-variable:
        plot [t = -10 :30]  sin(pi*t)/(pi*t)

This sets both the x and yranges:
        plot [-pi:pi] [-3:3]  tan(x), 1/x

This sets only the yrange:
        plot [] [-2:sin(5)*-8] sin(x)**besj0(x)

This sets xmax and ymin only:
        plot [:200] [-pi:]  exp(sin(x))
