monochrome

Syntax:

     set monochrome {linetype N <linetype properties>}

The set monochrome command selects an alternative set of linetypes that differ by dot/dash pattern or line width rather than by color. This command replaces the monochrome option offered by certain terminal types in earlier versions of gnuplot. For backward compatibility these terminal types now implicitly invoke "set monochrome" if their own "mono" option is present. For example,

     set terminal pdf mono

is equivalent to

     set terminal pdf
     set mono

Selecting monochrome mode does not prevent you from explicitly drawing lines using RGB or palette colors, but see also set palette gray. Six monochrome linetypes are defined by default. You can change their properties or add additional monochrome linetypes by using the full form of the command. Changes made to the monochrome linetypes do not affect the color linetypes and vice versa. To restore the usual set of color linetypes, use either unset monochrome or set color.
