3.1.0.26 Gnugraph(GNU plotutils)

The `gnugraph` driver produces device-independent output in the GNU plot graphics language. The default size of the PostScript results generated by "plot2ps" is 5 x 3 inches; this can be increased up to about 8.25 x 8.25 by size.

Syntax:

      set terminal gnugraph {"<fontname>"} {<fontsize>}
                            {type <pt>} {size "<size>"}

which defaults to 10-point "Courier".

For `type`, the following options are accepted: `X`, `pnm`, `gif`, `ai`, `ps`, `cgm`, `fig`, `pcl5`, `hpgl`, `tek`, and `meta` (default). The size option (default is a4) is passed straight through to plotutils, it's the user's responsibility to provide correct values. Details can be found in the plotutils documentation.

Examples:

      set terminal gnugraph type hpgl size "a4"
      set terminal gnugraph size "a4,xoffset=-5mm,yoffset=2.0cm" type pnm

There is a non-GNU version of the `gnugraph` driver which cannot be compiled unless this version is left out."
