Tgif

Legacy terminal (present only if gnuplot was configured –with-tgif). Tgif is/was an Xlib based interactive 2-D vector graphics drawing tool also capable of importing and marking up bitmap images.

The tgif driver supports a choice of font and font size and multiple graphs on the page. The proportions of the axes are not changed.

Syntax:

     set terminal tgif {portrait | landscape | default} {<[x,y]>}
                       {monochrome | color}
                       {{linewidth | lw} <LW>}
                       {solid | dashed}
                       {font "<fontname>{,<fontsize>}"}

where $<$[x,y]$>$ specifies the number of graphs in the x and y directions on the page, color enables color, linewidth scales all linewidths by $<$LW$>$, "$<$fontname$>$" is the name of a valid PostScript font, and $<$fontsize$>$ specifies the size of the PostScript font. defaults sets all options to their defaults: portrait, [1,1], color, linewidth 1.0, dashed, "Helvetica,18".

The solid option is usually preferred if lines are colored, as they often are in the editor. Hardcopy will be black-and-white, so dashed should be chosen for that.

Multiplot is implemented in two different ways.

The first multiplot implementation is the standard gnuplot multiplot feature:

     set terminal tgif
     set output "file.obj"
     set multiplot
     set origin x01,y01
     set size  xs,ys
     plot ...
          ...
     set origin x02,y02
     plot ...
     unset multiplot

See set multiplot (p. ) for further information.

The second version is the [x,y] option for the driver itself. The advantage of this implementation is that everything is scaled and placed automatically without the need for setting origins and sizes; the graphs keep their natural x/y proportions of 3/2 (or whatever is fixed by set size).

If both multiplot methods are selected, the standard method is chosen and a warning message is given.

Examples of single plots (or standard multiplot):

     set terminal tgif                  # defaults
     set terminal tgif "Times-Roman,24"
     set terminal tgif landscape
     set terminal tgif landscape solid

Examples using the built-in multiplot mechanism:

     set terminal tgif portrait [2,4]  # portrait; 2 plots in the x-
                                       # and 4 in the y-direction
     set terminal tgif [1,2]           # portrait; 1 plot in the x-
                                       # and 2 in the y-direction
     set terminal tgif landscape [3,3] # landscape; 3 plots in both
                                       # directions
