#### 4.1.54 tgif

Tgif is an X11-based drawing tool—it has nothing to do with GIF.

The ‘tgif‘ driver supports different pointsizes (with pointsize), different label fonts and font sizes (e.g. ‘set label "Hallo" at x,y font "Helvetica,34"‘) 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‘, ‘linwidth 1.0‘, ‘dashed‘, ‘"Helvetica,18"‘.

The ‘solid‘ option is usually prefered 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 multiplot 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 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"
