GNUPlot Manual

114 gnuplot 4.0 36 SET-SHOW
36.59.28 Grass
The grass terminal driver gives gnuplot capabilities to users of the GRASS geographic information
system. Contact grassp-list@moon.cecer.army.mil for more information. Pages are written to the current
frame of the GRASS Graphics Window. There are no options.
36.59.29 Hercules
These drivers supports PC monitors with autodetected graphics boards. They can be used only when
compiled with Zortech C/C++. None have options.
36.59.30 Hp2623a
The hp2623a terminal driver supports the Hewlett Packard HP2623A. It has no options.
36.59.31 Hp2648
The hp2648 terminal driver supports the Hewlett Packard HP2647 and HP2648. It has no options.
36.59.32 Hp500c
The hp500c terminal driver supports the Hewlett Packard HP DeskJet 500c. It has options for resolution
and compression.
Syntax:
set terminal hp500c {} {}
where res can be 75, 100, 150 or 300 dots per inch and comp can be "rle", or "tiff". Any other inputs are
replaced by the defaults, which are 75 dpi and no compression. Rasterization at the higher resolutions
may require a large amount of memory.
36.59.33 Hpgl
The hpgl driver produces HPGL output for devices like the HP7475A plotter. There are two options
which can be set: the number of pens and eject, which tells the plotter to eject a page when done. The
default is to use 6 pens and not to eject the page when done.
The international character sets ISO-8859-1 and CP850 are recognized via set encoding iso 8859 1
or set encoding cp850 (see set encoding (p. 65) for details).
Syntax:
set terminal hpgl {} {eject}
The selection
set terminal hpgl 8 eject
is equivalent to the previous hp7550 terminal, and the selection
set terminal hpgl 4
is equivalent to the previous hp7580b terminal.
The pcl5 driver supports plotters such as the Hewlett-Packard Designjet 750C, the Hewlett-Packard
Laserjet III, and the Hewlett-Packard Laserjet IV. It actually uses HPGL-2, but there is a name conflict
among the terminal devices. It has several options which must be specified in the order indicated below:
Syntax:
set terminal pcl5 {mode } {}
{{color {}} | monochrome} {solid | dashed}
{font } {size } {pspoints | nopspoints}
