Terminal types

Complete list of terminals

Gnuplot supports a large number of output formats. These are selected by choosing an appropriate terminal type, possibly with additional modifying options. See set terminal (p. 152).

This document may describe terminal types that are not available to you because they were not con gured or installed on your system. To see a list of terminals available on a particular gnuplot installation, type 'set terminal' with no modi ers.

Aed767

The aed512 and aed767 terminal drivers support AED graphics terminals. The two drivers di er only in their horizontal ranges, which are 512 and 768 pixels, respectively. Their vertical range is 575 pixels. There are no options for these drivers.

Aifm

NOTE: Outdated terminal, originally written for Adobe Illustrator 3.0+. Since Adobe Illustrator understands PostScript level 1 commands directly, you should use set terminal post level1 instead.

Syntax:

set terminal aifm {color|monochrome} {"<fontname>"} {<fontsize>}

Aqua

This terminal relies on AquaTerm.app for display on Mac OS X.

Syntax:

set terminal aqua {<n>} {title "<wintitle>"} {size <x> <y>} {font "<fontname>{,<fontsize>}"}

{{no}enhanced} {solid|dashed} {dl <dashlength>}}

where <n> is the number of the window to draw in (default is 0), <wintitle> is the name shown in the title bar (default "Figure <n>"), <x> <y> is the size of the plot (default is 846x594 pt = 11.75x8.25 in).

Use <fontname> to specify the font (default is "Times-Roman"), and <fontsize> to specify the font size (default is 14.0 pt).

The aqua terminal supports enhanced text mode (see enhanced (p. 23)), except for overprint. Font support is limited to the fonts available on the system. Character encoding can be selected by set encoding and currently supports iso latin 1, iso latin 2, cp1250, and UTF8 (default).

Lines can be drawn either solid or dashed, (default is solid) and the dash spacing can be modi ed by <dashlength> which is a multiplier > 0.

Be

The be terminal type is present if gnuplot is built for the beos operating system and for use with X servers. It is selected at program startup if the DISPLAY environment variable is set, if the TERM environment variable is set to xterm, or if the -display command line option is used.

Syntax:

set terminal be {reset} {<n>}

Multiple plot windows are supported: set terminal be <n> directs the output to plot window number n. If n>0, the terminal number will be appended to the window title and the icon will be labeled gplt <n>. The active window may distinguished by a change in cursor (from default to crosshair.)

Plot windows remain open even when the gnuplot driver is changed to a di erent device. A plot window can be closed by pressing the letter q while that window has input focus, or by choosing close from a window manager menu. All plot windows can be closed by specifying reset, which actually terminates the subprocess which maintains the windows (unless -persist was speci ed).

Plot windows will automatically be closed at the end of the session unless the -persist option was given.

The size or aspect ratio of a plot may be changed by resizing the gnuplot window.

Linewidths and pointsizes may be changed from within gnuplot with set linestyle.

For terminal type be, gnuplot accepts (when initialized) the standard X Toolkit options and resources such as geometry, font, and name from the command line arguments or a con guration le. See the X(1) man page (or its equivalent) for a description of such options.

A number of other gnuplot options are available for the be terminal. These may be speci ed either as command-line options when gnuplot is invoked or as resources in the con guration le ".Xdefaults". They are set upon initialization and cannot be altered during a gnuplot session.

Command-line options

In addition to the X Toolkit options, the following options may be speci ed on the command line when starting gnuplot or as resources in your ".Xdefaults" le:

The options are shown above in their command-line syntax. When entered as resources in ".Xdefaults", they require a di erent syntax.

Example:

gnuplot*gray: on

gnuplot also provides a command line option (-pointsize <v>) and a resource, gnuplot*pointsize: <v>, to control the size of points plotted with the points plotting style. The value v is a real number (greater than 0 and less than or equal to ten) used as a scaling factor for point sizes. For example, -pointsize 2 uses points twice the default size, and -pointsize 0.5 uses points half the normal size.

Monochrome options

For monochrome displays, gnuplot does not honor foreground or background colors. The default is black- on-white. -rv or gnuplot*reverseVideo: on requests white-on-black.

Color resources

For color displays, gnuplot honors the following resources (shown here with their default values) or the greyscale resources. The values may be color names as listed in the BE rgb.txt le on your system, hexadecimal RGB color speci cations (see BE documentation), or a color name followed by a comma and an intensity value from 0 to 1. For example, blue, 0.5 means a half intensity blue.

gnuplot*background: white gnuplot*textColor: black gnuplot*borderColor: black gnuplot*axisColor: black gnuplot*line1Color: red gnuplot*line2Color: green gnuplot*line3Color: blue gnuplot*line4Color: magenta gnuplot*line5Color: cyan gnuplot*line6Color: sienna gnuplot*line7Color: orange gnuplot*line8Color: coral

The command-line syntax for these is, for example,

Example:

gnuplot -background coral

Grayscale resources

When -gray is selected, gnuplot honors the following resources for grayscale or color displays (shown here with their default values). Note that the default background is black.

gnuplot*background: black gnuplot*textGray: white gnuplot*borderGray: gray50 gnuplot*axisGray: gray50 gnuplot*line1Gray: gray100 gnuplot*line2Gray: gray60 gnuplot*line3Gray: gray80 gnuplot*line4Gray: gray40 gnuplot*line5Gray: gray90 gnuplot*line6Gray: gray50 gnuplot*line7Gray: gray70 gnuplot*line8Gray: gray30

Line resources

gnuplot honors the following resources for setting the width (in pixels) of plot lines (shown here with their default values.) 0 or 1 means a minimal width line of 1 pixel width. A value of 2 or 3 may improve the appearance of some plots.

gnuplot*borderWidth: 2 gnuplot*axisWidth: 0 gnuplot*line1Width: 0 gnuplot*line2Width: 0 gnuplot*line3Width: 0 gnuplot*line4Width: 0 gnuplot*line5Width: 0 gnuplot*line6Width: 0 gnuplot*line7Width: 0 gnuplot*line8Width: 0

gnuplot honors the following resources for setting the dash style used for plotting lines. 0 means a solid line. A two-digit number jk (j and k are >= 1 and <= 9) means a dashed line with a repeated pattern of j pixels on followed by k pixels o . For example, '16' is a "dotted" line with one pixel on followed by six
