Gnuplot format manual#
See the printed manual or the on-line help for details on specific commands. Please report bugs using the project bug tracker on SourceForge. Starting with gnuplot version 3.8, the project source is cooperatively maintained on SourceForge by a large number of contributors. Original authors: Thomas Williams and Colin Kelley. The default name of the logfile output by the "fit" command. It may contain any legal gnuplot commands, but typically they are limited to setting the preferred terminal and line types and defining frequently-used functions or variables. The standard location of this file expected by the program is reported by the "show loadpath" command.gnuplotĪfter loading the system-wide initialization file, if any, Gnuplot looks for a private initialization file in the HOME directory. When gnuplot is run, it first looks for a system-wide initialization file named gnuplotrc. Use this variable to test the postscript terminal with custom prologue files. Depending on the build process, gnuplot contains either a builtin copy of those files or simply a default hardcoded path.
Gnuplot format driver#
Used by the postscript driver to locate external prologue files. The contents of GNUPLOT_FONTPATH are appended to the "fontpath" variable, but not saved with the "save" and "save set" commands. The format is the same as for GNUPLOT_LIB. The font search path used by the postscript terminal.
Gnuplot format drivers#
The default font for the terminal drivers that access TrueType fonts via the gd library. This variable gives the font search path for these drivers. Several gnuplot terminal drivers access TrueType fonts via the gd library. The contents of GNUPLOT_LIB are appended to the "loadpath" variable, but not saved with the "save" and "save set" commands. The variable may contain a single directory name, or a list of directories separated by ':'. GNUPLOT_LIBĪdditional search directories for data and command files. The name of the logfile maintained by fit. Specifies a gnuplot command to be executed when a fit is interrupted-see "help fit". The program used for the "shell" command. The pathname of the HELP file (gnuplot.gih). gnuplot start-up files and, of course, by later explicit "set terminal" commands. This can be overridden by the gnuplotrc or.
The name of the terminal type to be used by default. EnvironmentĪ number of shell environment variables are understood by gnuplot. These options have no effect on other terminal types. For additional X options specific to gnuplot, type help x11 on the gnuplot command line. See the X(1) man page for a description of common options. h, -help print summary of usage -V, -version show current version X11 Optionsįor terminal type x11, gnuplot accepts the standard X Toolkit options and resources such as geometry, font, and background. s, -slow wait for slow font initialization rather than continuing with an error. e "command list" executes the requested commands before loading the next input file. Do not read from gnuplotrc or ~/.gnuplot on entry. , load script using gnuplot's "call" mechanism and pass it the remainder of the command line as arguments -d, -default-settings settings.
Gnuplot format windows#
Options -p, -persist lets plot windows survive after main gnuplot program exits. Support for a huge variety of output devices and file formats. Shell escapes and command line substitution. There is an on-line demo collection atĢD and 3D plots with mouse-controlled zooming, rotation, and hypertext. Many presentation styles for plotting user data from files, including surface-fitting, error bars, boxplots, histograms, heat maps, and simple manipulation of image data. Just the real part is plotted by default, but functions like imag() and abs() and arg() are available to override this. Plots any number of functions, built up of C operators, C math library functions, and some things C doesn't have like **, sgn(), etc.Īll computations performed in the complex domain. If no files are given, gnuplot prompts for interactive commands. If file names are given on the command line, gnuplot loads and executes each file in the order specified, and exits after the last file is processed. Gnuplot is a command-driven interactive plotting program.
