If no files are given, gnuplot\nprompts for interactive commands.\n\nHere are some of its features:\n\nPlots any number of functions, built up of C operators, C math library functions, and some\nthings C doesn't have like , sgn(), etc.\n\nUser-defined constants and functions.\n\nAll computations performed in the complex domain. Just the real part is plotted by default,\nbut functions like imag() and abs() and arg() are available to override this.\n\nMany presentation styles for plotting user data from files, including surface-fitting, error\nbars, boxplots, histograms, heat maps, and simple manipulation of image data. There is an\non-line demo collection at\nhttp://gnuplot.info/demo\n\nNonlinear least-squares fitting.\n\n2D and 3D plots with mouse-controlled zooming, rotation, and hypertext.\n\nShell escapes and command line substitution.\n\nLoad and save capability.\n\nSupport for a huge variety of output devices and file formats.\n", "subsections": [] }, "OPTIONS": { "content": "", "subsections": [ { "name": "-p, --persist", "content": "", "flag": "-p", "long": "--persist" }, { "name": "-c", "content": "", "flag": "-c" }, { "name": "mainder of the command line as arguments", "content": "" }, { "name": "-d, --default", "content": "", "flag": "-d", "long": "--default" }, { "name": "-e", "content": "", "flag": "-e" }, { "name": "-s, --slow", "content": "", "flag": "-s", "long": "--slow" }, { "name": "-h, --help", "content": "", "flag": "-h", "long": "--help" }, { "name": "-V", "content": "", "flag": "-V" } ] }, "X11 OPTIONS": { "content": "For terminal type x11, gnuplot accepts the standard X Toolkit options and resources such as\ngeometry, font, and background.

This can be overridden by the\ngnuplotrc or .gnuplot start-up files and, of course, by later explicit \"set terminal\"\ncommands.\n\nGNUHELP\nThe pathname of the HELP file (gnuplot.gih).\n\nHOME The name of a directory to search for a .gnuplot file.\n\nPAGER An output filter for help messages.\n\nSHELL The program used for the \"shell\" command.\n\nFITSCRIPT\nSpecifies a gnuplot command to be executed when a fit is interrupted---see \"help fit\".\n\nFITLOG\nThe name of the logfile maintained by fit.\n\nGNUPLOTLIB\nAdditional search directories for data and command files. The variable may contain a\nsingle directory name, or a list of directories separated by ':'. The contents of GNU‐\nPLOTLIB are appended to the \"loadpath\" variable, but not saved with the \"save\" and\n\"save set\" commands.\n\nGDFONTPATH\nSeveral gnuplot terminal drivers access TrueType fonts via the gd library. This vari‐\nable gives the font search path for these drivers.\n\nGNUPLOTDEFAULTGDFONT\nThe default font for the terminal drivers that access TrueType fonts via the gd li‐\nbrary.\n\nGNUPLOTFONTPATH\nThe font search path used by the postscript terminal. The format is the same as for\nGNUPLOTLIB. The contents of GNUPLOTFONTPATH are appended to the \"fontpath\" variable,\nbut not saved with the \"save\" and \"save set\" commands.\n\nGNUPLOTPSDIR\nUsed by the postscript driver to locate external prologue files. Depending on the\nbuild process, gnuplot contains either a builtin copy of those files or simply a de‐\nfault hardcoded path. Use this variable to test the postscript terminal with custom\nprologue files.
