Package gnuplot-nogtk-4.6.0-2

Gnuplot is a portable command-line driven interactive data and function plotting utility for UNIX, IBM OS/2, MS Windows, DOS, Macintosh, VMS, Atari and many other platforms. The software is copyrighted but freely distributed (i.e., you don't have to pay for it). It was originally intended as to allow scientists and students to visualize mathematical functions and data. It does this job pretty well, but has grown to support many non-interactive uses, including web scripting and integration as a plotting engine for third- party applications like Octave. Gnuplot has been supported and under development since 1986. Gnuplot supports many types of plots in either 2D and 3D. It can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text. It also supports various specialized plot types. Gnuplot supports many different types of output: interactive screen terminals (with mouse and hotkey functionality), direct output to pen plotters or modern printers, and output to many file formats (eps, fig, jpeg, LaTeX, metafont, pbm, pdf, png, postscript, svg, ...). Gnuplot is easily extensible to include new output modes.

The bare 'gnuplot' package has most of the available options included. Use the -nox variant if you don't want X11 support at all. Use the -nogtk variant if you want X11 but not the wxWidgets terminal. Upstream's default font choice doesn't work on case-sensitive filesystems, so we set the GDFONTDIR environment variable to /Library/Fonts, and the GNUPLOT_DEFAULT_GDFONT environment variable to be "Arial". If you want a different setup, you can set these yourself in your startup files, or in your invocation of gnuplot, e.g. env GNUPLOT_DEFAULT_GDFONT="Verdana" gnuplot
