gnuplot homepage Overview & Contact Data

The gnuplot homepage is the main site for a portable, command-line driven graphing utility used by scientists, students, engineers, and developers who need to visualize mathematical functions, experimental data, and statistical results. The project supports Linux, Windows, macOS, OS/2, VMS, and other platforms, making it a practical plotting tool for desktop environments, servers, and reproducible workflows. The source code is freely distributed, and the site provides download links, user manuals, demo galleries, bug tracker access, tutorials, external resources, and a Git repository for contributors. Gnuplot is notable for its long history and active development since 1986. The current stable release is version 6.0, with a previous stable 5.4 line also documented, while a development version is available for advanced users. The site organizes release notes, PDF manuals in English and Japanese, demo galleries, and online HTML documentation, helping users compare versions and find the right manual for their installation. This structure is especially useful for people embedding gnuplot in scripts, generating publication figures, or maintaining older applications that depend on a specific release. The homepage also highlights gnuplot’s broad output support, including interactive screen display through Qt, wxWidgets, X11, Windows, and OS/2 interfaces, as well as direct file output to PostScript, EPS, PDF, PNG, GIF, JPEG, LaTeX, Metafont, EMF, and SVG. Web-oriented formats such as HTML5 and SVG support mouseable displays, which makes the tool useful for dashboards, technical reports, and web-based visualization. Because third-party applications such as Octave can use gnuplot as a plotting engine, the site serves both general users and software developers who need a dependable, cross-platform graphics backend.
