Gnuplot front-ends

• gnuplot mode gnuplot-mode.el for Emacs and XEmacs
• UniGNUPlot: A graphical interface to gnuplot, based on tcl/tk
• PlotDrop: A minimal frontend to gnuplot which supports dropping of data files on GNOME and KDE

Programming interfaces

• C/C++
  • C++ iostream interface by Dan Stahlke. "This interface allows gnuplot to be controlled from C++ and is designed to be the lowest hanging fruit. In other words, if you know how gnuplot works it should only take 30 seconds to learn this library." Also available using git: git clone git://gitorious.org/gnuplot-iostream/gnuplot-iostream.git
  • gnuplot interfaces in ANSI C by Nicolas Devillard
• Fortran
  • ogpf is an object based modern fortran code (fortran 2003 / 2008) to invoke gnuplot for data visualization from inside fortran codes. It is very simple and has similar interface to Matlab plot, surf, contour, meshgrid, ... functions. It also support animation.
  • Fortran95 interface
• Java
  • gnuplot classes
  • jgnuplot: Java library for interfacing with the gnuplot.
  • JavaPlot: A full Java-oriented plotting library based on gnuplot for the graphics part, implementing most gnuplot features in a java-friendly manner.
• Julia
  • Gaston
  • gnuplot.jp (gcalderone)
• Perl
  • Gnuplot.pm
• Python interfaces to gnuplot
  • Gnuplot.py

Software that uses gnuplot

• Octave, a high-level language for numerical computations. Mostly compatible with Matlab.
• Maxima, a program for symbolic computation. Here are some nice examples of gnuplot output.
• statist is a small and portable statistics program, simple to use and can be run in scripts.
• GNUPLOTXY is an interface from GAMS (Generalized Algebraic Modelling System) to gnuplot.
• gretl (Gnu Regression, Econometrics and Time-series Library) is a cross-platform software package for econometric analysis.

Web interfaces to gnuplot

• javascript version of gnuplot compiled by Emscripten and running inside your web browser. It's more like a plugin than a web service.
