PLplot is a scientific plotting package. It is relatively small, portable, freely distributable, and is rich enough to satisfy most users.
It has a wide range of plot types including line (linear, log), contour, 3D, fill, and almost 1000 characters (including Greek and mathematical) in its extended font set. The package is designed to make it easy to quickly get graphical output; only a handful of function calls is typically required.
PLplot can also be used interactively by interpreted languages such as Octave, Python, Perl and Tcl.
For more advanced use, virtually all aspects of plotting are configurable. The PLplot library is written in C, enabling it to run on many platforms practically without modification.
Key Features

- Language bindings:
- Ada.
- C/C++.
- D.
- Fortran 77/90.
- Java.
- Lisp.
- Lua.
- OCaml.
- Octave.
- Perl/PDL.
- Python.
- Tcl/Tk.
- Output file formats:
- CGM, GIF, JPEG, LaTeX, PBM, PDF, PNG, PostScript, SVG, Xfig.
- Supports a number of interactive platforms
- GDI, Gtk+, PyQt, Qt, Tcl/Tk, wxWidgets, and X.
- Any language that is supported by Unicode and installed system fonts can be used to label plots.
- Cross-platform support:
- Linux, Mac OS X, and other Unices.
- MSVC IDE on the Microsoft version of Windows (Windows 2000 and later).
- Cygwin on the Microsoft version of Windows.
- MinGW-w64/MSYS2 on the Microsoft version of Windows.
