MathGL – library for scientific graphics

Main

MathGL is ...

a library for making high-quality scientific graphics under Linux and Windows;
a library for the fast data plotting and handling of large data arrays;
a library for working in window and console modes and for easy embedding into other programs;
a library with large and growing set of graphics.

At this version (1.9) MathGL has more than 35000 lines of code, more than 55 general types of graphics for 1d, 2d and 3d data arrays. It can export graphics to raster and vector (EPS or SVG) formats. It has Qt, FLTK, OpenGL interfaces and can be used even from console programs. It has functions for data handling and script MGL language for simplification of data plotting. Also it has several types of transparency and smoothed lightning, vector fonts and TeX-like symbol parsing, arbitrary curvilinear coordinate system and many over useful things. It can be used from code written on C++/C/Fortran/Python/Octave and many other languages. Finally it is platform independent and free (under GPL v.2.0 license).

Also I recomend you to look at UDAV which is WYSWYG interface of MGL script plotter.

There is a forum where you can ask a question or suggest an improvement. However the contact form is preferable for quicker answer.

Latest news

2 July 2009. New version of MathGL is released. Most interesting: improvement in EPS/SVG export, new MGL parser (arbitrary expression as argument), new plots (Traj, ContD, Radar), windows for prepared picture only (useful in Fortran), predefined curvilinear coordiantes, Flow() from a point, legend and axis ticks improve, manual colors for plots in single string, bugs correction. Add sample page for Traj, ContD, Radar plots.
15 June 2009. New version of UDAV is released. New features: new toolbutton icons, man page, saving of last used path, automatical help/data window closing.
5 June 2009. MathGL is selected as winner of Trophées du Libre competition for Science category.
31 May 2009. Add links to 3D pdf files for all of plot samples. 3D pdf (or U3D) allows you rotate, zoom, setup the plot directly in Acrobat Reader (require Adobe Acrobat Reader v.8.1 or later).
14 May 2009. MathGL is nominmated for a 2009 Community Choice Award: Best Project for Academia.
11 November 2008. Add new font files (see Download section).
