MathGL is a library for making high-quality scientific graphics under Linux and Windows, fast data plotting and handling of large data arrays, working in window and console modes, and easily embedding into other programs. It has more than 40 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 an OpenGL interface and can be used from console programs. It has functions for data handling and MGL language scripting for simplification of data plotting. It has several types of transparency and smoothed lightning, vector fonts and TeX-like formula drawing, an arbitrary curvilinear coordinate system, and many other useful things.
UDAV is a cross-platform program for data array visualization based on the MathGL library. It supports a wide spectrum of graphics, simple script language, and visual data handling and editing. It has a windowed interface for data viewing, changing, and plotting. It can execute MGL scripts, set up and rotate graphics, export to bitmap or vector (EPS or SVG) files, draw TeX-like formulas, and so on.
