Projects

gnuplot

gnuplot plots 2d and 3d graphs, from a data file or with a formula. It has an interactive mode with online help, or it can be used non-interactively. gnuplot does function fitting to data sets, and it does output to many terminals, among which are PostScript, X11 display, PNG, and GIF (via the old gd library).

QtOctave

QtOctave is a front-end for Octave. Octave is a high-level language for numerical computations, like Matlab.

KmPlot

claimed by KDE

KmPlot is a mathematical function plotter. It has a powerful parser built in. You can plot different functions simultaneously and combine their function terms to build new functions. KmPlot supports functions with parameters and functions in polar coordinates. Several grid modes are possible. Plots ... [More] may be printed with high precision in correct scale. Features * powerful mathematical parser * precise metric printing * different plot types (functions, parametric, polar) * highly configurable visual settings (plot line, axes, grid) * export to bitmap format (BMP and PNG) and scalable vector graphics (SVG) * save/load complete session in readable xml format * trace mode: cross hair following plot, coordinates shown in the status bar support zooming and more.

Mathomatic

Mathomatic is a portable, general purpose CAS (Computer Algebra System) written entirely in C. This is a console mode application that does symbolic math and quick calculations. It compiles and runs under any operating system with a C compiler. There are no dependencies other than the standard C ... [More] libraries. Mathomatic has been under development since 1986 and now stands at 20,000 lines of code (including comments). [Less]

PLplot

PLplot is a library of functions that are useful for making scientific plots. PLplot can be used from within compiled languages such as Ada, C, C++, FORTRAN and Java, and interactively from interpreted languages such as Octave, Python, Perl and Tcl. The PLplot library can be used to create ... [More] standard x-y plots, semilog plots, log-log plots, contour plots, 3D surface plots, mesh plots, bar charts and pie charts. Multiple graphs (of the same or different sizes) may be placed on a single page with multiple lines in each graph. A variety of output file devices such as Postscript, png, jpeg and others, as well as interactive devices such as xwin, tk, xterm and Tektronics devices are supported. [Less]

KAlgebra

claimed by KDE

KAlgebra is a calculator with symbolic and analysis features that lets you plot 2D and 3D functions as well as to easily calculate mathematical expressions.

Scirenderer

Java rendering library based on JOGL This Java API allows 2-D or 3-D plotting from simple 2-D graph to complex scenes. . While this library has been developed in the context of Scilab, it can be used in any context.

nanoplot

A minimalistic data analysis application

Crispy Plotter

Crispy Plotter is a function graph plotter for mathematical functions, featuring high drawing speed and an intuitive interface that is fun to use.

AstroPlot

AstroPlot is a small, fast and free tool for visualizing 2D data, slightly inclined towards usage in astronomy. With AstroPlot you can: plot any number of data-files and functions, move around your data by zooming and panning, decorate your plots using various colors, fonts and different drawing ... [More] styles, export your plot as a picture or print it, and much more! Current version is 1.0.1, released on April 9 2008 [Less]
