Gnuplot 4.2.5

iconGnuplot 4.2.5 per Mandriva Linux 2009.1

Gnuplot is a portable command-line driven interactive data and function plotting utility for UNIX, IBM OS/2, MS Windows, DOS, Macintosh, VMS, Atari and many other platforms.





The software is copyrighted but freely distributed (i.e., you don't have to pay for it). It was originally intended as to allow scientists and students to visualize mathematical functions and data. It does this job pretty well, but has grown to support many non-interactive uses, including web scripting and integration as a plotting engine for third-party applications like Octave. Gnuplot has been supported and under development since 1986.

Gnuplot supports many types of plots in either 2D and 3D. It can draw using lines, points, boxes, contours, vector fields, surfaces, and various associated text. It also supports various specialized plot types. Demos here.

Gnuplot supports many different types of output: interactive screen terminals (with mouse and hotkey functionality), direct output to pen plotters or modern printers, and output to many file formats (eps, fig, jpeg, LaTeX, metafont, pbm, pdf, png, postscript, svg, ...). Gnuplot is easily extensible to include new output modes. Recent additions include interactive terminals based on aquaterm (OSX) and wxWidgets (multiple platforms).

We can use Gnuplot for WXMaxima program to plot 2D and 3D graphics with an interactive front-end program, or from Octave or QtOctave. We can created our own programs written in C/C++ using the gnuplot libraries, too.

With this new version we may plotting bargraphs plots, finally.

Major additions include

* Text strings can be read and manipulated as normal data
* New interactive terminal based on wxWidgets, pango and cairo
* New 2D plot styles 'histogram' 'labels' 'image' 'rgbimage'
* New 3D plot styles 'labels' 'vectors' 'image' 'rgbimage'
* User control over color definitions and color use in plots
* Improved font handling and text formatting
* New syntax to handle string variables and string functions
* Creation of animated gif sequences
* Support for UTF-8 and other multi-byte font encodings
* Japanese language documentation and internal help
