Filled Boxes

This wanted feature was not be included in the v3.6betas and the v3.7 release. Barchart workarounds might help to produce fancy barcharts and more.

Piecharts

Another wanted feature. Sorry, gnuplot is not the right program to ask for piecharts for different reasons. It should be done with other software in my opinion. I have created an example program for piechart creation with GNU plotutils(oneway) which might be useful if you really need piecharts. (Note: the plotutils library is mainly useful on Unix-like systems so far.)

Colorfilled contour plots

Petr Mikulik wrote an experimental pm3d splot mode(leave). This adds the possibility to draw colour/gray maps and surfaces, even for non-gridded data. Pm3d works on all platforms for a subset of gnuplot output terminals. It was distributed as a patch to gnuplot 3.7 and is now incorporated into the development versions. So check Petr's page for update. (I haven't tried pm3d yet, but it looks very promising.)

Frontends

The regular gnuplot version already comes with certain GUI features depending on the platform. Other front-ends might be out there.

Short Description

Gnuplot is a command-driven interactive function plotting program. It can be used to plot functions and data points in both two- and three- dimensional plots in many different formats, and will accommodate many of the needs of today's scientists for graphic data representation. Gnuplot is Free Software(leave) coming with its own license. Adapted from: 1.1 What is gnuplot?, Gnuplot FAQ for 3.7(leave)

Alternatives

If gnuplot is not what you want, you can consider Grace(leave) (needs X11) or check Scientific Data Processing & Visualization Apps for Linux(leave)

History

v4.0 five years after 3.7

Gnuplot v4.0 was officiall released on April, the 16th 2004. Here is ann archived copy of the gnuplot-4_0.annoucement.txt .

Domain and development 2000/2001

v3.7 came after five years

Gnuplot v3.7 was official released on 14th of January 1999. It corresponded to the lastest 3.6beta version: pl349. It was the first official gnuplot release after more as 5 years of development. See the gnuplot3.7.annoucement.txt for yourself. Note: The official websites mentioned there were suffering from pop-up ads. :-( The new official FTP site: ftp://ftp.gnuplot.vt.edu/pub/gnuplot/(leave) Look around as you may find a new FAQ, contributions and new beta versions there.

v3.6

For a long time there was no official gnuplot release and I recommended the use of one of the 3.6beta versions, which were quite stable. You could get it via ftp at cmpc1.phys.soton.ac.uk (leave). The latest source usually was at cmpc1.phys.soton.ac.uk/pub/ (leave). Binaries for various platforms sometimes could be found in cmpc1.phys.soton.ac.uk/incoming/ (leave) You still might be find some versions there. «Bernhard`s Homepage Internal | Infoservice last modified: November 2004
