Description:

KMatplot is a gnuplot-like tool for plotting data sets in either two
or three dimensions. It can plot many ordinary types of 2d plots,
including pixmaps and contours, and 3d surfaces. It offers a full
WYSIWYG mode with multiple objects on a single page. See the
screenshot section for more details.

As opposite to Gnuplot, KMatplot has no scripting language but it is
more clickable, so easier to use for unexperienced users. It can be
used instead of Gnuplot with Octave and Scilab - there are new dll
functions installed in those packages, which communicate with KMatplot
through an Unix socket. Those functions are named 'kplot', 'kimage',
kmesh',... and are similar to those found in Octave by default.
