KMatplot is a gnuplot-like tool for plotting data sets in either two or three dimensions.
It can plot many 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 is very 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.

Lets summarize all features:
- 2D, 3D, pixmap and contour plots,
- full page or single axes view mode,
- easy, interactive label placing and editing,
- zoom and locate tools,
- XML-based native file format,
- imports Matlab MAT1.0 and space separated ASCII data sets,
- exports data in ASCII format,
- optional OpenGL support for 3d plots ( although all functionality is available without it ),
- Postscript printing,
- Octave and Scilab support,
- can plot large datasets,
- worksheet,
- formulas
There is also a widget library, but currently it isn't distributed as a separate library.

Notes:
-
Installing and running in a non-default directory
( example dir: ~/kmatplot )
- ./configure --prefix=~/kmatplot
- make install
- export LDLP=$LDLP:~/kmatplot/lib (LDLP stands for LD_LIBRARY_PATH)
- env KDEDIR=~/kmatplot ~/kmatplot/bin/kmatplot
-
KMatplot will crash immediately after start if it doesn't find its resource
files, so it is important to provide a correct KDEDIR (KDEDIRS on Suse) shell
variable if the program is not installed in the default directory. Build system
fails to detect a default KDE path sometimes, especially on Suse. You can
pass KDE path to configure using --prefix option:
./configure --prefix=/opt/kde2
-
If your gcc takes to much system resources when compilling projectxml.cpp file, you
will have to stop compilation ( CTRL+C ), turn off all optimization flags, and start it again
( see below commands ):
export CXXFLAGS="-O0"
./configure
make
-
SUSE 7.3 fails to compile the program returning error:
./aclocal.m4:2508: error: m4_defn: undefined macro: _m4_divert_diversion
Look at offical Suse explanation.
You will have to downgrade autoconf using old SUSE 7.2 packages.
-
Tips for Debian compilation:
Make sure you have the following packages:
kdebase-dev
libqt-gl-dev
octave2.1 (and associates)
configure with:
"./configure --prefix=/usr --with-qgl-extension=/usr/lib/libqt-gl.a"
The --prefix=/usr is there so that kmatplot goes in with all the other KDE
apps and doesn't have any problems finding it's resources.
