KMatplot 0.3 prerelease

Source package is available at:
http://kmatplot.sourceforge.net/kmatplot-0.3.tar.gz

RPM packages for RedHat 7.1 / KDE2.1.1 are available at:
http://kmatplot.sourceforge.net/kmatplot-0.3-1.i386.rpm

There is no reference to the above packages on the Web site !

Change log:
- cut/copy/paste,
- undo/redo,
- group/ungroup objects,
- multiple pages,
- arbitrary number of axes per graph,
- formulas ( still under development ),
- surfaces and contours can display non-gridded data ( using Delunay 
triangulation ),
- colored area under surface, v-gradient, plotting 4d data ( still under 
development ),
- XY plots - stairs,
- custom tics values,
- fast selecting of graph elements by middle button click,
- general data storing policy - vectors are stored as columns,
- many bug fixes.

Notes:

1.
File format has been modified. You can lose some attributes of saved graphs.

2.
Data storing policy has changed.

XY plots:
Vectors are stored as columns, not rows.
You have to transpose all vectors after you read an old file
( Edit/Transpose option in the worksheet main menu ).


3.
Data storing policy has changed.

Image,contours,surfaces:
Data channel ordering has changed.

It was:
        0.Data
        1.Column index vector
        2.Row index vector

It is:
        0.Column index vector
        1.Row index vector
        2.Data

All you data will be read as Column index vector, you will have to set it as 
Data again. Use Edit/Cut, Edit/Pase options from the worksheet main menu.

4.
You can safely configure KMatplot with an option: --without-gl, it does not 
require OpenGL anymore.

5.
Installing and running in a non-default directory 
( example dir: /home/kamil/kmatplot )

./configure --prefix=/home/kamil/kmatplot

make install

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/kamil/kmatplot/lib

env KDEDIR=/home/kamil/kmatplot /home/kamil/kmatplot/bin/kmatplot

6.
KMatplot will crash immediately after start if it doesn't find its resource 
files, so it is important to provide a correct KDEDIR shell variable if the 
program is not installed in the default directory. Build system fails to 
detect a default KDE path on some distributions, especially on Suse. You can 
pass KDE path to configure using --prefix option:
./configure --prefix=/opt/kde2
