LabPlot

This release added native export to SVG, EPS, and
other graphic formats. Ternary and polar plots are
now supported. (De)convolution and interpolation
were added to the analysis functions. Zooming, error
bar plotting, and annotate values can now be used.
Additional plot symbols and brushes were included
along with support for reading and writing netCDF,
CDF, and audio (WAV, AU, SND, AIFF) files. The graph
list dialog was improved and a new file info dialog
was added.

It is now possible to have multiple plots per
worksheet. Support for time and date formats was
added. The axes settings, surface plots, and
nonlinear fitting were improved. Pie, GRASS, and
VTK plots are now supported. The documentation was
improved, and a German handbook was added.

This release adds support for linear regression and nonlinear fitting. The fourier transform using gsl or fftw is improved. Integration, differences, and histograms are now available. Drawing objects can now be created, edited, and moved with the mouse. A Kpart for LabPlot projects is now available. Reading and writing of compressed data was added, a lot of bugfixes were made and the German translation was improved.

This release adds logarithmic axes scales and
drawing objects. Support for gsl (GNU Scientific
Library) special functions and distributions was
also added. An additional Fourier transform via
gsl is available now. Output can now be exported
to PDF, FIG, DXF, and other formats via pstoedit
and to over 100 different image formats via
ImageMagick.

The graphical user interface and the KDE integration was
much improved. It is now possible to use rich text for title
and axes label. The three dimensional plotting was also
much improved. Simple analysis functions are now
available, and the ability to configure user settings and
examples was added too.
