LabPlot is a KDE application for data plotting and function analysis. It support both 2D and 3D plots and tries to emulate most of the functions supported by programs like Microcal Origin or SPSS Sigmaplot.

A versatile spreadsheet for data import and
editing was added. A better 3 dimensional plot
with rotation and colormaps is also available.
Data set operations and image manipulations are
now supported. One can now import over 80
different images formats and export directly to
PS, EPS, or PDF. The plots now use double
buffering, and LabPlot supports scripting using
QSA.
