) "found their project goals to be very similar" and "decided to start a close cooperation" with the aim of merging their code into a common backend, while maintaining "two frontends, one with full KDE4 integration (called LabPlot 2.x) and one with no KDE dependencies (pure Qt) for easier cross-platform use (called SciDAVis)".

Features

It is scriptable using Qt Script for Applications (QSA). 2D and 3D plots of data can be rendered in a "worksheet", either by directly reading datafiles or from a

, which LabPlot supports. It has interfaces to several libraries, including GSL for data analysis, the Qwt3d libraries for 3D plotting using OpenGL, FFTW for fast Fourier transforms and supports exporting to 80 image formats and raw PostScript. Other key features include live data plotting, support for the FITS format, for LaTeX and Rich Text labels, data masking, data picking from images, multiple plots in the same worksheet, pie charts, bar charts/ histograms,

, and others (see developers website listed below for details). The interface is translated in various languages. LabPlot uses the Qt widget set for its graphical interface. Under Linux it is integrated with the KDE desktop and has drag and drop support with KDE's applications. Since version 2.5 LabPlot is also available for Windows.
