LabPlot is a KDE application for data plotting and function analysis.

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

Here are some key features of "LabPlot":

Versatile data and function plotting

· flexible data reading/writing in different formats (including cdf, netcdf, audio, binary, images)
· reading of images (over 80 image formats) and compressed data
· extensive parser for creating 2d, 3d functions
· support for all GNU Scientific Library (GSL) functions and constants
· creating 2d, 3d, surface, polar, ternary, and pie plots from function and data files
· basic support for GRASS plots
· multiple plots per worksheet
· data set operations
· speed mode for large data sets and data mode for inspecting data points

Easy editing of plots

· clone graphs and delete/clone plots
· versatile spreadsheet for data manipulation
· double click in plot to open detailed dialogs for all settings
· every object can be dragged by mouse
· online scaling and shifting of plots
· evaluating expressions and direct editing of data
· data statistics information
· drawing objects editing by mouse
· free or pan zooming, masking of data points and marker

Analysis of data and functions

· average, smooth and prune data
· compress, periodical and seasonal analysis
· peak find
· interpolation (splines, etc.)
· differences
· integration
· histogram
· regression (up to 10th order)
· non-linear fit (also any user defined function with up to 9 parameter)
· fourier transform
· (de)convolution
· image manipulation

LabPlot project files

· support for different worksheets and spreadsheets using MDI
· save and open all worksheets and spreadsheet in a project file (*.lpl)
· editable project information
· export worksheets as image, ps, svg, eps, pdf and many more formats (using pstoedit or ImageMagick)
· many example project files

KDE look and feel

· configure default value for plot style and symbols
· print and embedded print preview
· drag and drop support
· KPart for LabPlot projects
· KDE handbook (english and german)
· simple scripting using Qt Script for Applications (QSA)

What's New in This Release:

· fixed crash in export dialog (cdf,hdf5 items)
· import data files without extension (ImportDialog.cc)
· fixed crash when opening file (init_smg_before_opening_files.patch)
· fixed crash in function dialog (Label handling). Thanks to Petr
· fixed crash in add graph dialog
