Kpl

Kpl is a KDE program for two- and three-dimensional graphical presentation of data sets and functions (plotter). Multidimensional nonlinear parameter fits of functions to data sets can be performed using the Levenberg-Marquardt algorithm. General linear least square parameter fits are also possible. A D-BUS interface can be used to control Kpl by other applications and scripts.

            very efficient simple grapher
            I find this program VERY neat and easy to use
            for even naive users, yet ok for power users.
            I think that it should be included in the main stream
            KDE. It is a lot more comfortable than grace to name
            a fairly good one.
            This is what a decent spreadsheet program should
            offer instead of what's currently avalaibale (excel, OO,
            kspread...). I found only a minor bug in the print
            output (wrong char spacing) but postscript output
            are fine (good eps with correct BB). It does not
            duplicate what is available in drawing programs
            (StarDraw...) and therefore focusses on the main
            issues: link with .so libraries is very convenient and
            simple, drag and drop of plain text file is spectacular
            and just what people need most, including simple
            .csv files usable in spreadsheets.
