Two- and three-dimensional graphical presentation of data sets and functions

Kpl is a program for two- and three-dimensional graphical presentation of data sets and functions.

It performs multidimensional nonlinear parameter fits of functions to data sets using the Levenberg-Marquardt algorithm; general linear least square parameter fits are also possible. Other applications and scripts can control Kpl through a D-BUS interface. All presentation settings may be saved in plot files. Both plot and data files may be chosen by command line parameters, through the File menu, or by drag and drop. The program supports automatic scaling and normalization as well as automatic parameter fits. Presentation settings can be changed using the Edit menu. Additional data sets and functions can be displayed in the either the same or a different data window.
