The right button displays amenu.2.2Minimal ExampleLet us analyze a diffraction pattern of NaCl. The middle button shows the whole dataset (like in the toolbar). In normal mode, the left button is used for zooming and the right invokes the pop-up menu.On the helper plot, selecting a horizontal range with the left button will show this range, automatically adjustingvertical range. Hopefully, a quick look at this menu and a minute or twos worthof experiments will show the potential of this plot.Conguration of the GUI (visible windows, colors, etc.) can be saved using GUI Save current cong.On the main plot, the meaning of the left and right mouse button depends on current mode. colors ofdata points) can be changed using the sidebar.One of the most useful things which can be displayed by the helper plot is the difference between the data and themodel (it is also controlled by a pop-up menu). The output windowsshows also commands corresponding to operations performed using the GUI (menu, dialogs, etc.).The main plot can display data points, model that is to be tted to the data and component functions of the model.Use the pop-up menu (click right button on the plot) to congure it.

All corrections and improvements are welcome.

It runs on Unix specieswith GTK+, on MS Windows and (with some problems) on MacOS X.If the CLI version was compiled with the GNU Readline Library, command line editing, TAB-expanding andcommand history will be available. the width of a peak can be an independentvariable, the same as the width of another peak, or can be given by complex (and general for all peaks) formula.1.2GUI vs CLIThe program comes in two versions: the GUI (Graphical User Interface) version - more comfortable for mostusers, and the CLI (Command Line Interface) version (named ctyk to differentiate).technical noteThe GUI version is written using the wxWidgets () library. The main advantage of the program is exibility- parameters of peaks can be arbitrarily bound to each other, e.g.

Although the author has a general understanding only ofexperimental methods other than powder diffraction, he would like to make it useful to as many people as possi-ble.Fitykoffersvariousnonlinearttingmethods, simplebackgroundsubtractionandothermanipulationstothedataset, easy placement of peaks and changing of peak parameters, support for analysis of series of datasets,automation of common tasks with scripts, and much more. There are also people using it to remove thebaseline from data, or to display data only.It is reportedly used in crystallography, chromatography, photoluminescence and photoelectron spectroscopy, in-frared and Raman spectroscopy,to name but a few.
