GraphiXT is a data analysis software and numerical computing environment. The original purpose of GraphiXT was to facilitate study of time dependences (i.e., kinetics) of a large number of physical quantities that are related to each other. Consequently, graphs displayed by GraphiXT are of two types: graphs of functions f(t), whose argument is time (t), and graphs of functions f(x, t), whose arguments are coordinate (x) and time (t). However, the actual meaning of function arguments is up to the user. GraphiXT.exe can be used as a stand-alone program or in conjunction with plug-ins that solve kinetic equations describing a particular physical system. Currently, there is one such plug-in, which is designed to simulate charge carrier kinetics in multi-layer systems. That plug-in consists of two files the function file CarrierFunc.dll and the parameter editor file CarrierParms.exe.

The GraphiXT software package has been developed by Andrius Poškus (Vilnius University, Faculty of Physics) as an educational tool for the graduate course "Numerical simulation of charge transport processes". It can also be used as a scientific research tool. Here are some features of GraphiXT: Operating system: Windows XP SP2 or a newer Windows version.
