Libiap is a set of Gnuplot (>=4.2) scripts to provide a simple library to handle mouse input in Gnuplot. So far interactive fitting of a sum of several Lorentzian curves to some data has been implemented. But it can be easily adopted to fit e.g. Gaussians, exponential decay, etc.

Interactive fitting is fitting a set of data by supplying the initial guess values just by clicking on the plot. You also can use libiap for completely different tasks in your own scripts. Just Have a look at the demonstration program of libiap…
