I am looking for a user interface in labview with which I can load x/y-data (e.g. ASCII), then do a nonlinear fit to a model function. I need to see the original data and the fit data and retry the fit for various start parameters. Finally I want to save the fit curve and the parameters. I am sure somebody has done something similar and before I start from scratch ... Previously I have used the program "Origin" to do that which I do not have any longer.
Sample Code is very welcome. Thank you!
