i wrote the following LabTalk script in order to do a voigt fit:

nlsf.init()
nlsf.func$=Voigt;
nlsf.fitcolnum = 1
nlsf.fitWksName$=data1_A1;
nlsf.p1=0;
nlsf.p2=36;
nlsf.p3=10000;
nlsf.p4=10;
nlsf.p5=10;
nlsf.iterate(100);

but i have a problem: the script only works when i plot the data base before. i want it to fit directly from the data base.
how can i do that?

Take a look at this Fitting with Script example and then let me know if you still have questions.

Hello Idoidoido:

The following Labtalk script will fit to either a dataset in a worksheet or a curve in a plot depending on whether a worksheet or graph is active before you execute the script.

// Fit to Nth Column in Active Worksheet, or
// Fit to Nth Curve in Active Graph Window
n=3; //N is Nth Col or Curve of Active Window
nlsf.init();
nlsf.func$=Voigt;
nlsf.fitcolnum = 1;
nlsf.fitdata$=%(n,@D); //Fit Nth Column or Curve
nlsf.p1=0;
nlsf.p2=36;
nlsf.p3=10000;
nlsf.p4=10;
nlsf.p5=10;
nlsf.iterate(100);
nlsf.end();
rescale;
// The End (fsz)
