Repeating curve fitting

[Tomm]

Hi all,

I'd like to do curve fitting (Gaussian) following portion of data sequentially.
X0 column or X1 fits Y0 or Y1, respectively.

Using 'Analyze > tool > curve fitting', I need to copy and paste each data set (X0 and Y0 etc.) and press 'fit' in each time. But, I felt this is labor intensive.
Ideally, I think following steps are desirable.
1) copy and paste or select whole data set (X0, Y0,....Xn,Yn)
2) select a formula (Gaussian etc.)
3) fit
4) show log (parameter, R^2)

How should I do? Actually, I can't make 'macro' or something.
Thank you for any help you can provide.

Hi Tom the built-in functions for fit are listed at this page (look for "Fit Functions"), but you need to open the editor and put this instruction in a macro:

Thanks, Rocco. I anxious for making macro myself, however, i cannot do that now. Could anybody help me?

Hi Rocco. I could make a Macro using "Fit functions" as you told and more functions. Thank you very much.
