Origin Ver. and Service Release (Select Help-->About Origin): 2017
Operating System:WIn 10
Dear friends,
I want to do a fit on a part of the curve, for example: one peak of the whole curve, but I want to replace the old data of the original part with the new fitted data.

Thanks much

Hi,

With the nonlinear fit dialog box open:
Select Data Selection under the Settings Tab
Under Range -> you can select your range from your worksheet
Or under the Rows tab -> select By Row or By X i.e. range from x = 5 to x =10 on your graph.

More information:

Thanks
