Hi,

Im a trying to make a simultaneous fit of several data sets and for some reason I only get one fit curve out corresponding to the first in the list. It seems it actually performs the joint fit (speed) but I am not able to see the single curve before I press "Done" and I dont get any other than that single fit curve.

I have to say that Origin is now les and less transparent with the newer versions that very simple things tend to be less and less convenient. I had no problems to do these things in earlier versions.

Please advise

Origin Ver. and Service Release (Select Help-->About Origin): 9.1

Operating System: Win 9 /MAC

Hi,

Please check if you add all datasets as Input Data in Data Selection page of Settings tab in NLFit dialog, and then check if you select Independent Fit in Multi-Data Fit Mode item.

FYI, we have an app can be used to fit a large number of datasets, the Sequential Fit app:

If you are interested, you can download a free demo to try this app:
