Origin Ver. and Service Release (Select Help-->About Origin): Origin 9 SR1
Operating System: Windows

Dear all,
I wish to know if it is possible with Origin 9 to fit multiple Gaussian peaks on several data column simultaneously and with shared position and width from one column to another.
Sincerely,

Hi Qspecies,

Maybe the following tutorial helps, but unfortunately it requires OriginPro 2016:

Hi Hideo,
Thank you for the reply however this is not completely what I want. I know how to use this procedure for fitting several peaks on a spectrum. For that fine but I want to fit several spectra in the same time with the same peaks sharing position and width.
This seems to be impossible with Origin 9

We support global fit of multiple dataset with same function and have parameter sharing.

You can watch this Tutorial to see how it works.
