Hi,
The simplest way is to use a Quick Peaks Gadget, first make a plot of the curve you want to fit and then go to menu Gadgets: Quick Peaks to open dialog.
Options need to set:
1. In Baseline tab, select "Min&Max" as Mode to find positive peaks using min Y and negative peaks using max Y.
2. In Find Peak tab, select (X,Y) of Peaks as "Label" drop-down list under "Peak Display:Peak Label" node.
3. Click "OK" to apply the settings.
Then, you will see the results as shown below:
If you want to further control the fitting process, you can use Peak Analyzer feature in Origin from this tutorial:
