Origin Ver.8 and Service Release (Select Help-->About Origin):

How to get the details of a Distribution curve in my histogram like its fitting equation and the values of the curve?
Besides, the distribution curve in my histogram seems strange that its FWFH is larger than data distribution. Is this because of the Gaussian fitting equation?

Hi,

In Origin 2017 SR0, you can export the fitting results to the Bin worksheet by the Bin Worksheet options,

For the distribution curve doesn't fit your histogram, I think it is because there are some outliers(nearby X=60) which are also considered in the distribution fitting.

Our 2017 SR0 demo version can be downloaded here,

Please have a try. Any problem, please let me know.

Thanks,
Shirley
