Dear Mr.Mike Buess,
Thanks a lot. I want a curve with the same area and center with other width. Now it's ok.
Best Regards,
ZMO

Running Analysis > Fit Gaussian on Graph1 in your project gives the following Results Log readout...
Gauss fit to Sheet1_B:
Chi^2/DoF 259303.21107
R^2 0.99821
Area Center Width Offset Height
-----------------------------------------
1.847E5 511.00 2.4384 352.62 60436
It sounds like you want a curve with the same Area, Center and Offset but with Width=2.0. Here's how to do that...
1. Restore Sheet1 and select column C.
2. Run Column > Set Column Values.
3. Enter the expression gauss(col(A),352.62,511,2,1.847e5).
4. Click OK.
Details about LabTalk's gauss function are here...
