Hello everyone,
I would like to find the maximum of the cumulative fit shown below. Of course I could just extract the values of the single fits, sum the three equations up, derive and set them 0 to find it, but I'm sure there is a more time efficient way.
Thank you very much!

Hi,
Would you please explain more about the operations "extract the values of the single fits, sum the three equations up, derive and set them 0 to find it"?
We think:
Once you did the peak fits, you can find the data "Cumulative Fit Peak" in the result sheet "FitPeakCurve#". Extract this column with X data and then find the highest point in this curve to get the Maximum. If needed, you can export more data points for the fitted curves(in the Result branch of Fit Peaks page) to make the maximum finding more precisely.
Please let me know if any problem.
Thanks,
Shirley
