Dear all,

Maybe this is a trivial question, but I did not find any solution on the internet: I have an x,y data with the x data having regular intervals of 1.5. I want to fit the data and then calculate a new x,y data set with x having a new regular interval of 1.0. The normal interpolate function varies x according to the change of the y values.

Thanks a lot for your help!

Best regards

Bernhard

Hi,

You can create a X column with interval of 1.0, and then use Analysis: Mathematics: Interpolate/Extrapolate Y From X to calculate Y values.


Thanks,
