Hi,

Is there a way to fit a graph parts by parts like the above?

I would like to fit the first part/trend with one function (red curve), and fit the second trend with another function (blue curve). My ultimate goal is fit all the parts of this cyclic graph.

Thanks!

Hi,

You can use data range selector in the Nonlinear Curve Fit to select a part of the curve.



Thanks,
Amanda
