How often do you use Nonlinear Fit?

Nonlinear is a great platform to fit curves in JMP. But unfortunately, it's lacking some functions - how can I steal them from the other platforms and use them in Nonlinear?

- axis transforms - like in Graph Builder or Degradation:

- local data filter - like in other platforms

- easy way to define the fit function - like in Degradation

- the Group option in Fit Curve is great, there is a nice overview of the fit parameters:

and all fits can be compared within the same plot:

Degradation is a great platform to fit curves. But unfortunately, it's lacking some functions - how can I steal them from the other platforms and use them in Degradation?

- constraints - like in Nonlinear
- the Group option in Fit Curve is great, there is a nice 2D overview of the fit parameters

Fit Curves is a great platform to fit curves. But unfortunately, it's lacking some functions - how can I steal them from the other platforms and use them in Fit Curves?

- axis transforms - like in Graph Builder or Degradation

- a way to define a custom fit function - like in Nonlinear and Degradation

- constraints, like in Nonlinear

- a data filter (one that filters the data and doesn't destroy the report)

Graph Builder is an amazing plotting tool, but it's also a great platform to fit curves. But unfortunately, it's lacking some functions - how can I steal them from the other platforms and use them in Fit Curves?

- a way to define a custom fit function - like in Nonlinear and Degradation

- constraints, like in Nonlinear

- and perhaps: a nice way to get the fit parameters

do you know:
Is Degradation a wrapper for Nonlinear?
Is there a hidden menu to set and forward the constraints?

another topic: speed
... which will require more than just a few lines of code.
