Greetings!

I performed a successful Nonlinear Surface Fit and found surface equation coefficients.

Is there a way to use the found model in LT/Python scripts, for example in Set Column Values dialog?

Thank you.

In the Surface Fit dialog, Under Settings tab, there is the Find Z option allowing you to calculate z values using the fitted model.

Dear James,

Yes it does.
However what if I want to paste the equation with the coefficients to a column formula? Currently I do tedious copy and paste coefficient values from the report sheet.

Hi Andrey,

You can change the equation to show value instead of name https://www.originlab.com/doc/Quick-Help/add-equations-to-graph so that it's easier to copy it to formula.



Thanks, Snow

I want to suggest to implement "Save the Model to User Formula" feature.

On top of the dialog, there is Dialog theme. U can choose to save current settings as Default. Then in the future, it will use such settings.

Thanks, Snow

Thank you for suggesting.
However, my trend is to be somehow independent from the UI.
