Knowing the coordinates of the experimental points affected by measurement errors, the coefficients
ac and bc of the regression line are determined using the Linear Fit.vi function in the menu
Mathematics / Fitting.
In addition to the values of the two coefficients, the Linear Fit.vi function generates at the Best Linear output
Fit the values of the Y '' coordinates of the points on the regression line and having the same
X coordinates as the experimental points.
The string of numeric values Y '' is the one used for plotting the third graph.
How can i do that? Thank you!

You mean something like this?

I mean, yeah, something like that, but now i can't find the calculated a and b and the regression line does not appear on the graph.

Thank you for your time, I solved the problem.

When you have solved a problem it is polite to share your solution for the benefit of others who may have the same problem in the future.

There are no "strings" anywhere. Your descriptions makes about as much sense as your code. I took the liberty to do some alternative interpretations. 😉

This also makes no sense at all. Your linear fit is done on two y-values and ten x-values. The inputs need to have the same size.

Are you sure? Please let us give a chance to check it. Also, next time please use a more useful subject line. Since this is the LabVIEW forum, every single discussion is about LabVIEW, no need to repeat that in the title. Something like "Simulation of a linear fit" would have been more useful.

Yes, this is the final result.

No, that's not a "result", just an oversized photograph of a monitor showing some LabVIEW code. Attach the VI instead.

I apologise for the misunderstanding.
