linear vs polynomial order 1 curve fit VI

[GerdW]

Hi,

when using random data (similar to your images) I get meaningful linear fits:

Thanks Altenbach.  The issue was with relative vs. absolute time of the signal.  Changing to relative time fixes this for the linear curve fit.  It is unclear why the polynomial order 1 fit is able to work without needing to appropriately condition the signal.  It seems like an odd error to have, expecially given the fact that these are all "easy" modules for newbies like myself to use.

I have attached an even simpler VI showing this fix working appropriately.

Doing a logical OR of a boolean with itself does not seem very reasonable. Do you typically connect e.g. a stop button to one of the inputs?

[mparagano]

I typically don't use that input; it should be removed as it serves no purpose

[mparagano]

I mean that the logical OR with the Boolean should be removed... I could separately enable the DAQ assistant with that input by right now I'm one having it be always on with the VI
