How do you calculate the slope of a line

[Fiddler918]

I am trying to calculate the slope of a line between two distinct points (4 deg/sec and 298 deg/sec).  I am using a Threshold 1D array to intiate the calculation at 4 deg/sec but I don't know how to stop the calcuation at 298 deg/sec.  I have attached the VI and an example of the text file I running through it.  Any help would be greatly appreciated.  Thanks.

Just use anothe threshold array wired into a split array split array

Do another threshold at 298 and use it to calculate the lenght input for "array" subset.

(Of course you would probably need a little bit mode code to deal with pathological data....)

a BUG?  Christian I'm shocked!

(change the value of the dbl from 296 to 298 and round up)

Got it!  Thank you, I have literally spent hours trying to figure this out.  I'm obviously quite a LabVIEW rookie:)

Not a bug, just a typo. 😄

We get fractional indices anyway and there are plenty of points, so I did not worry about rounding or precision (I doubt one point would dramatically change the slope). Nothing a +1 or -1 here or there cannot fix if needed. 😄
