setting zero reference line to multiple points

[jonhelpmejon]

I have multiple x,y points.  I would like to chose 2 y points and set them to zero as a reference line, then calculate the deviation of all other points from this reference line.  Does labview have a function that can do this.  Thanks.

Like a regression analysis?  Look at all the VI's under probability and statistics on the mathematics palette.

Thanks, I took a look.  I just want to select 2 points in my data, set them to zero, and reference all other points to this straight line.

Just do a linear fit to the two points and subtract the result from all of the data points.  See example (quick and dirty and potentially buggy).
