I needed to create upper and lower limits test based on our engineering spec. So I used the "Limit testing" VIs that came with my NI Developer system. Everything worked great when I created simulated data. The problem arose when I tried to use my real-time data with the upper and lower limits vi. I thought the problem was due to the engineering limits being on one scale and the realtime data on another. But resorting to "Limit Specs. for unevenly sampled data" didn't help. More than likely, it may be that I don't understand how to set this all up correctly.

Is the problem that one array is longer than the other two? I thought it would be an easy matter of one-to-one mapping of a Y value to a psi value on an X scale.
