We have two ears and one mouth so that we can listen twice as much as we speak.

Are you rewriting the data to a Waveform Graph? I'm wondering if this might be a dataflow issue. If you haven't yet, please check out these tutorials on LabVIEW.
Does the graph change at all after you perform the subtraction? Are you subtracting the difference from an array of values? If you need to post some code to make your application clear, please post a very small example that demonstrates the problem.
