Need help with a time time lag.

[Virgil]

I am a relative novice to labview and have a problem.
I have two waveforms being aquired; one from a flow sensor the other
form a gas analyser. There is a small delay between the flow signal
relative to the analyser (due to the transit time of the gas to the
analyser). What I want to do is compensate for this lime lag and then
plot the corrected waveform to plot an XY graph. This is essentialy a
phase delay that needs to be compensated for.

Can anyone help me solve my problem.

Cheers
Virgil.

Here is a possible solution. The idea is to use the Get Waveform Subset funciton on the longer of the two functions. This way you return the exact subset that matches.
