I would like some help to be able to now make a plot at a fixed Freq but different Temps (so plot will have 3 graphs:25, -30, +70 for the same freq say 136). Thanks for your help and time, hiNi.

This crude code will work for any number of temperatures and even allow for varying sizes of each array (say you measured 3 points at 1 temp and 6 points at another). I highly doubt this is necessary but it's how the code works. Just drop this in and connect the correct arrays loaded from you text file in place of the array controls i've used. (or you can wire the terminals and use it as a sub-vi).
