The for loop runs through all the samples and populates the trends on the second tab, and the bottom loop allows the user to step through each sample and look at the spectrum for each channel.
The for loop runs through all the samples and populates the trends on the second tab (it is grabbing peaks and trending them for the whole file), and the bottom loop allows the user to step through each sample and look at the spectrum for each sample.
So, if you actually looked at the spectrum in the for loop you would need to increment to the last sample in the other spectrum to compare the two. This was just the first way that came into my head to be able to trend certain peaks right when the program launches, but also be able to step through the spectrums for each sample.
