Background corrections in line plots

[TimWolz]

If I have a 2d plot, say VNA frequency over current, and want to normalize my data by the average values over the x-axis (current) for each freqpoint, it works fine in the color plot. However, it would also be nice to have background corrected traces in the line plots. Here, the average is calculated along one trace and not for each freqpoint over all traces. So the line plot / trace is only scaled and not corrected by the background.

Do I understand correctly:
Instead of the 1d traces individually averaged or subtracted, you propose that the same manipulation applied to the 2d dataset (for instance divide all (current)traces by the first (current)trace) is applied to the individual traces also when switching from colorplot to line plot? So instead of locally applied manipulations you want to see a line plot of trace x still divided by trace 0 which is not currently shown?
