• Gain adjust (scale):
o Normalise to 0dB - the selected plots will be shifted in the vertical axis so that they are centered
around 0 dB, whilst maintaining their relative levels.
The scale for an individual plot can also be adjusted by entering a value in the Scale column for
the relevant plot.
o Reset - this reverses the shift applied by the Normalise to 0dB button. Again, it is applied only to
the selected plots. This means, for example, if two plots have been normalised to 0dB, then one
plot is de-selected, then Reset applied, then the de-selected plot selected again, one plot will be
still normalised and the other plot will be reset.
o Sum - this sums the selected plots by creating a new plot called Sum. This plot is shown and
the selected or 'source' plots are automatically hidden (ie de-selected).
The sum plot is created without smoothing - it has been generated from the original, unsmoothed
'source' plots.
