REW Beta Release I don't understand a thing

[maverikc]

Hi. I don't understand a thing. When I view the distortion versus input voltage graph
and select dB for the Y axis, the graph is clear to me.


But when I change for the y axis from dB to % the
input signal (in the graph) is represented as a constant with a very high dB value.


Thanks for those who want to help me

When distortion is plotted in percent everything is a percentage of the input level, so the input level itself is 100 %. REW shows you the dB level of the input in the legend as the level may have varied versus frequency, but that can't be shown on a percentage graph.
