REW measured THD question / possible feature request

[Olen Rasp]

Hi,
Is it possible to plot THD in percentage on a linear y-scale? So far I can only plot percentage in a log scale. Also is it possible to plot two different THD plots simultaneously? I often find it useful to plot two THD plots on a linear scale when comparing different speaker implementations to look for less obvious differences.
Thanks!
Olen

No, the underlying data remains log, only the axis labels are changed.

Yes, use the Overlays distortion graph.

This is great! Thank you John!

One issue I noticed is that when I toggle the 'Use harmonic frequency as ref' check box on the Overlays Distortion plot it didn't switch back and forth, I realized changing one distortion plot (standard or overlays) changes both (which makes sense). If I go to the standard distortion plot window I needed to uncheck the 'plot harmonics as the harmonic frequency box' for the toggle in the Overlays window to work.

Again not a major issue, just wanted to post this in case somebody else encounters the same issue.

I'm using v5.31.1 Pro

Thanks again!
