Comment (by RKleinert):

 Replying to [comment:5 Elon Musk]:
 > The frequency log scale axis matches the spectrum output.
 > What you want would make high spectrum content not displayed at all.

 > Imagining you want: 0.1 1 10 100 1000 scale.

 Yes, that is what I would understand as a log-scaled y-axis.
