Equalizer Screen Spectrum doesn't match

I fed pink noise to the player to get a uniform distribution. Then I produced some peaks in the distribution by attenuating most frequencies and enabling just one. I would have expected to see a match between the equalizer curve and the spectrum. As shown in the appended screenshots it didn't work that way.

This seems to be a design flaw. The equalizer is equally distributed per octave, that means its x-axis is logarithmic. The spectrums, generally for the visualization and especially the one used for the equalizer screen, have a linear x-axis( can be seen when playing white noise - the spectrums then show a uniform distribution, as they should ).

So these two don't fit together. 

An equalizer screen spectrum which uses equal amount of space on the x-axis per octave would be better.

Visualization doesn't match equalizer bands. You have much more "bass" bars vs equalizer bands. This is mostly due to visualization focused on good music matching / visualization (so it needs better resolution in low freqs.) and equalizer being almost strictly octave based.

Yes, thank you ! I tried an exponential and a linear sinus sweep - the visualization is neither linear nor logarithmic, it seems to concentrate on the middle ground, so to speak where most of the music plays ?
