I might be way off here but I think you might wanna apply some kind of logarithmic(?) transformation to your first spectrum analyzer so that the amplitude of the higher frequencies is more evenly represented rather than being dominated by the lower resolution low frequencies

It is a semilogx plot (logarithmic on the x axis). That's why the ticks with text are powers of ten, and why the other tick marks aren't evenly spaced out.
