Note that while the reference values at the top of both y-axes are now identical, the
reference values indicated in the window title bars are not. This is due to the fact
that, by default, in AF time domain displays the reference value is defined at the
reference position 50 % (=center of diagram), while in AF frequency domains it is
defined at the position 100 % (= top of diagram).
