Hello,

I think either some notifer was missing which didn't update the orthogonal
axis correctly when you swapped the dim mapping (quite possible) or you
need to edit the minimum and maximum aliased frequencies of your spectrum.
Until you asked this question I had even forgotten what algorithm we use
to determine the range of the orthogonal scrollbars, but it looks like it
takes the union of the ranges for each spectrum that is mapped into that
window (but no larger than the universe specified for that axis type under
the Other --> Axes and Panels dialog).

In either case you should be able to fix this by going into the Edit
Spectrum Referencing dialog (so Experiment --> Edit Spectra and then click
on the Referencing button at the bottom).  The minimum and maximum aliased
frequencies are set in the rightmost two columns and if you just change
those, to be at least as big as what you want (and then back again if the
original was really what you wanted)  then hopefully that will fix the
problem.  (I just checked and changing that does call a notifier, so the
scrollbar region is updated.)
