Something for "next" in the GUI area

The ability to set your own axis-labelling function for the FFT display
would be useful for certain types of applications where the frequency is
actually
interpreted as something else–like doppler shift, for example.

I’m thinking that you could pass a function that takes the generated
list of frequencys, and the current center frequency:

axis_label_function (float listoffreqs[], float center_freq)

returns float listoflabels[]

or perhaps

returns string listoflabels[]

This is obviously driven by my radio astronomy stuff, but I imagine that
radar applications and others might want “weird” axis labels on the
FFT display.

Similarly it should be easy to change the Axis title to something other
than the default.

I see. Good suggestion, most likely doable.

Feeling like a broken record today, but I’m on the road and many
things are going on. Instead of losing this idea to the mailing list,
please add a new feature request on the issue tracker of the wiki.
