[Discuss-gnuradio] Something for "next" in the GUI area

[Marcus D. Leech]

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.
