Thanks, I'm happy it's proving useful.

try 

#+PLOT: set:"xlabel 'Frequency'"

You need the double " quotes for any argument that contains spaces, and
gnuplot requires quotes (in this case using single ' quotes) around the
argument to xlabel.

I agree this isn't obvious, if you have a suggestion for improving the
syntax please let me know.

I agree, if I find time I will look at implementing it.
