great - thanks for your answer. I got it run now on OS X via simple
macports install. However I will follow the issue from time to time, as
I think it would be great to have beignet available for this (and other)
Also I am keen on looking into how the colored spectrum view is
implemented by you ( I have no glue and have not yet looked into it).
HOWEVER: I did some offline studies on this kind of plots a while ago in
python. what I found to look nice was the following idea:
Plot like a monochrome FFT with persistence on and where each of the
line has some alpha (even the first one). So naturally the more often a
peak occurs with the same level, the stronger (or more opaque) the point
will be. Then apply a simple jet colormap (or any other suitable
colormap) to the monochrome plot. As said, I have not looked into your
code yet, chances are you are doing exactly that.
This, by the way would not only make sense for the spectrum view, but
also for the scope as it gives some nice colored eye-diagrams.
Also I read earlier, that someone was asking about the benefit of this
kind of plot with respect to a simple FFT (with persistence). The
benefit of course is that you can see the probability distribution at
frequency points of interest (f = const-line) and that you still see
single occurring events, as they will not be very weak as in a FFT with
persistence, but have some dedicated good visible color for a while.
