Two suggestions from my side:
If you want to use Python, you can use the Spyder IDE
(https://code.google.com/p/spyderlib/). Spyder is mainly designed for
scientific programming. It even has built-in plotting capabilities.
Another package I have used for that purpose is kst-plot. It is fast and
I tried rebuilding gr-air-modes with make -j1 both for build and

setting to 1 and rebuilt gnuradio, rtl_sdr..., but the problem is still
there.

Kevin, are you building gnuradio via PyBombs ? In this case you must
have doxygen installed on your system. Then you have to edit the build
recipe for gnuradio to enable doxygen:
open the file gnuradio.lwr in your pybombs/recipes folder.
in the line starting with var config_opt change
May I then suggest to enable the docs in the pybombs recipe by default
as well ?

I just updated to the latest pybombs and recipes and I notice that a lot
