[Discuss-gnuradio] Question about Plotting the Spectrum(Power against frequency) with usrp_sense.py

[Leo Yang]

Question about the spectrum plot of the usr_sense.py:
I have modified the old usrp_spectrum_sense.py to fit the latest version of
gnuradio, and now I can run the program and export the m.data into a txt
file, I wonder how to plot the dynamic graph of power against frequency for
the visualization of the spectrum analyzer.
Any direction or examples will be very helpful for me. 

Thanks a lot 


here is the source code of usrp_spectrum_sense.py
