snr in fm modulation

Does there anyone know how to get the SNR from a modulation FM signal spectrum plot?

Thank you for your help.........

Added after 2 minutes:

BTW the FM modulation plot was in Matlab format

 

[wwfhm2002]

If you know the modulation signal is X Khz sine wave, and deviation is also known Y KHz, then you know the signal frequency (such X, X+Y, X+2Y) at FM signal according to FM modulation principle (many book have it), other frequencies are noise.
