[Discuss-gnuradio] How to set the bandwidth in WX GUI FFT Sink

Hello,

I have a USRP B100 from Ettus and I am receiving FM Radio. I plotted the RF Spectrum and the baseband spectrum in a notebook, but I don't know how to change the frequency axis or zoom in the graph. I want to know if it possible to change the frequency in the same graph as well.

I tried to do it but I can't. I am a newbie so I really appreciate your help.

Thanks in advance,

Pablo Fernandez
