Is there an easy way to set the bandwidth for the fft_sink display?
I’ve filtered the original signal to the frequencies of interest but in
FFT sink the X axis is over 2MHz wide with my signals clustered into the
centre. I’d like the X axis range to reflect the range of frequencies
present in my input signal (a few tens of KHz) rather than leaving most
the display blank and clustering all the buckets I care about into the
central 10% of the panel width.
