Gnuradio: FFT plot for 1 sample

I'm using GNU Radio for receive radio signal and write it to file (complex) with metadata. Then I parse file in python and I have variable with 1 sample (8 byte). I want to build FFT plot for just 1 specific sample or save it as image. Is that real? Can I do that with GRC, or maybe python have lib for that? Thank you

Your question makes no sense: the FFT of a single sample is just that sample. That's the definition of an FFT.

Think of it that way: a spectrum tells you which frequencies are in a signal.

What frequency components are in the signal "0.23" ? Only exactly one frequency component: a constant component of amplitude 0.23.
