I was trying to understand if there's a(n easy) way to plot a spectrum. I guess it should be easily feasible, as I saw both pd capabilties in time domain, both Miller Puckette's figures in the book. But looking in docs and on the web I got confused and I'm not able to find answers to my question.

You can combine [fft~] with [tabsend~] and [table]. Clicking on the [table] will show you the contents. If you want to make a polar transform, you may want to combine cos and sin like [expr~ sqrt($v1*$v1+$v2*$v2)] to get an amplitude plot. If you want a phase plot you can use [expr~ atan($v1,$v2)] or maybe it's $v2 first.

If you want something fancier, have a look at http://gridflow.ca/gallery/spectrogram.gif
