Based on my experience using inSSIDer; i have never
seen a signal stronger than -40dB or weaker than about -80dB;
so a amplitude range of -15dB to -100dB results in a 'compressed'
graph where the action is and a lot of wasted black space on the screen.
so my request is simply - please allow the user to set/modify the maximum
and minimum amplitude values so we can use our screens more efficiently and
get bigger clearer graphs.
