The transmission quality is visualised in a qualitative way using a colour range for
the symbol density concentrated in a certain area. This colour coding goes from
black (no symbols) to red (maximum density), and runs from blue to yelllow in
ascending order.
A greater dispersion of the symbols indicates greater level of noise or worse signal
quality.
If concentration of symbols or noise appears is indicative of good carrier/noise ratio
or absence of problems as phase noise, etc.,.
