Plots positive energy values of a cepstrum to stdout. The energy value is assumed to be the first element of the double array returned by Data.getValues(). For negative energy value, a "-" will be printed out. The plots look like the following, one line per cepstrum. The energy value for that particular cepstrum is printed at the end of the line.
The maximum level of energy for which a plot string will be preconstructed.
Plots the energy values of the given Data to System.out.
Plots the energy values of the given Data to System.out. If the Data contains a signal, it prints the signal.
