Class EnergyPlotter

java.lang.Object

edu.cmu.sphinx.frontend.util.EnergyPlotter

All Implemented Interfaces:

Configurable

public class EnergyPlotter
extends java.lang.Object
implements Configurable

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.

newProperties

public void newProperties(PropertySheet ps)
                   throws PropertyException

Description copied from interface: Configurable

This method is called when this configurable component needs to be reconfigured.

Specified by:

newProperties in interface Configurable

Parameters:

ps - a property sheet holding the new data

Throws:

PropertyException - if there is a problem with the properties.

plot

public void plot(Data cepstrum)

Plots the energy values of the given Data to System.out. If the Data contains a signal, it prints the signal.

Parameters:

cepstrum - the Data to plot
