Class ClickFFTPlotManager2

java.lang.Object

dataPlotsFX.data.FFTPlotManager

dataPlotsFX.clickPlotFX.ClickFFTPlotManager2

public class ClickFFTPlotManager2
extends FFTPlotManager

Handles efficiently plotting click FFT's on the frequency axis. This can be used to visualise longer clicks, for example, bat calls.

Warning: this display does not work if there are not unique UID values for clicks.

drawDataUnit

public void drawDataUnit(javafx.scene.canvas.GraphicsContext g,
 PamDataUnit pamDataUnit,
 ScrollingImageSegmenter.WritableImageSegment writableImage,
 TDProjectorFX tdProjector,
 double scrolLStart,
 int chanClick)

Description copied from class: FFTPlotManager

Draw the data unit on a writeable image segment. This function can be overriden for more options on drawing.

Overrides:

drawDataUnit in class FFTPlotManager

Parameters:

g - - the graphics context

pamDataUnit - - the data unit to draw.

writableImage - - the writiable image.

tdProjector - - the projector.

scrolLStart - - the start of the scroller.

chanClick - - the channel of the data unit to plot. This is the relative, not the absolute channel

drawClickFFT

public void drawClickFFT(double[] spectrum,
 double timeMillis,
 double maxFreq,
 ScrollingImageSegmenter.WritableImageSegment writableImage)

Draw a single click FFT

Parameters:

spectrum - - the click spectrum in FFT bins.

maxFreq - - the max frequency in Hz;

g - - the graphics handle

tC - -the time in pixels

tdProjector - - the projector

getSpectrogram

public double[][] getSpectrogram(PamDataUnit pamDataUnit,
 int chanClk)

Description copied from class: FFTPlotManager

Get the spectrogram from a data unit based on the FFT settings

Specified by:

getSpectrogram in class FFTPlotManager

Parameters:

pamDataUnit - - the data unit.

chanClk - - the spectrogram channel - this is the realtive channel within the data unit. Not the absolute channel.

Returns:

the absolute spectrogram data.
