Constructor Detail

DensityPlotEvent

public DensityPlotEvent(Component source,
                        DensityPlotState plotState,
                        int nPotential,
                        int nIncluded,
                        int nVisible,
                        double[] loCuts,
                        double[] hiCuts)

Constructor.

Parameters:

source - source of this event

plotState - plot state reflected by this change event

nPotential - total number of points available

nIncluded - number of points included in marked subsets

nVisible - number of points actually plotted

loCuts - nchannel-element array of lower bin cut levels

hiCuts - nchannel-element array of upper bin cut levels

Method Detail

getLoCuts

public double[] getLoCuts()

Returns lower cut values for the channels plotted. These are the bin counts below which pixels will be coloured at the low-end colour. For an unweighted plot these values will be integers.

Returns:

array giving absolute lower cut levels for each channel

getHiCuts

public double[] getHiCuts()

Returns upper cut values for the channels plotted. These are the bin counts above which pixels will be coloured as the high-end colour. For an unweighted plot these values will be integers.

Returns:

array giving absolute upper cut levels for each channel
