Constructor & Destructor Documentation

org.math.plot.plots.GaussianDensityLayerPlot.GaussianDensityLayerPlot	(	Plot	p,
		int	ax,
		double[]	sigma
	)

Build a gauss quantile plot based on given plot. The quantile is drawn as a gaussian gradient from the base plot dots.

Parameters:

	p	base plot
	a	axis number of quantile : 0=X quantile, 1=Y quantile, 2=Z quantile
	sigma	array of standard deviation values
