net.sourceforge.jiu.color.data.Histogram3D
An interface for classes that store three-dimensional histograms. Histograms count the occurrence of values, so a three-dimensional histogram has counters for three-dimensional values. The 3D histograms are used (as an example) to count the occurrence of each color in an RGB image. @author Marco Schmidt @see Histogram1D

        double yRange = height * dy;
        double yMin = y0 - yRange / 2.0;
        double yMax = y0 + yRange / 2.0;


        distribution =
                new Histogram3D(xMin, xMax, width, yMin, yMax, height, min,
                        max, bins);
