Method from org.jfree.data.xy.AbstractXYZDataset Detail:
public double getZValue(int series, int item) { double result = Double.NaN; Number z = getZ(series, item); if (z != null) { result = z.doubleValue(); } return result; } Returns the z-value (as a double primitive) for an item within a series.

Method from org.jfree.data.xy.AbstractXYZDataset Detail:
