Method from org.jfree.data.xy.AbstractXYDataset Detail:
public DomainOrder getDomainOrder() { return DomainOrder.NONE; } Returns the order of the domain (X) values.
public double getXValue(int series, int item) { double result = Double.NaN; Number x = getX(series, item); if (x != null) { result = x.doubleValue(); } return result; } Returns the x-value (as a double primitive) for an item within a series.
public double getYValue(int series, int item) { double result = Double.NaN; Number y = getY(series, item); if (y != null) { result = y.doubleValue(); } return result; } Returns the y-value (as a double primitive) for an item within a series.
