private boolean isEitherSeriesDegenerate ( XYDataset x_dataset , boolean x_impliedZeroSubtrahend ) { if ( x_impliedZeroSubtrahend ) { return ( x_dataset . getItemCount ( 0 ) < 2 ) ; } return ( ( x_dataset . getItemCount ( 0 ) < 2 ) || ( x_dataset . getItemCount ( 1 ) < 2 ) ) ; }
determines if a dataset is degenerate . a degenerate dataset is a dataset where either series has less than two ( 2 ) points .
