      Specified by:
      getItemCount in interface XYDataset
      Parameters:
      series - the series index (in the range 0 to getSeriesCount() - 1).

      Description copied from interface: XYDataset
      Returns the x-value for an item within a series. The x-values may or may not be returned in ascending order, that is up to the class implementing the interface.

      getX in interface XYDataset
      Parameters:
      series - the series index (in the range 0 to getSeriesCount() - 1).
