      Returns:
      The key for a series.
      Throws:
      IllegalArgumentException - if series is not in the specified range.

    • indexOf

      public int indexOf(VectorSeries series)
      Returns the index of the specified series, or -1 if that series is not present in the dataset.

      series - the series (null not permitted).
      Returns:
      The series index.

    • getItemCount

      public int getItemCount(int series)
      Returns the number of items in the specified series.
      Specified by:
      getItemCount in interface XYDataset
      Parameters:
      series - the series (zero-based index).
      Returns:
      The item count.
      Throws:
