                            int item)

  Returns the y-value (as a double primitive) for an item within a series.

  Specified by:
    `getYValue` in interface `XYDataset`
  Parameters:
    `series` - the series index (zero-based).
    `item` - the item index (zero-based).
  Returns:
    The value.
