    • hasLabels

      public boolean hasLabels()
      Description copied from interface: PlotData
      Indicates whether there are or may be text labels associated with the data points in this object.
      Specified by:
      hasLabels in interface PlotData
      Returns:
      true if PointSequence.getLabel() may have non-null returns

    • getPointSequence

      public PointSequence getPointSequence()
