      • startSeriesPass

        public void startSeriesPass​(XYDataset dataset,
                                    int series,
                                    int firstItem,
                                    int lastItem,
                                    int pass,
                                    int passCount)
        This method is called by the XYPlot when it starts a pass through the (visible) items in a series. The default implementation records the first and last item indices - override this method to implement additional specialised behaviour.
        Parameters:
        dataset - the dataset.
        series - the series index.
        firstItem - the index of the first item in the series.
        lastItem - the index of the last item in the series.
        pass - the pass index.
        passCount - the number of passes.

                                  int firstItem,

                                  int passCount)
        This method is called by the XYPlot when it ends a pass through the (visible) items in a series. The default implementation does nothing, but you can override this method to implement specialised behaviour.
        Parameters:
        dataset - the dataset.
        series - the series index.
        firstItem - the index of the first item in the series.
        lastItem - the index of the last item in the series.
        pass - the pass index.
        passCount - the number of passes.
