public class XYItemRendererState extends RendererState
The state for an XYItemRenderer.
  • Field Details

    • workingLine

      public Line2D workingLine
      A line object that the renderer can reuse to save instantiating a lot of objects.
  • Constructor Details

    • XYItemRendererState

      public XYItemRendererState(PlotRenderingInfo info)
      Creates a new state.
      Parameters:
      info - the plot rendering info.
  • Method Details

    • getProcessVisibleItemsOnly

      public boolean getProcessVisibleItemsOnly()
      Returns the flag that controls whether the plot passes all data items in each series to the renderer, or just the visible items. The default value is true.
      Returns:
      A boolean.

    • setProcessVisibleItemsOnly

      public void setProcessVisibleItemsOnly(boolean flag)
      Sets the flag that controls whether the plot passes all data items in each series to the renderer, or just the visible items.
      Parameters:
      flag - the new flag value.
    • getFirstItemIndex

      public int getFirstItemIndex()
      Returns the first item index (this is updated with each call to startSeriesPass(XYDataset, int, int, int, int, int).
      Returns:
      The first item index.
    • getLastItemIndex

      public int getLastItemIndex()
      Returns the last item index (this is updated with each call to startSeriesPass(XYDataset, int, int, int, int, int).
      Returns:
      The last item index.
    • 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.

    • endSeriesPass

      public void endSeriesPass(XYDataset dataset, int series, int firstItem, int lastItem, int pass, 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.
