public interface XYItemRenderer
Interface for rendering the visual representation of a single (x, y) item on an XYPlot.

To support cloning charts, it is recommended that renderers implement both the Cloneable and PublicCloneable interfaces.

  • Method Details

    • initialise

      XYItemRendererState initialise​(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset dataset, PlotRenderingInfo info)
      Initialises the renderer then returns the number of 'passes' through the data that the renderer will require (usually just one). This method will be called before the first item is rendered, giving the renderer an opportunity to initialise any state information it wants to maintain. The renderer can do nothing if it chooses.
      Parameters:
      g2 - the graphics device.
      dataArea - the area inside the axes.
      plot - the plot.
      dataset - the dataset.
      info - an optional info collection object to return data back to the caller.
      Returns:
      The number of passes the renderer requires.

    • getPassCount

    • getPlot

      XYPlot getPlot()
      Returns the plot that this renderer has been assigned to.
      Returns:
      the plot.

    • setPlot

      void setPlot​(XYPlot plot)
      Sets the plot that this renderer is assigned to.

      This method will be called by the plot class...you do not need to call it yourself.

      Parameters:
      plot - the plot.

    • getRangeType

      RangeType getRangeType()
      Returns the range type for the renderer. The plot needs to know this information in order to determine an appropriate axis range (when the axis auto-range calculation is on).

      Two types are recognised:

      • STANDARD - data items are plotted individually, so the axis range should extend from the smallest value to the largest value;
      • STACKED - data items are stacked on top of one another, so to determine the axis range, all the items in a series need to be summed together.
      If the data values are stacked, this affects the axis range required to display all the data items.
      Returns:
      a flag indicating whether or not the data values are stacked.

    • getRangeExtent

      Range getRangeExtent​(XYDataset dataset)
      Returns the range of values the renderer requires to display all the items from the specified dataset.
      Parameters:
      dataset - the dataset (null permitted).
      Returns:
      The range (or null if the dataset is null or empty).

    • addChangeListener

      void addChangeListener​(RendererChangeListener listener)
      Add a renderer change listener.
      Parameters:
      listener - the listener.

    • removeChangeListener

      void removeChangeListener​(RendererChangeListener listener)
      Removes a change listener.
      Parameters:
