Class HighLowRenderer

All Implemented Interfaces:
Serializable, Cloneable, EventListener, AnnotationChangeListener, LegendItemSource, XYItemRenderer, PublicCloneable

public class HighLowRenderer extends AbstractXYItemRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable
A renderer that draws high/low/open/close markers on an XYPlot (requires a OHLCDataset). This renderer does not include code to calculate the crosshair point for the plot. The example shown here is generated by the HighLowChartDemo1.java program included in the JFreeChart Demo Collection:

    • getDrawOpenTicks

      public boolean getDrawOpenTicks()
      Returns the flag that controls whether open ticks are drawn.
      Returns:
      A boolean.
      See Also:
    • setDrawOpenTicks

      public void setDrawOpenTicks(boolean draw)
      Sets the flag that controls whether open ticks are drawn, and sends a RendererChangeEvent to all registered listeners.
      Parameters:
      draw - the flag.
      See Also:
    • getDrawCloseTicks

      public boolean getDrawCloseTicks()
      Returns the flag that controls whether close ticks are drawn.
      Returns:
      A boolean.
      See Also:
    • setDrawCloseTicks

      public void setDrawCloseTicks(boolean draw)
      Sets the flag that controls whether close ticks are drawn, and sends a RendererChangeEvent to all registered listeners.
      Parameters:
      draw - the flag.
      See Also:
    • getOpenTickPaint

      public Paint getOpenTickPaint()
      Returns the paint used to draw the ticks for the open values.
      Returns:
      The paint used to draw the ticks for the open values (possibly null).
      See Also:
    • setOpenTickPaint

      public void setOpenTickPaint(Paint paint)
      Sets the paint used to draw the ticks for the open values and sends a RendererChangeEvent to all registered listeners. If you set this to null (the default), the series paint is used instead.
      Parameters:
      paint - the paint (null permitted).
      See Also:
    • getCloseTickPaint

      public Paint getCloseTickPaint()
      Returns the paint used to draw the ticks for the close values.
      Returns:
      The paint used to draw the ticks for the close values (possibly null).
      See Also:
    • setCloseTickPaint

      public void setCloseTickPaint(Paint paint)
      Sets the paint used to draw the ticks for the close values and sends a RendererChangeEvent to all registered listeners. If you set this to null (the default), the series paint is used instead.
      Parameters:
      paint - the paint (null permitted).

    • getTickLength

      public double getTickLength()
      Returns the tick length (in Java2D units).
      Returns:
      The tick length.
      See Also:
    • setTickLength

      public void setTickLength(double length)
      Sets the tick length (in Java2D units) and sends a RendererChangeEvent to all registered listeners.

    • findRangeBounds

      public Range findRangeBounds(XYDataset dataset)
      Returns the range of values the renderer requires to display all the items from the specified dataset.

      findRangeBounds in interface XYItemRenderer
      Overrides:
      findRangeBounds in class AbstractXYItemRenderer
      Parameters:
      dataset - the dataset (null permitted).
      Returns:
