Class HighLowRenderer

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.
Constructor Summary
HighLowRenderer()
The default constructor.
Method Summary
Objectclone()
Returns a clone of the renderer.
voiddrawItem(Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)
Draws the visual representation of a single data item.
booleanequals(Object obj)
Tests this renderer for equality with an arbitrary object.
PaintgetCloseTickPaint()
Returns the paint used to draw the ticks for the close values.
booleangetDrawCloseTicks()
Returns the flag that controls whether close ticks are drawn.
booleangetDrawOpenTicks()
Returns the flag that controls whether open ticks are drawn.
PaintgetOpenTickPaint()
Returns the paint used to draw the ticks for the open values.
voidsetCloseTickPaint(Paint paint)
Sets the paint used to draw the ticks for the close values and sends a RendererChangeEvent to all registered listeners.
voidsetDrawCloseTicks(boolean draw)
Sets the flag that controls whether close ticks are drawn, and sends a RendererChangeEvent to all registered listeners.
voidsetDrawOpenTicks(boolean draw)
Sets the flag that controls whether open ticks are drawn, and sends a RendererChangeEvent to all registered listeners.
voidsetOpenTickPaint(Paint paint)
Sets the paint used to draw the ticks for the open values and sends a RendererChangeEvent to all registered listeners.

Constructor Detail

HighLowRenderer

public HighLowRenderer()
The default constructor.

Method Detail

clone

public Object clone()
Returns a clone of the renderer.

Returns: A clone.

Throws: CloneNotSupportedException if the renderer cannot be cloned.

drawItem

public void drawItem(Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)
Draws the visual representation of a single data item.

Parameters: g2 the graphics device. state the renderer state. dataArea the area within which the plot is being drawn. info collects information about the drawing. plot the plot (can be used to obtain standard color information etc). domainAxis the domain axis. rangeAxis the range axis. dataset the dataset. series the series index (zero-based). item the item index (zero-based). crosshairState crosshair information for the plot (null permitted). pass the pass index.

equals

public boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object.

Parameters: obj the object (null permitted).

Returns: A boolean.

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).

getDrawCloseTicks

public boolean getDrawCloseTicks()
Returns the flag that controls whether close ticks are drawn.

Returns: A boolean.

getDrawOpenTicks

public boolean getDrawOpenTicks()
Returns the flag that controls whether open ticks are drawn.

Returns: A boolean.

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).

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).

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.

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.

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).
