Class YIntervalRenderer

public class YIntervalRenderer extends AbstractXYItemRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable

A renderer that draws a line connecting the start and end Y values for an XYPlot.
Constructor Summary
YIntervalRenderer()
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.
RangefindRangeBounds(XYDataset dataset)
Returns the range of values the renderer requires to display all the items from the specified dataset.
XYItemLabelGeneratorgetAdditionalItemLabelGenerator()
Returns the generator for the item labels that appear near the lower y-value.
voidsetAdditionalItemLabelGenerator(XYItemLabelGenerator generator)
Sets the generator for the item labels that appear near the lower y-value and sends a RendererChangeEvent to all registered listeners.

Constructor Detail

YIntervalRenderer

public YIntervalRenderer()
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 (ignored here).

equals

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

Parameters: obj the object (null permitted).

Returns: A boolean.

findRangeBounds

public Range findRangeBounds(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 (null if the dataset is null or empty).

getAdditionalItemLabelGenerator

public XYItemLabelGenerator getAdditionalItemLabelGenerator()
Returns the generator for the item labels that appear near the lower y-value.

Returns: The generator (possibly null).

Since: 1.0.10

setAdditionalItemLabelGenerator

public void setAdditionalItemLabelGenerator(XYItemLabelGenerator generator)
Sets the generator for the item labels that appear near the lower y-value and sends a RendererChangeEvent to all registered listeners. If this is set to null, no item labels will be drawn.

Parameters: generator the generator (null permitted).

Since: 1.0.10
