Class Overview

A renderer that draws a line connecting the start and end Y values for an XYPlot. The example shown here is generated by the YIntervalRendererDemo1.java program included in the JFreeChart demo collection:

Inherited Fields
From class org.jfree.chart.renderer.AbstractRenderer
Public Constructors
YIntervalRenderer()
The default constructor.
Public Methods
Object clone()
Returns a clone of the renderer.
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.
boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object.
Range findRangeBounds(XYDataset dataset)
Returns the range of values the renderer requires to display all the items from the specified dataset.
XYItemLabelGenerator getAdditionalItemLabelGenerator()
Returns the generator for the item labels that appear near the lower y-value.
void setAdditionalItemLabelGenerator(XYItemLabelGenerator generator)

Public Constructors

public YIntervalRenderer ()

The default constructor.

Public Methods

public Object clone ()

Returns a clone of the renderer.

Returns
  • A clone.
Throws
CloneNotSupportedException if the renderer cannot be cloned.

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).

public boolean equals (Object obj)

Tests this renderer for equality with an arbitrary object.

Parameters
obj the object (null permitted).
Returns
  • A boolean.

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).

public XYItemLabelGenerator getAdditionalItemLabelGenerator ()

Returns the generator for the item labels that appear near the lower y-value.

Returns
  • The generator (possibly null).

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).
