- All Implemented Interfaces:
- java.lang.Cloneable, LegendItemSource, java.io.Serializable, XYItemRenderer
- public class ClusteredXYBarRenderer
- extends XYBarRenderer
- implements java.lang.Cloneable, java.io.Serializable
An extension of XYBarRenderer
that displays bars for different
series values at the same x next to each other. The assumption here is
that for each x (time or else) there is a y value for each series. If
this is not the case, there will be spaces between bars for a given x.
This renderer does not include code to calculate the crosshair point for the plot.

ClusteredXYBarRenderer
public ClusteredXYBarRenderer()
- Default constructor. Bar margin is set to 0.0.
ClusteredXYBarRenderer
public ClusteredXYBarRenderer(double margin,
boolean centerBarAtStartValue)
- Constructs a new XY clustered bar renderer.
- Parameters:
margin
- the percentage amount to trim from the width of each bar.centerBarAtStartValue
- If true, bars will be centered on the start of the time period.
initialise
public XYItemRendererState initialise(java.awt.Graphics2D g2,
java.awt.geom.Rectangle2D dataArea,
XYPlot plot,
XYDataset data,
PlotRenderingInfo info)
- Initialises the renderer. Here we calculate the Java2D y-coordinate for zero, since all
the bars have their bases fixed at zero. Copied from superclass to
initialize local variables.
- Specified by:
initialise
in interface XYItemRenderer
- Overrides:
initialise
in class XYBarRenderer
- Parameters:
g2
- the graphics device.dataArea
- the area inside the axes.plot
- the plot.data
- the data.info
- an optional info collection object to return data back to the caller.
- Returns:
- The number of passes required by the renderer.
setMargin
public void setMargin(double margin)
- Sets the margin.
- Overrides:
setMargin
in class XYBarRenderer
- Parameters:
margin
- the margin.
drawItem
public void drawItem(java.awt.Graphics2D g2,
XYItemRendererState state,
java.awt.geom.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. This method
is mostly copied from the superclass, the change is that in the
calculated space for a singe bar we draw bars for each series next to
each other. The width of each bar is the available width divided by
the number of series. Bars for each series are drawn in order left to
right.
- Specified by:
drawItem
in interface XYItemRenderer
- Overrides:
drawItem
in class XYBarRenderer
- 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.item
- the item index.crosshairState
- crosshair information for the plot (null
permitted).pass
- the pass index.
clone
public java.lang.Object clone()
throws java.lang.CloneNotSupportedException
- Returns a clone of the renderer.
- Overrides:
clone
in class XYBarRenderer
- Returns:
- A clone.
- Throws:
java.lang.CloneNotSupportedException
- if the renderer cannot be cloned.
