Java Source Code / Java Documentation » Chart » jfreechart » org.jfree.chart.renderer.xy   Source Cross Reference   Class Diagram   Java Document (Java Doc)   org.jfree.chart.renderer.xy.AbstractXYItemRenderer    org.jfree.chart.renderer.xy.XYBarRenderer       org.jfree.chart.renderer.xy.ClusteredXYBarRenderer ClusteredXYBarRenderer public class ClusteredXYBarRenderer extends XYBarRenderer implements Cloneable,PublicCloneable,Serializable(Code) 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. Constructor Summary public   ClusteredXYBarRenderer()      Default constructor. public   ClusteredXYBarRenderer(double margin, boolean centerBarAtStartValue)      Constructs a new XY clustered bar renderer. Method Summary public  Object clone()      Returns a clone of the renderer. 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. public  boolean equals(Object obj)      Tests this renderer for equality with an arbitrary object, returning true if obj is a ClusteredXYBarRenderer with the same settings as this renderer, and false otherwise. Parameters:   obj - the object (null permitted). public  Range findDomainBounds(XYDataset dataset)      Returns the x-value bounds for the specified dataset. Parameters:   dataset - the dataset (null permitted). protected  Range findDomainBoundsWithOffset(IntervalXYDataset dataset)      Iterates over the items in an IntervalXYDataset to find the range of x-values including the interval OFFSET so that it centers the interval around the start value. Constructor Detail ClusteredXYBarRenderer public ClusteredXYBarRenderer()(Code) Default constructor. Bar margin is set to 0.0. ClusteredXYBarRenderer public ClusteredXYBarRenderer(double margin, boolean centerBarAtStartValue)(Code) Constructs a new XY clustered bar renderer. Parameters:   margin - the percentage amount to trim from the width of each bar. Parameters:   centerBarAtStartValue - if true, bars will be centered on the start of the time period. Method Detail clone public Object clone() throws CloneNotSupportedException(Code) Returns a clone of the renderer. 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)(Code) 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. Parameters:   g2 - the graphics device. Parameters:   state - the renderer state. Parameters:   dataArea - the area within which the plot is being drawn. Parameters:   info - collects information about the drawing. Parameters:   plot - the plot (can be used to obtain standard color information etc). Parameters:   domainAxis - the domain axis. Parameters:   rangeAxis - the range axis. Parameters:   dataset - the dataset. Parameters:   series - the series index. Parameters:   item - the item index. Parameters:   crosshairState - crosshair information for the plot (null permitted). Parameters:   pass - the pass index. equals public boolean equals(Object obj)(Code) Tests this renderer for equality with an arbitrary object, returning true if obj is a ClusteredXYBarRenderer with the same settings as this renderer, and false otherwise. Parameters:   obj - the object (null permitted). A boolean. findDomainBounds public Range findDomainBounds(XYDataset dataset)(Code) Returns the x-value bounds for the specified dataset. Parameters:   dataset - the dataset (null permitted). The bounds (possibly null). findDomainBoundsWithOffset protected Range findDomainBoundsWithOffset(IntervalXYDataset dataset)(Code) Iterates over the items in an IntervalXYDataset to find the range of x-values including the interval OFFSET so that it centers the interval around the start value. Parameters:   dataset - the dataset (null not permitted). The range (possibly null).
