The area * returned can be used as the tooltip region. * 23-Jan-2002 : Added DrawInfo parameter to drawItem() method (DG); * 28-Mar-2002 : Added a property change listener mechanism. Now renderers do * not have to be immutable (DG); * 04-Apr-2002 : Added the initialise() method (DG); * 09-Apr-2002 : Removed the translated zero from the drawItem method, it can * be calculated inside the initialise method if it is required. * Added a new getToolTipGenerator() method. Changed the return * type for drawItem() to void (DG); * 24-May-2002 : Added ChartRenderingInfo the initialise method API (DG); * 25-Jun-2002 : Removed redundant import (DG); * 20-Aug-2002 : Added get/setURLGenerator methods to interface (DG); * 02-Oct-2002 : Fixed errors reported by Checkstyle (DG); * 18-Nov-2002 : Added methods for drawing grid lines (DG); * 17-Jan-2003 : Moved plot classes into a separate package (DG); * 27-Jan-2003 : Added shape lookup table (DG); * 05-Jun-2003 : Added domain and range grid bands (sponsored by Focus Computer * Services Ltd) (DG); * 27-Jul-2003 : Added getRangeType() to support stacked XY area charts (RA); * 16-Sep-2003 : Changed ChartRenderingInfo --> PlotRenderingInfo (DG); * 25-Feb-2004 : Replaced CrosshairInfo with CrosshairState. Renamed * XYToolTipGenerator --> XYItemLabelGenerator (DG); * 26-Feb-2004 : Added lots of new methods (DG); * 30-Apr-2004 : Added getRangeExtent() method (DG); * 06-May-2004 : Added methods for controlling item label visibility (DG); * 13-May-2004 : Removed property change listener mechanism (DG); * 18-May-2004 : Added item label font and paint methods (DG); * 10-Sep-2004 : Removed redundant getRangeType() method (DG); * 06-Oct-2004 : Replaced getRangeExtent() with findRangeBounds() and added * findDomainBounds (DG); * 23-Nov-2004 : Changed drawRangeGridLine() --> drawRangeLine() (DG); * 07-Jan-2005 : Removed deprecated method (DG); * 24-Feb-2005 : Now extends LegendItemSource (DG); * 20-Apr-2005 : Renamed XYLabelGenerator --> XYItemLabelGenerator (DG); * ------------- JFREECHART 1.0.x --------------------------------------------- * 19-Apr-2007 : Deprecated seriesVisible and seriesVisibleInLegend flags (DG); * 20-Apr-2007 : Deprecated paint, fillPaint, outlinePaint, stroke, * outlineStroke, shape, itemLabelsVisible, itemLabelFont, * itemLabelPaint, positiveItemLabelPosition, * negativeItemLabelPosition and createEntities override * fields (DG); * */ package org.jfree.chart.renderer.xy; import java.awt.Font; import java.awt.Graphics2D; import java.awt.Paint; import java.awt.Shape; import java.awt.Stroke; import java.awt.geom.Rectangle2D; import org.jfree.chart.LegendItem; import org.jfree.chart.LegendItemSource; import org.jfree.chart.annotations.XYAnnotation; import org.jfree.chart.axis.ValueAxis; import org.jfree.chart.event.RendererChangeEvent; import org.jfree.chart.event.RendererChangeListener; import org.jfree.chart.labels.ItemLabelPosition; import org.jfree.chart.labels.XYItemLabelGenerator; import org.jfree.chart.labels.XYSeriesLabelGenerator; import org.jfree.chart.labels.XYToolTipGenerator; import org.jfree.chart.plot.CrosshairState; import org.jfree.chart.plot.Marker; import org.jfree.chart.plot.PlotRenderingInfo; import org.jfree.chart.plot.XYPlot; import org.jfree.chart.urls.XYURLGenerator; import org.jfree.data.Range; import org.jfree.data.xy.XYDataset; import org.jfree.ui.Layer; /** * Interface for rendering the visual representation of a single (x, y) item on * an {@link XYPlot}. * <p> * To support cloning charts, it is recommended that renderers implement both * the {@link Cloneable} and <code>PublicCloneable interfaces. */ public interface XYItemRenderer extends LegendItemSource { /** * Returns the plot that this renderer has been assigned to. * * @return The plot. */ public XYPlot getPlot(); /** * Sets the plot that this renderer is assigned to.
