Class XYPolygonAnnotation

    • Constructor Detail

      • XYPolygonAnnotation

        public XYPolygonAnnotation​(double[] polygon)
        Creates a new annotation (where, by default, the polygon is drawn with a black outline). The array of polygon coordinates must contain an even number of coordinates (each pair is an (x, y) location on the plot) and the last point is automatically joined back to the first point.
        Parameters:
        polygon - the coordinates of the polygon's vertices (null not permitted).
      • XYPolygonAnnotation

        public XYPolygonAnnotation​(double[] polygon,
                                   java.awt.Stroke stroke,
                                   java.awt.Paint outlinePaint)
        Creates a new annotation where the box is drawn as an outline using the specified stroke and outlinePaint. The array of polygon coordinates must contain an even number of coordinates (each pair is an (x, y) location on the plot) and the last point is automatically joined back to the first point.
        Parameters:
        polygon - the coordinates of the polygon's vertices (null not permitted).
        stroke - the shape stroke (null permitted).
        outlinePaint - the shape color (null permitted).

        Creates a new annotation. The array of polygon coordinates must contain an even number of coordinates (each pair is an (x, y) location on the plot) and the last point is automatically joined back to the first point.
        Parameters:

        stroke - the shape stroke (null permitted).
        outlinePaint - the shape color (null permitted).
        fillPaint - the paint used to fill the shape (null permitted).
    • Method Detail

      • getPolygonCoordinates

        public double[] getPolygonCoordinates()
        Returns the coordinates of the polygon's vertices. The returned array is a copy, so it is safe to modify without altering the annotation's state.
        Returns:
        The coordinates of the polygon's vertices.
        Since:
        1.0.2
      • getFillPaint

        public java.awt.Paint getFillPaint()
        Returns the fill paint.
        Returns:
        The fill paint (possibly null).
        Since:
        1.0.2
      • getOutlineStroke

        public java.awt.Stroke getOutlineStroke()
        Returns the outline stroke.
        Returns:
        The outline stroke (possibly null).
        Since:
        1.0.2
      • getOutlinePaint

        public java.awt.Paint getOutlinePaint()
        Returns the outline paint.
        Returns:
        The outline paint (possibly null).
        Since:
        1.0.2
      • draw

        public void draw​(java.awt.Graphics2D g2,
                         XYPlot plot,
                         java.awt.geom.Rectangle2D dataArea,
                         ValueAxis domainAxis,
                         ValueAxis rangeAxis,
                         int rendererIndex,
                         PlotRenderingInfo info)
        Draws the annotation. This method is usually called by the XYPlot class, you shouldn't need to call it directly.
        Specified by:
        draw in interface XYAnnotation
        Specified by:
        draw in class AbstractXYAnnotation
        Parameters:
        g2 - the graphics device.
        plot - the plot.
        dataArea - the data area.
        domainAxis - the domain axis.
        rangeAxis - the range axis.
        rendererIndex - the renderer index.
        info - the plot rendering info.
      • equals

        public boolean equals​(java.lang.Object obj)
        Tests this annotation for equality with an arbitrary object.
        Overrides:
        equals in class AbstractXYAnnotation
        Parameters:
        obj - the object (null permitted).
        Returns:
        A boolean.
      • clone

        public java.lang.Object clone()
                               throws java.lang.CloneNotSupportedException
        Returns a clone.
        Specified by:
        clone in interface org.jfree.util.PublicCloneable
        Overrides:
        clone in class AbstractAnnotation
        Returns:
        A clone.
        Throws:
        java.lang.CloneNotSupportedException - not thrown by this class, but may be by subclasses.
