      • draw

        public void draw​(java.awt.Graphics2D g2,
                         XYPlot plot,
                         java.awt.geom.Rectangle2D dataArea,

        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 - if supplied, this info object will be populated with entity information.
