Method Detail

draw

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

                 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)

Overrides:

equals in class AbstractXYAnnotation

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

hashCode

public int hashCode()
