Class 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).

public XYPolygonAnnotation(double[] polygon,
                           Stroke stroke,
                           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).

public XYPolygonAnnotation(double[] polygon,
                           Stroke stroke,
                           Paint outlinePaint,
                           Paint fillPaint)

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:

polygon - the coordinates of the polygon's vertices (null not permitted).

stroke - the shape stroke (null permitted).

outlinePaint - the shape color (null permitted).

fillPaint - the paint used to fill the shape (null permitted).

public Object clone()
            throws CloneNotSupportedException

Returns a clone.

Returns:

A clone.

public void draw(Graphics2D g2,
                 XYPlot plot,
                 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

Overrides:

draw in interface 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.

public boolean equals(Object obj)

Tests this annotation for equality with an arbitrary object.

Overrides:

equals in interface AbstractXYAnnotation

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

public Paint getFillPaint()

Returns the fill paint.

Returns:

The fill paint (possibly null).

Since:

1.0.2

public Paint getOutlinePaint()

Returns the outline paint.

Returns:

The outline paint (possibly null).

Since:

1.0.2

public Stroke getOutlineStroke()

Returns the outline stroke.

Returns:

The outline stroke (possibly null).

Since:

1.0.2

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

public int hashCode()

Returns a hash code for this instance.

Overrides:

hashCode in interface AbstractXYAnnotation

Returns:

A hash code.
