XYDrawableAnnotation

public XYDrawableAnnotation(double x,
double y,
double width,
double height,
Drawable drawable)

Creates a new annotation to be displayed within the given area.

Parameters:

x - the x-coordinate for the area.

y - the y-coordinate for the area.

width - the width of the area.

height - the height of the area.

drawable - the drawable object (null not permitted).

XYDrawableAnnotation

public XYDrawableAnnotation(double x,
double y,
double displayWidth,
double displayHeight,
double drawScaleFactor,
Drawable drawable)

Creates a new annotation to be displayed within the given area. If you specify a drawScaleFactor of 2.0, the drawable will be drawn at twice the requested display size then scaled down to fit the space.

Parameters:

x - the x-coordinate for the area.

y - the y-coordinate for the area.

displayWidth - the width of the area.

displayHeight - the height of the area.

drawScaleFactor - the scaling factor for drawing.

drawable - the drawable object (null not permitted).

Method Details

draw

public void draw(Graphics2D g2,
XYPlot plot,
Rectangle2D dataArea,
ValueAxis domainAxis,
ValueAxis rangeAxis,
int rendererIndex,
PlotRenderingInfo info)

Draws the annotation.

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

equals

public boolean equals(Object obj)

Tests this annotation for equality with an arbitrary object.

Overrides:

equals in class AbstractXYAnnotation

Parameters:

obj - the object to test against.

Returns:

true or false.

hashCode

public int hashCode()

Returns a hash code.
