Constructor Detail

PlotRenderingInfo

public PlotRenderingInfo(ChartRenderingInfo owner)

Creates a new instance.

Parameters:

owner - the owner (null permitted).

Method Detail

getOwner

public ChartRenderingInfo getOwner()

Returns the owner (as specified in the constructor).

Returns:

The owner (possibly null).

getPlotArea

public Rectangle2D getPlotArea()

Returns the plot area (in Java2D space).

Returns:

The plot area (possibly null).

See Also:

setPlotArea(Rectangle2D)

setPlotArea

public void setPlotArea(Rectangle2D area)

Sets the plot area.

Parameters:

area - the plot area (in Java2D space, null permitted but discouraged)

See Also:

getPlotArea()

getDataArea

public Rectangle2D getDataArea()

Returns the plot's data area (in Java2D space).

Returns:

The data area (possibly null).

See Also:

setDataArea(Rectangle2D)

setDataArea

public void setDataArea(Rectangle2D area)

Sets the data area.

Parameters:

area - the data area (in Java2D space, null permitted but discouraged).

See Also:

getDataArea()

getSubplotCount

public int getSubplotCount()

Returns the number of subplots (possibly zero).

Returns:

The subplot count.

addSubplotInfo

public void addSubplotInfo(PlotRenderingInfo info)

Adds the info for a subplot.

Parameters:

info - the subplot info.

See Also:

getSubplotInfo(int)

getSubplotInfo

public PlotRenderingInfo getSubplotInfo(int index)

Returns the info for a subplot.

Parameters:

index - the subplot index.

Returns:

The info.

See Also:

addSubplotInfo(PlotRenderingInfo)

getSubplotIndex

public int getSubplotIndex(Point2D source)

Returns the index of the subplot that contains the specified (x, y) point (the "source" point). The source point will usually come from a mouse click on a ChartPanel, and this method is then used to determine the subplot that contains the source point.

Parameters:

source - the source point (in Java2D space, null not permitted).

Returns:

The subplot index (or -1 if no subplot contains source).

equals

public boolean equals(Object obj)

Tests this instance for equality against an arbitrary object.

Overrides:

equals in class Object

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of this object.

Overrides:

clone in class Object

Returns:

A clone.

Throws:

CloneNotSupportedException - if there is a problem cloning.
