Field Detail

serialVersionUID

private static final long serialVersionUID

For serialization.

See Also:

Constant Field Values

roundXCoordinates

private boolean roundXCoordinates

This flag controls whether or not the x-coordinates (in Java2D space) are rounded to integers. When set to true, this can avoid the vertical striping that anti-aliasing can generate. However, the rounding may not be appropriate for output in high resolution formats (for example, vector graphics formats such as SVG and PDF).

Since:

1.0.3

Constructor Detail

StackedXYAreaRenderer2

public StackedXYAreaRenderer2()

Creates a new renderer.

StackedXYAreaRenderer2

public StackedXYAreaRenderer2(XYToolTipGenerator labelGenerator,
                              XYURLGenerator urlGenerator)

Constructs a new renderer.

Parameters:

labelGenerator - the tool tip generator to use. null is none.

urlGenerator - the URL generator (null permitted).

Method Detail

getRoundXCoordinates

public boolean getRoundXCoordinates()

Returns the flag that controls whether or not the x-coordinates (in Java2D space) are rounded to integer values.

Returns:

The flag.

Since:

1.0.4

See Also:

setRoundXCoordinates(boolean)

setRoundXCoordinates

public void setRoundXCoordinates(boolean round)

Sets the flag that controls whether or not the x-coordinates (in Java2D space) are rounded to integer values, and sends a RendererChangeEvent to all registered listeners.

Parameters:

round - the new flag value.

Since:

1.0.4

getRoundXCoordinates()

findRangeBounds

public Range findRangeBounds(XYDataset dataset)

Returns the range of values the renderer requires to display all the items from the specified dataset.

stack2 - the second stack pair.

Returns:

A pair of average stack values.

equals

public boolean equals(java.lang.Object obj)

Tests this renderer for equality with an arbitrary object.

Overrides:

equals in class XYAreaRenderer2

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
