Constructor Details

StatisticalBarRenderer

public StatisticalBarRenderer()

Default constructor.

Method Details

getErrorIndicatorPaint

public Paint getErrorIndicatorPaint()

Returns the paint used for the error indicators.

Returns:

The paint used for the error indicators (possibly null).

See Also:

• setErrorIndicatorPaint(Paint)

setErrorIndicatorPaint

public void setErrorIndicatorPaint(Paint paint)

Sets the paint used for the error indicators (if null, the item outline paint is used instead) and sends a RendererChangeEvent to all registered listeners.

Parameters:

paint - the paint (null permitted).

See Also:

• getErrorIndicatorPaint()

getErrorIndicatorStroke

public Stroke getErrorIndicatorStroke()

Returns the stroke used to draw the error indicators. If this is null, the renderer will use the item outline stroke).

Returns:

The stroke (possibly null).

See Also:

• setErrorIndicatorStroke(Stroke)

setErrorIndicatorStroke

public void setErrorIndicatorStroke(Stroke stroke)

Sets the stroke used to draw the error indicators, and sends a RendererChangeEvent to all registered listeners. If you set this to null, the renderer will use the item outline stroke.

Parameters:

stroke - the stroke (null permitted).

See Also:

• getErrorIndicatorStroke()

findRangeBounds

public Range findRangeBounds(CategoryDataset dataset)

Returns the range of values the renderer requires to display all the items from the specified dataset. This takes into account the range between the min/max values, possibly ignoring invisible series.
