public class PointPainterVerticalBar extends APointPainter<PointPainterVerticalBar>
Bars are placed around the x value to render: the middle of the bar in x dimension is the exact x value.
Constructor and Description |
---|
PointPainterVerticalBar(Chart2D chart)
Creates an instance with a default bar width size of 4.
|
PointPainterVerticalBar(int barWidth,
Chart2D chart)
Creates an instance with the bar width.

int |
hashCode() |
boolean |
isAdditionalSpaceRequiredX()
Return true if this point painter needs more space in x dimension than
TracePoint2D.getX() . |
boolean |
isAdditionalSpaceRequiredY()
Return true if this point painter needs more space in y dimension than
TracePoint2D.getY() . |
boolean |
isPixelTransformationNeededX()
Return true if rendering in x dimension requires a transformation from
pixel to value domain.
|
boolean |
isPixelTransformationNeededY()
Return true if rendering in y dimension requires a transformation from
pixel to value domain.
