All Implemented Interfaces:

IPointPainter, ITracePainter, Serializable, Comparable

public class TracePainterVerticalBar
extends ATracePainter

Renders traces by painting a bar with choosable width for each TracePoint2D to show.

Bars are placed around the x value to render: the middle of the bar in x dimension is the exact x value.

Constructor Detail

TracePainterVerticalBar

public TracePainterVerticalBar(Chart2D chart)

Creates an instance with a default bar width size of 4.

Parameters:

chart - needed for bound information.

TracePainterVerticalBar

public TracePainterVerticalBar(int barWidth,
                               Chart2D chart)

Creates an instance with the bar width.

Parameters:

barWidth - the bar width in pixel to use.

chart - needed for bound information.

Method Detail

endPaintIteration

public void endPaintIteration(Graphics2D g2d)

Description copied from interface: ITracePainter

Invoked to inform implementations that a paint iteration ends for the corresponding ITrace2D.

Specified by:

endPaintIteration in interface ITracePainter

Overrides:

endPaintIteration in class ATracePainter

Parameters:

g2d - provided in case pending paint operations have to be performed.

See Also:

ITracePainter.endPaintIteration(java.awt.Graphics2D)

getBarWidth

public int getBarWidth()

Returns the diameter of the discs to paint in pixel.

Returns:

the diameter of the discs to paint in pixel.

paintPoint

public void paintPoint(int absoluteX,
                       int absoluteY,
                       int nextX,
                       int nextY,
                       Graphics2D g,
                       TracePoint2D original)

Description copied from interface: IPointPainter

Paint the point given by absolute coordinates on the given graphic context.

The next coordinates are also provided to allow to check how much distance is available for the graphic representation of the current point.

Note that by contract the TracePoint2D argument is only guaranteed to be non-null in case the instance is used as a painter for ITracePainter subtypes. If you plan to use your implementation also for a subcomponent of an IErrorBarPainter (e.g. IErrorBarPainter.setConnectionPainter(IPointPainter)) then you have to implement "null - safe" for that argument.

Specified by:

paintPoint in interface IPointPainter

Overrides:

paintPoint in class ATracePainter

Parameters:

absoluteX - the ready to use x value for the point to paint.

absoluteY - the ready to use y value for the point to paint.

nextX - the ready to use next x value for the point to paint.

nextY - the ready to use next y value for the point to paint.

g - the graphic context to paint on.

original - just for information, for painting this should be irrelevant and it should not be changed too!

setBarWidth

public void setBarWidth(int barWidth)

Sets the width of the bars to paint in pixel.

Parameters:

barWidth - the width of the bars to paint in pixel.
