Class ErrorBarPainter

java.lang.Object
  info.monitorenter.gui.chart.errorbars.ErrorBarPainter

All Implemented Interfaces:

IErrorBarPainter, Serializable

Direct Known Subclasses:

ErrorBarPainterLine

public class ErrorBarPainter
extends Object
implements IErrorBarPainter

Implementation of an error bar painter that allows configuration of the way the connection, start point and end point of an error bar is painted by the use of IPointPainter.

Property change events are fired as described in method IErrorBarPainter.addPropertyChangeListener(String, PropertyChangeListener). Note that adding property change listeners to the nested access facades of type IErrorBarPainter.ISegment accessible via getXXXSegment() methods will fire the corresponding events for listeners of this instance (as they delegate the calls) while they fire events for properties defined in IErrorBarPainter.ISegment too. If you register for events of this instance and for the retrieved segments you will receive two PropertyChangeListener.propertyChange(java.beans.PropertyChangeEvent) for the same value changed.

public ErrorBarPainter()

Creates an instance that by default will not render any error bar.

It then has to be configured with the remaining methods as desired.

Method Detail

addPropertyChangeListener

public final void addPropertyChangeListener(String propertyName,
                                            PropertyChangeListener listener)

Description copied from interface: IErrorBarPainter

Registers a property change listener that will be informed about changes of the property identified by the given propertyName.

PropertyChangeEvents

PropertyChangeListener instances may be added via Container.addPropertyChangeListener(java.lang.String, java.beans.PropertyChangeListener). They inherit the properties to listen from Container.addPropertyChangeListener(java.lang.String, java.beans.PropertyChangeListener). Additionally more PropertyChangeEvents should be triggered (contract for implementation!).

Property Change events

The following PropertyChangeEvent instances will be fired to registered PropertyChangeListener instances.

getPropertyName()	getSource()	getOldValue()	getNewValue()	comment
IErrorBarPainter.PROPERTY_ENDPOINT	IErrorBarPainter that changed.	IPointPainter.	IPointPainter.	Note that null as the old value indicates a new painter. Null as the new value is valid and means that the end point rendering is turned off.
IErrorBarPainter.PROPERTY_STARTPOINT	IErrorBarPainter that changed.	IPointPainter.	IPointPainter.	Note that null as the old value indicates a new painter. Null as the new value is valid and means that the start point rendering is turned off.
IErrorBarPainter.PROPERTY_CONNECTION	IErrorBarPainter that changed.	IPointPainter.	IPointPainter.	Note that null as the old value indicates a new painter. Null as the new value is valid and means that the connection segment point rendering is turned off.
IErrorBarPainter.PROPERTY_ENDPOINT_COLOR	IErrorBarPainter that changed.	Color.	Color.	Note that null as the old value indicates a new color different from the default. Null as the new value is valid and means that the end point color is switched to default.
IErrorBarPainter.PROPERTY_STARTPOINT_COLOR	IErrorBarPainter that changed.	Color.	Color.	Note that null as the old value indicates a new color different from the default. Null as the new value is valid and means that the start point color is switched to default.
IErrorBarPainter.PROPERTY_CONNECTION_COLOR	IErrorBarPainter that changed.	Color.	Color.	Note that null as the old value indicates a new color different from the default. Null as the new value is valid and means that the connection segment color is switched to default.

setConnectionColor

public final void setConnectionColor(Color connectionColor)

Description copied from interface: IErrorBarPainter

Sets the color for the connection segment.

If this is not used or null is provided, the color of the corresponding trace will be used.

Specified by:

setConnectionColor in interface IErrorBarPainter

Parameters:

connectionColor - The connection segment color to set.

See Also:

IErrorBarPainter.setConnectionColor(java.awt.Color)

setEndPointColor

public final void setEndPointColor(Color endPointColor)

Description copied from interface: IErrorBarPainter

Sets the color for the end point.

If this is not used or null is provided, the color of the corresponding trace will be used.

Specified by:

setEndPointColor in interface IErrorBarPainter

Parameters:

endPointColor - The end point color to set.

IErrorBarPainter.setEndPointColor(java.awt.Color)

setEndPointPainter

public final void setEndPointPainter(IPointPainter endPointPainter)

Description copied from interface: IErrorBarPainter

Sets the painter for the end point of the error bar.

Note that the choice for the right point painter has to be taken with care: It is senseless to use an implementation that interconnects both coordinates given to IPointPainter.paintPoint(int, int, int, int, Graphics2D, TracePoint2D).

Choosing a PointPainterLine will have the same visual effect as setting such an instance for the connection segment painter.

Specified by:

setEndPointPainter in interface IErrorBarPainter

Parameters:

endPointPainter - The end point painter to set.

See Also:

IErrorBarPainter.setEndPointPainter(info.monitorenter.gui.chart.IPointPainter)

setConnectionPainter

public final void setConnectionPainter(IPointPainter connectionPainter)

Description copied from interface: IErrorBarPainter

Note that the choice for the right point painter has to be taken with care: It is senseless to use an implementation that does not interconnect both coordinates given to IPointPainter.paintPoint(int, int, int, int, Graphics2D, TracePoint2D).

Choosing a PointPainterLine will have the same visual effect as setting such an instance for the start point painter.

Currently the only senseful choice is the PointPainterLine or null (to make the connection segment invisible). But the interface is open enough to use implementations that would paint interpolated dots, discs, squares,... whatever you think of (contribute!).

Specified by:

setConnectionPainter in interface IErrorBarPainter

Parameters:

connectionPainter - The connection segmentPainter to set.

See Also:

IErrorBarPainter.setConnectionPainter(info.monitorenter.gui.chart.IPointPainter)

setStartPointColor

public final void setStartPointColor(Color startPointColor)

Description copied from interface: IErrorBarPainter

Sets the color for the start point.

If this is not used or null is provided, the color of the corresponding trace will be used.

Specified by:

setStartPointColor in interface IErrorBarPainter

Parameters:

startPointColor - The start point color to set.

See Also:

IErrorBarPainter.setStartPointColor(java.awt.Color)

setStartPointPainter

public final void setStartPointPainter(IPointPainter startPointPainter)

Description copied from interface: IErrorBarPainter

Note that the choice for the right point painter has to be taken with care: It is senseless to use an implementation that interconnects both coordinates given to IPointPainter.paintPoint(int, int, int, int, Graphics2D, TracePoint2D).

Choosing a PointPainterLine will have the same visual effect as setting such an instance for the connection segment painter.
