Constructor Detail

PointPainterCandleStick

public PointPainterCandleStick(int width)

Constructor taking the width in pixels.

Parameters:

width - the width of the CandleStick in pixels.

Method Detail

calculateMaxX

public double calculateMaxX(ITracePoint2D point)

Description copied from interface: IPointPainter

Returns the maximum x bound this painter will need to paint the given point.

This is needed because a point's bounds may be exceeded when actually painting it.

Parameters:

point - the point to draw.

Returns:

the maximum x bound this painter will need to paint the given point.

See Also:

IPointPainter.calculateMaxX(info.monitorenter.gui.chart.ITracePoint2D)

calculateMaxY

public double calculateMaxY(ITracePoint2D point)

Description copied from interface: IPointPainter

Returns the maximum y bound this painter will need to paint the given point.

This is needed because a point's bounds may be exceeded when actually painting it.

Parameters:

point - the point to draw.

Returns:

the maximum y bound this painter will need to paint the given point.

See Also:

IPointPainter.calculateMaxY(info.monitorenter.gui.chart.ITracePoint2D)

calculateMinX

public double calculateMinX(ITracePoint2D point)

Description copied from interface: IPointPainter

Returns the minimum x bound this painter will need to paint the given point.

This is needed because a point's bounds may be exceeded when actually painting it.

Parameters:

point - the point to draw.

Returns:

the minimum x bound this painter will need to paint the given point.

See Also:

IPointPainter.calculateMinX(info.monitorenter.gui.chart.ITracePoint2D)

calculateMinY

public double calculateMinY(ITracePoint2D point)

Description copied from interface: IPointPainter

Returns the minimum y bound this painter will need to paint the given point.

This is needed because a point's bounds may be exceeded when actually painting it.

Parameters:

point - the point to draw.

Returns:

the minimum y bound this painter will need to paint the given point.

See Also:

IPointPainter.calculateMinY(info.monitorenter.gui.chart.ITracePoint2D)

endPaintIteration

public void endPaintIteration(Graphics g2d)

Description copied from interface: IPointPainter

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

Specified by:

endPaintIteration in interface IPointPainter<PointPainterCandleStick>

Overrides:

endPaintIteration in class APointPainter<PointPainterCandleStick>

Parameters:

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

See Also:

IPointPainter.endPaintIteration(java.awt.Graphics)

isAdditionalSpaceRequiredX

public boolean isAdditionalSpaceRequiredX()

Description copied from interface: IPointPainter

Return true if this point painter needs more space in x dimension than TracePoint2D.getX().

Returns:

true if this point painter needs more space in x dimension than TracePoint2D.getX().

See Also:

IPointPainter.isAdditionalSpaceRequiredX()

isAdditionalSpaceRequiredY

public boolean isAdditionalSpaceRequiredY()

Description copied from interface: IPointPainter

Return true if this point painter needs more space in y dimension than TracePoint2D.getY().

Returns:

true if this point painter needs more space in y dimension than TracePoint2D.getY().

See Also:

IPointPainter.isAdditionalSpaceRequiredY()

isPixelTransformationNeededX

public boolean isPixelTransformationNeededX()

Description copied from interface: IPointPainter

Return true if rendering in x dimension requires a transformation from pixel to value domain.

If this is the case min-max - search of the trace is much slower (points * 2 * amount of painters).

Returns:

true if rendering in x dimension requires a transformation from pixel to value domain.

See Also:

IPointPainter.isPixelTransformationNeededX()

isPixelTransformationNeededY

public boolean isPixelTransformationNeededY()

Description copied from interface: IPointPainter

Return true if rendering in y dimension requires a transformation from pixel to value domain.

If this is the case min-max - search of the trace is much slower (points * 2 * amount of painters).

Returns:

true if rendering in y dimension requires a transformation from pixel to value domain.

IPointPainter.isPixelTransformationNeededX()

paintPoint

public void paintPoint(int absoluteX,
                       int absoluteY,
                       int nextX,
                       int nextY,
                       Graphics g,
                       ITracePoint2D 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.

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!

startPaintIteration

public void startPaintIteration(Graphics g2d)

Description copied from interface: IPointPainter

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

Specified by:

startPaintIteration in interface IPointPainter<PointPainterCandleStick>

Overrides:

startPaintIteration in class APointPainter<PointPainterCandleStick>

Parameters:

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