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.

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.

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

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.isPixelTransformationNeededY()

paintPoint

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

Paints a line from current to next 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.

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