info.monitorenter.gui.chart.traces.painters.TracePainterPolyline
- All Implemented Interfaces:
IPointPainter<ATracePainter>
,ITracePainter<ATracePainter>
,Serializable
,Comparable<ATracePainter>
A trace painter that increases performance by summing up all points to render
for a paint iteration (submitted by
paintPoint(int, int, int, int, Graphics, ITracePoint2D)
invocations
between startPaintIteration(Graphics)
and
endPaintIteration(Graphics)
) and only invoking only one polyline
paint for a paint call of the corresponding
Chart2D
.

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.
- Specified by:
paintPoint
in interfaceIPointPainter<ATracePainter>
- Overrides:
paintPoint
in classATracePainter
- 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!- See Also:
