public class TracePainterFill extends ATracePainter
Additionally it increases performance by summing up all points to render for
a paint iteration (submitted by
paintPoint(int, int, int, int, Graphics, ITracePoint2D)
between
startPaintIteration(Graphics)
and
endPaintIteration(Graphics)
) and only invoking only one polygon
paint for a paint call of the corresponding
Chart2D
.

ITracePainter
This only has to be implemented by painters that collect several points of
IPointPainter.paintPoint(int, int, int, int, Graphics, ITracePoint2D)
to draw them as polygons (e.g.:
Graphics.drawPolyline(int[], int[], int)
).
