All Implemented Interfaces:

IPointPainter<ATracePainter>, ITracePainter<ATracePainter>, java.io.Serializable, java.lang.Comparable<ATracePainter>
```
public class TracePainterPolyline
extends 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.

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

                       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 interface IPointPainter<ATracePainter>
    
    Overrides:
    
    paintPoint in class ATracePainter
    
    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!
