addAdditionalPointPainter
Adds a point painter that additionally (to the pointer painters of the trace (
)) paint this point.ITrace2D.getTracePainters()
No clone will be taken. Outside modifications of the argument later on will also affect this instances state!
Caution! This is a low level mechanism that is also used by the highlighting mechanism. It is being utilized by the
which will use some mouse motion listener to remove outdated highlighters and add highlighters to the new point in focus by taking the highlighter configured in the trace.Chart2D.enablePointHighlighting(boolean)
So to use point highlighting for traces you should not re-program it at this level but just use
andITrace2D.addPointHighlighter(IPointPainter)
Chart2D.enablePointHighlighting(boolean)
.- Parameters:
pointPainter
- a point painter that will additionally (to the trace painter of the chart) paint this point.- Returns:
- true if this point painter was accepted (not contained before by
the means of
Comparable.compareTo(Object)
-
removeAdditionalPointPainter
Removes a point painter that additionally (to the pointer painters of the trace (
)) paint this point.ITrace2D.getTracePainters()
- Parameters:
pointPainter
- a point painter that currently is used to additionally (to the trace painter of the chart) paint this point.- Returns:
- true if this point painter was removed (contained before by the
means of
Comparable.compareTo(Object)
-
removeAllAdditionalPointPainters
Set<IPointPainter<?>> removeAllAdditionalPointPainters()Removes all point painters that additionally (to the pointer painters of the trace (
)) paint this point.ITrace2D.getTracePainters()
- Returns:
- all instances that were used before this call.
-
clone
Object clone()Returns a cloned instance (deep copy).- Returns:
- a cloned instance (deep copy)
-
getAdditionalPointPainters
Set<IPointPainter<?>> getAdditionalPointPainters()Returns the point painter that additionally (to the trace painter of the chart) paint this point.The original list is returned so painters may be added or removed (even all painters may be cleared).
- Returns:
- the point painters that additionally (to the trace painter of the chart) paint this point.
-
getEuclidDistance
double getEuclidDistance(double xNormalized, double yNormalized) Returns the Euclid distance of this point's normalized values (
) to the given normalized coordinates.getScaledX()
,getScaledY()
- Parameters:
