Method Detail

• getNearestPoint

  ITracePoint2D getNearestPoint​(int mouseEventX,
                                int mouseEventY,
                                Chart2D chart)

  Returns the nearest ITracePoint2D to the given mouse event's screen coordinates.

  Parameters:

  mouseEventX - the x pixel value relative to the chart (e.g.: MouseEvent.getY()).

  mouseEventY - the y pixel value relative to the chart (e.g.: MouseEvent.getY()).

  chart - to search points within.

  Returns:

  the nearest ITracePoint2D to the given mouse event's screen coordinates.

• getNearestPoint

  ITracePoint2D getNearestPoint​(java.awt.event.MouseEvent me,
                                Chart2D chart)

  Returns the nearest MouseEvent to the given mouse event's screen coordinates or null if no point was found / service is not implemented.

  Simple implementations could use Manhattan distance or Euclid distance.

  Parameters:

  me - the mouse event over the chart.

  chart - to search points within.

  Returns:

  e nearest MouseEvent to the given mouse event's screen coordinates or null if no point was found / service is not implemented.
