Enum Constant Detail
-
EUCLID
public static final Chart2D.PointFinder EUCLID
Uses the Manhattan distance to find the nearest point.This implementation is slower than MANHATTAN but has a search field in form of a circle which is more natural for human eyes.
- See Also:
Chart2D.getNearestPointEuclid(int, int)
-
MANHATTAN
public static final Chart2D.PointFinder MANHATTAN
Uses the Manhattan distance to find the nearest point.This implementation is faster than EUCLID (only subtractions/additions/abs) but has a search field in form of a rhombus which may confuse human eyes.

values
public static Chart2D.PointFinder[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (Chart2D.PointFinder c : Chart2D.PointFinder.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static Chart2D.PointFinder valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
getNearestPoint
public ITracePoint2D getNearestPoint(java.awt.event.MouseEvent me, Chart2D chart)
Default implementation always returns null.- Specified by:
getNearestPoint
in interfaceIPointFinder
- Parameters:
me
- the mouse event over the chart.chart
- to search points within.- Returns:
- e nearest
to the given mouse event's screen coordinates orMouseEvent
null
if no point was found / service is not implemented. - See Also:
