      • 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 name
        java.lang.NullPointerException - if the argument is null
