Initialization
(nonnull instancetype)	- initWithText:textStyle:
	Initializes a newly allocated text-based CPTAxisLabel object with the provided text and style. More...
(nonnull instancetype)	- initWithContentLayer:
	Initializes a newly allocated CPTAxisLabel object with the provided layer. This is the designated initializer. More...
(nullable instancetype)	- initWithCoder:
	Returns an object initialized from data in a given unarchiver. More...
Layout
(void)	- positionRelativeToViewPoint:forCoordinate:inDirection:
	Positions the axis label relative to the given point. The algorithm for positioning is different when the rotation property is non-zero. When zero, the anchor point is positioned along the closest side of the label. When non-zero, the anchor point is left at the center. This has consequences for the value taken by the offset. More...
(void)	- positionBetweenViewPoint:andViewPoint:forCoordinate:inDirection:
	Positions the axis label between two given points. More...
Comparison
(BOOL)	- isEqual: [implementation]
	Returns a boolean value that indicates whether the received is equal to the given object. Axis labels are equal if they have the same tickLocation. More...

Detailed Description

An axis label.

The label can be text-based or can be the content of any CPTLayer provided by the user.

Method Documentation

initWithCoder:

- (nullable instancetype) initWithCoder:

(nonnull NSCoder *)

coder

Returns an object initialized from data in a given unarchiver.

Parameters

coder

An unarchiver object.

Returns

An object initialized from data in a given unarchiver.

initWithContentLayer:

- (nonnull instancetype) initWithContentLayer:

(nonnull CPTLayer *)

layer

Initializes a newly allocated CPTAxisLabel object with the provided layer. This is the designated initializer.

Parameters

layer

The label content.

Returns

The initialized CPTAxisLabel object.

initWithText:textStyle:

- (nonnull instancetype) initWithText:		(nullable NSString *)	newText
textStyle:		(nullable CPTTextStyle *)	newStyle

Initializes a newly allocated text-based CPTAxisLabel object with the provided text and style.

Parameters

newText	The label text.
newStyle	The text style for the label.

Returns

The initialized CPTAxisLabel object.

isEqual:

- (BOOL) isEqual: (nullable id)  object

implementation

Returns a boolean value that indicates whether the received is equal to the given object. Axis labels are equal if they have the same tickLocation.

Parameters

object

The object to be compared with the receiver.

Returns

YES if object is equal to the receiver, NO otherwise.

Reimplemented in CPTAxisTitle.

positionBetweenViewPoint:andViewPoint:forCoordinate:inDirection:

- (void) positionBetweenViewPoint:		(CGPoint)	firstPoint
andViewPoint:		(CGPoint)	secondPoint
forCoordinate:		(CPTCoordinate)	coordinate
inDirection:		(CPTSign)	direction

Positions the axis label between two given points.

Parameters

firstPoint	The first view point.
secondPoint	The second view point.
coordinate	The axis coordinate.
direction	The offset direction.

positionRelativeToViewPoint:forCoordinate:inDirection:

- (void) positionRelativeToViewPoint:		(CGPoint)	point
forCoordinate:		(CPTCoordinate)	coordinate
inDirection:		(CPTSign)	direction

Positions the axis label relative to the given point. The algorithm for positioning is different when the rotation property is non-zero. When zero, the anchor point is positioned along the closest side of the label. When non-zero, the anchor point is left at the center. This has consequences for the value taken by the offset.

Parameters

point	The view point.
coordinate	The coordinate in which the label is being position. Orthogonal to the axis coordinate.
direction	The offset direction.

Property Documentation

alignment

- (CPTAlignment) alignment

readwritenonatomicassign

The alignment of the axis label with respect to the tick mark.

contentLayer

- (nullable CPTLayer *) contentLayer

readwritenonatomicstrong

The label content.

offset

- (CGFloat) offset

readwritenonatomicassign

The offset distance between the axis and label.

rotation

- (CGFloat) rotation

readwritenonatomicassign

The rotation of the label in radians.

tickLocation

- (nonnull NSNumber *) tickLocation

readwritenonatomicstrong

The data coordinate of the tick location.
