Positions a content layer relative to an anchor point in a reference layer.
Layer annotations are positioned relative to a reference layer. This allows the annotation content layer to move with changes in the reference layer. This is useful for applications such as titles attached to an edge of the reference layer.
| - (nonnull instancetype) initWithAnchorLayer: | (nonnull CPTLayer *) | newAnchorLayer |
Initializes a newly allocated CPTLayerAnnotation object with the provided reference layer.
This is the designated initializer. The initialized layer will be anchored to CPTRectAnchorTop by default.
| newAnchorLayer | The reference layer. Must be non-nil. |
| - (nullable instancetype) initWithCoder: | (nonnull NSCoder *) | coder |
Returns an object initialized from data in a given unarchiver.
| coder | An unarchiver object. |
Reimplemented from CPTAnnotation.

The anchor position for the annotation.
|
readwritenonatomicstrong |
The constraints used to position the content layer relative to the reference layer in the x-direction. Setting the rectAnchor resets the constraints.
