Detailed Description

Positions a content layer relative to some anchor point in a plot space.

Plot space annotations are positioned relative to a plot space. This allows the annotation content layer to move with the plot when the plot space changes. This is useful for applications such as labels attached to specific data points on a plot.

Method Documentation

◆ initWithCoder:

- (nullable instancetype) initWithCoder: (nonnull NSCoder *)  coder

Returns an object initialized from data in a given unarchiver.

Parameters
coderAn unarchiver object.
Returns
An object initialized from data in a given unarchiver.

Reimplemented from CPTAnnotation.

◆ initWithPlotSpace:anchorPlotPoint:

- (nonnull instancetype) initWithPlotSpace: (nonnull CPTPlotSpace *)  newPlotSpace
anchorPlotPoint: (nullable CPTNumberArray *)  newPlotPoint 

Initializes a newly allocated CPTPlotSpaceAnnotation object.

This is the designated initializer. The initialized layer will be anchored to a point in plot coordinates.

Parameters
newPlotSpaceThe plot space which the anchor is defined in. Must be non-nil.
newPlotPointAn array of NSDecimalNumber objects giving the anchor plot coordinates.
Returns
The initialized CPTPlotSpaceAnnotation object.

Property Documentation

◆ anchorPlotPoint

- (nullable CPTNumberArray *) anchorPlotPoint
readwritenonatomiccopy

An array of NSDecimalNumber objects giving the anchor plot coordinates.

◆ plotSpace

- (nonnull CPTPlotSpace *) plotSpace
readnonatomicassign

The plot space which the anchor is defined in.
