Detailed Description

A container layer for annotations.

Annotations (CPTAnnotation) can be added to and removed from an annotation layer. The host layer automatically handles the annotation layout.

Method Documentation

◆ addAnnotation:

- (void) addAnnotation: (nullable CPTAnnotation *) annotation

Adds an annotation to the receiver.

◆ initWithFrame:

- (nonnull instancetype) initWithFrame: (CGRect) newFrame

implementation

Initializes a newly allocated CPTAnnotationHostLayer object with the provided frame rectangle.

This is the designated initializer. The initialized layer will have an empty annotations array.

Parameters

newFrame The frame rectangle.

Returns: The initialized CPTAnnotationHostLayer object.

Reimplemented from CPTLayer.

Reimplemented in CPTPieChart, CPTPlot, CPTTradingRangePlot, CPTRangePlot, CPTBarPlot, CPTScatterPlot, CPTGraph, CPTLegend, CPTPlotArea, CPTBorderedLayer, CPTPlotAreaFrame, and CPTXYGraph.

◆ pointingDeviceCancelledEvent:

- (BOOL) pointingDeviceCancelledEvent: (nonnull CPTNativeEvent *) event

implementation

Informs the receiver that tracking of touches has been cancelled for any reason.

The event is passed in turn to each annotation layer. If any layer handles the event, subsequent layers are not notified and this method immediately returns YES.

Parameters

event The OS event.

Returns: Whether the event was handled or not.

Reimplemented from <CPTResponder>.

Reimplemented in CPTGraph, and CPTPlotAreaFrame.

◆ pointingDeviceDownEvent:atPoint:

- (BOOL) pointingDeviceDownEvent:	(nonnull CPTNativeEvent *)	event
atPoint:	(CGPoint)	interactionPoint

implementation

Informs the receiver that the user has touched the screen.

The event is passed in turn to each annotation layer that contains the interaction point. If any layer handles the event, subsequent layers are not notified and this method immediately returns YES.

Parameters

event	The OS event.
interactionPoint	The coordinates of the interaction.

Returns: Whether the event was handled or not.

Reimplemented from <CPTResponder>.

Reimplemented in CPTPieChart, CPTPlot, CPTTradingRangePlot, CPTRangePlot, CPTBarPlot, CPTScatterPlot, CPTGraph, CPTLegend, CPTPlotArea, and CPTPlotAreaFrame.

◆ pointingDeviceDraggedEvent:atPoint:

- (BOOL) pointingDeviceDraggedEvent:	(nonnull CPTNativeEvent *)	event
atPoint:	(CGPoint)	interactionPoint

implementation

Informs the receiver that the user has moved their finger while touching the screen.

The event is passed in turn to each annotation layer that contains the interaction point. If any layer handles the event, subsequent layers are not notified and this method immediately returns YES.

Parameters

event	The OS event.
interactionPoint	The coordinates of the interaction.

Returns: Whether the event was handled or not.

Reimplemented from <CPTResponder>.

Reimplemented in CPTGraph, and CPTPlotAreaFrame.

◆ pointingDeviceUpEvent:atPoint:

- (BOOL) pointingDeviceUpEvent:	(nonnull CPTNativeEvent *)	event
atPoint:	(CGPoint)	interactionPoint

implementation

Informs the receiver that the user has lifted their finger off the screen.

The event is passed in turn to each annotation layer that contains the interaction point. If any layer handles the event, subsequent layers are not notified and this method immediately returns YES.

Parameters

event	The OS event.
interactionPoint	The coordinates of the interaction.

Returns: Whether the event was handled or not.

Reimplemented from <CPTResponder>.

Reimplemented in CPTPieChart, CPTPlot, CPTTradingRangePlot, CPTRangePlot, CPTBarPlot, CPTScatterPlot, CPTGraph, CPTLegend, CPTPlotArea, and CPTPlotAreaFrame.

◆ removeAllAnnotations

- (void) removeAllAnnotations

Removes all annotations from the receiver.

◆ removeAnnotation:

- (void) removeAnnotation: (nullable CPTAnnotation *) annotation

Removes an annotation from the receiver.

Property Documentation

- (nonnull CPTAnnotationArray *) annotations
