Detailed Description

A layer drawn on top of the graph layer and behind all plot elements.

All graph elements, except for titles, legends, and other annotations attached directly to the graph itself are clipped to the plot area frame.

Method Documentation

◆ initWithFrame:

- (nonnull instancetype) initWithFrame: (CGRect newFrame
implementation

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

This is the designated initializer. The initialized layer will have the following properties:

Parameters
newFrameThe frame rectangle.
Returns
The initialized CPTPlotAreaFrame object.

Reimplemented from CPTBorderedLayer.

◆ pointingDeviceCancelledEvent:

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

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

Parameters
eventThe OS event.
Returns
Whether the event was handled or not.

Reimplemented from CPTAnnotationHostLayer.

◆ pointingDeviceDownEvent:atPoint:

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

Informs the receiver that the user has touched the screen.

Parameters
eventThe OS event.
interactionPointThe coordinates of the interaction.
Returns
Whether the event was handled or not.

Reimplemented from CPTAnnotationHostLayer.

◆ 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.

Parameters
eventThe OS event.
interactionPointThe coordinates of the interaction.
Returns
Whether the event was handled or not.

Reimplemented from CPTAnnotationHostLayer.

◆ pointingDeviceUpEvent:atPoint:

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

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

Parameters
eventThe OS event.
interactionPointThe coordinates of the interaction.
Returns
Whether the event was handled or not.

Reimplemented from CPTAnnotationHostLayer.
