Detailed Description

A set of cartesian (X-Y) axes.

Method Documentation

◆ initWithFrame:

- (nonnull instancetype) initWithFrame: (CGRect newFrame
implementation

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

This is the designated initializer. The axes array will contain two new axes with the following properties:

Axiscoordinate tickDirection
xAxisCPTCoordinateXCPTSignNegative
yAxisCPTCoordinateYCPTSignNegative
Parameters
newFrameThe frame rectangle.
Returns
The initialized CPTXYAxisSet object.

Reimplemented from CPTAxisSet.

◆ layoutSublayers

- (void) layoutSublayers
implementation

Updates the layout of all sublayers. Sublayers (the axes) fill the plot area frame’s bounds.

This is where we do our custom replacement for the Mac-only layout manager and autoresizing mask. Subclasses should override this method to provide a different layout of their own sublayers.

Reimplemented from CPTLayer.

Property Documentation

◆ xAxis

- (nullable CPTXYAxis *) xAxis
readnonatomicassign

The x-axis.

◆ yAxis

- (nullable CPTXYAxis *) yAxis
readnonatomicassign

The y-axis.
