Detailed Description

A group of grid line layers.

When using separate axis layers, this layer serves as the common superlayer for the grid line layers. Otherwise, this layer handles the drawing for the grid lines. It supports mixing the two modes; some axes can use separate grid line layers while others are handled by the grid line group.

Method Documentation

◆ initWithFrame:

- (nonnull instancetype) initWithFrame: (CGRect newFrame
implementation

Initializes a newly allocated CPTGridLineGroup 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 CPTGridLineGroup object.

Reimplemented from CPTLayer.

Property Documentation

◆ major

- (BOOL) major
readwritenonatomicassign

If YES, draw the major grid lines, else draw the minor grid lines.

◆ plotArea

- (nullable CPTPlotArea *) plotArea
readwritenonatomicweak

The plot area that this grid line group belongs to.
