axis:minorTickLabelWasSelected:

- (void) axis:		(nonnull CPTAxis *)	axis
minorTickLabelWasSelected:		(nonnull CPTAxisLabel *)	label

(Optional) Informs the delegate that a minor tick axis label received both the touch down and up events.

Parameters

axis:minorTickTouchDown:

- (void) axis:		(nonnull CPTAxis *)	axis
minorTickTouchDown:		(nonnull CPTAxisLabel *)	label

(Optional) Informs the delegate that a minor tick axis label touch started.

Parameters

- (void) axis:		(nonnull CPTAxis *)	axis
minorTickTouchDown:		(nonnull CPTAxisLabel *)	label
withEvent:		(nonnull CPTNativeEvent *)	event

(Optional) Informs the delegate that a minor tick axis label touch started.

Parameters

axis	The axis.
label	The selected minor tick axis label.
event	The event that triggered the selection.

axis:minorTickTouchUp:

- (void) axis:		(nonnull CPTAxis *)	axis
minorTickTouchUp:		(nonnull CPTAxisLabel *)	label

(Optional) Informs the delegate that a minor tick axis label touch ended.

Parameters

axis:shouldUpdateAxisLabelsAtLocations:

- (BOOL) axis:		(nonnull CPTAxis *)	axis
shouldUpdateAxisLabelsAtLocations:		(nonnull CPTNumberSet *)	locations

(Optional) This method gives the delegate a chance to create custom labels for each tick. It can be used with any labeling policy. Returning NO will cause the axis not to update the labels. It is then the delegate’s responsibility to do this.

Parameters

axis	The axis.
locations	The locations of the major ticks.

Returns

YES if the axis class should proceed with automatic labeling.

axis:shouldUpdateMinorAxisLabelsAtLocations:

- (BOOL) axis:		(nonnull CPTAxis *)	axis
shouldUpdateMinorAxisLabelsAtLocations:		(nonnull CPTNumberSet *)	locations

(Optional) This method gives the delegate a chance to create custom labels for each minor tick. It can be used with any labeling policy. Returning NO will cause the axis not to update the labels. It is then the delegate’s responsibility to do this.

Parameters

axis	The axis.
locations	The locations of the minor ticks.

Returns

YES if the axis class should proceed with automatic labeling.

axisDidRelabel:

- (void) axisDidRelabel:

(nonnull CPTAxis *)

axis

(Optional) The method is called after the axis is relabeled to allow the delegate to perform any necessary cleanup or further labeling actions.

Parameters

axis

The axis.

axisShouldRelabel:

- (BOOL) axisShouldRelabel:

(nonnull CPTAxis *)

axis

(Optional) Determines if the axis should relabel itself now.

Parameters

axis

The axis.

Returns

YES if the axis should relabel now.
