Declaration

@property (readonly, nonnull) NSArray<DXConstantLineBase*> *constantLines

Property Value

Type Description
NSArray<DXConstantLineBase *> *

The array of DXConstantLineBase objects that the axis contains.

Cast the line's object to one of the descendant classes (DXQualitativeConstantLine, DXNumericConstantLine or DXDateTimeConstantLine) to obtain a constant line's value. Note that, the descendant class should be compatible with the axis type, whose constant lines are processed.

DXAxisBase.hidden Property

Gets or sets the value indicating whether an axis is hidden.

Declaration

@property (readwrite) BOOL hidden

Property Value

Type Description
BOOL

YES if the axis should be hidden; otherwise NO.

DXAxisBase.hintOptions Property

Gets or sets axis hint options that configure how the Crosshair Cursor interacts with the axis.

Declaration

@property (readwrite, nullable) DXAxisHintOptions *hintOptions

Property Value

Type Description
DXAxisHintOptions *

The hint options storage.

DXAxisBase.label Property

Gets or sets axis labels' settings.

Declaration

@property (readwrite, nullable) DXAxisLabel *label

DXAxisBase.position Property

Gets or sets the position of an axis.

Declaration

@property (readwrite) DXAxisPosition position

Property Value

Type Description
DXAxisPosition

DXAxisBase.strips Property

Returns the array of strips that the axis contains.

Declaration

@property (readonly, nonnull) NSArray<DXStripBase*> *strips

Property Value

Type Description
NSArray<DXStripBase *> *

The array of DXStripBase objects that the axis contains.

Cast the strip object to one of the descendant classes (DXQualitativeStrip, DXNumericStrip or DXDateTimeStrip) to obtain a strip's obtain minimum and maximum values. Note that, the descendant class should be compatible with the axis type, whose strips are processed.

DXAxisBase.style Property
