Properties

alwaysShowZeroLevel Property

Gets or sets the value indicating whether the range should always include a zero value.

Declaration

@property (readwrite) BOOL alwaysShowZeroLevel

Property Value

Type	Description
BOOL	YES if the range should include a zero value; otherwise NO.

autoRangeMode Property

Gets or sets the range automatically calculation mode.

Declaration

@property (readwrite) DXAutoRangeMode autoRangeMode

Property Value

Type	Description
DXAutoRangeMode	The DXAutoRangeMode enumeration value that specifies how to automatically calculate axis’ range.

gridAlignment Property

Gets or sets the major tickmarks and gridlines’ alignment on the numeric values axis.

Declaration

@property (readwrite) CGFloat gridAlignment

Property Value

Type	Description
CGFloat	The grid’s alignment

gridOffset Property

Gets or sets the first major tickmark’s and gridline’s offset from the range’s minimum value on the numeric values axis.

Declaration

@property (readwrite) CGFloat gridOffset

Property Value

Type	Description
CGFloat	The first major tickmark’s and gridline’s coordinate, in axis units.

labelTextFormatter Property

Gets or sets a formatter that provides numeric Y-axis labels’ text.

Declaration

@property (readwrite, nullable) id<DXNumericAxisLabelTextFormatter> labelTextFormatter

Property Value

Type	Description
id<DXNumericAxisLabelTextFormatter>	An object of a class implementing the DXNumericAxisLabelTextFormatter interface that formats axis values.
