ORKValueRange Class Reference

Inherits from NSObject
Conforms to ORKValueCollectionType
Declared in ORKChartTypes.h

The ORKValueRange class represents a range between two values of the double type. It can be used in graph chart plots to draw value ranges.

– initWithMinimumValue:maximumValue:

Returns a value range initialized using the specified minimumValue and maximumValue.

- (instancetype)initWithMinimumValue:(double)minimumValue maximumValue:(double)maximumValue

Parameters

minimumValue

The minimumValue to set.
maximumValue

The maximumValue to set.

Return Value

A value range object.

Declared In

ORKChartTypes.h

– initWithValue:

Returns a value range initialized using the specified value for both minimumValue and maximumValue. This is useful for plotting data points that model a single value with no range.

- (instancetype)initWithValue:(double)value

Parameters

value

The minimumValue and maximumValue to set.

Return Value

A value range object.

Discussion

This method is a convenience initializer.

Declared In

ORKChartTypes.h

– init

Returns a value range initialized using the ORKDoubleInvalidValue value for both minimumValue and maximumValue. This denotes an unset or invalid value range. It is useful, for example, for representing unavailable data in discontinous graph chart plots.

- (instancetype)init

Return Value

A value range object initialized with the ORKDoubleInvalidValue value.

Discussion

This method is a convenience initializer.
