ORKGraphChartView Class Reference

Inherits from	UIView
Declared in	ORKGraphChartView.h ORKGraphChartView.m

Overview

The ORKGraphChartView class is an abstract class which holds properties and methods common to concrete subclasseses.

You should not instantiate this class directly; use one of the subclasses instead. The concrete subclasses are ORKLineGraphChartView, ORKDiscreteGraphChartView, and ORKBarGraphChartView.

`minimumValue`

The minimum value of the y-axis.

@property (nonatomic, readonly) double minimumValue

Discussion

You can provide this value to an instance of ORKGraphChartView by implementing the optional minimumValueForGraphChartView: method of the ORKGraphChartViewDataSource protocol.

If minimumValueForGraphChartView: is not implemented, the minimum value is assigned to the smallest value of the minimumValue property of all ORKValueRange instances returned by the graph chart view data source.

Declared In

ORKGraphChartView.h

`maximumValue`

The maximum value of the y-axis.

@property (nonatomic, readonly) double maximumValue

Discussion

You can provide this value instance of ORKGraphChartView by implementing the optional maximumValueForGraphChartView: method of the ORKGraphChartViewDataSource protocol.

If maximumValueForGraphChartView: is not implemented, the maximum value is assigned to the largest value of the maximumValue property of all ORKValueRange instances returned by the graph chart view data source.
