Overview

This is a base class for all numeric axes. This class should not be allocated.

Tasks

Properties

actualIsLogarithmic

A Boolean value that determines whether the axis is logarithmic. (read-only)

@property (nonatomic, readonly) BOOL actualIsLogarithmic

Discussion

This property returns YES if the axis uses a logarithmic scale. This property will return NO if the axis was set to use a linear scale, or when a logarithmic scale could not be set.

Declared In

Axis.h

actualMaximumValue

Returns the maximum visible value on the axis. (read-only)

@property (nonatomic, readonly) float actualMaximumValue

Discussion

This property will return the final maximum visible value after the chart has made various range adjustments. Adjustments can be made as a result of rounding or auto-calculating the axis range.

Declared In

Axis.h

actualMinimumValue

Returns the minimum visible value on the axis. (read-only)

@property (nonatomic, readonly) float actualMinimumValue

Discussion

This property will return the final minimum visible value after the chart has made various range adjustments. Adjustments can be made as a result of rounding or auto-calculating the axis range.

Declared In

Axis.h

interval

A value that determines the axis interval.

@property (nonatomic) float interval

Discussion

The axis interval determines the values and the frequency of axis labels.

Declared In

Axis.h

isLogarithmic

A Boolean value that determines whether the axis uses a logarithmic scale.

@property (nonatomic) BOOL isLogarithmic

Declared In

Axis.h

logarithmBase

A value that determines the logarithm base.

@property (nonatomic) int logarithmBase

Discussion

This property is used to specify the logarithm base to use when the axis uses a logarithmic scale.

Declared In

Axis.h

maximum

A value that determines the axis maximum.

@property (nonatomic) float maximum

Declared In

Axis.h

minimum

A value that determines the axis minimum.

@property (nonatomic) float minimum

Declared In

Axis.h

referenceValue

A value that determines the starting rendering point for series polygons.

@property (nonatomic) float referenceValue

Discussion

This property is only used by certain column and area series. The value of this property is used by the series as the base starting point for drawing shapes. For example, a column of a column series typically starts drawing at Y=0 and finishes at some value. This property will make the column start drawing at reference value insted of 0.
