The DataDescription structure is used by ChartElements to describe the characteristics of the data they represent to Axis objects that auto-generate values from the data represented in the chart. ChartElements displaying data should construct and return DataDescriptions from their describeData() method when invoked.

Property Detail

boundedValues

property

public var boundedValues:Array

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

An Array of BoundedValue objects describing the data in the element. BoundedValues are data points that have extra space reserved around the datapoint in the chart's data area. If requested, a chart element fills this property with whatever BoundedValues are necessary to ensure enough space is visible in the chart data area. For example, a ColumnSeries that needs 20 pixels above each column to display a data label.

max

property

public var max:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The maximum data value displayed by the element.

min

property

public var min:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The minimum data value displayed by the element.

minInterval

property

public var minInterval:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The minimum interval, in data units, between any two values displayed by the element.

padding

property

public var padding:Number

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The amount of padding, in data units, that the element requires beyond its min/max values to display its full values correctly .

REQUIRED_BOUNDED_VALUES

Constant

public static const REQUIRED_BOUNDED_VALUES:uint = 0x2

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

A bitflag passed by the axis to an element's describeData() method. If this flag is set, the element sets the boundedValues property.

REQUIRED_MIN_INTERVAL

Constant

public static const REQUIRED_MIN_INTERVAL:uint = 0x1

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

A bitflag passed by the axis to an element's describeData() method. If this flag is set, the element sets the minInterval property.

REQUIRED_MIN_MAX

Constant

public static const REQUIRED_MIN_MAX:uint = 0x4

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

A bitflag passed by the axis to an element's describeData() method. If this flag is set, the element sets the DescribeData.min and DescribeData.max properties.

REQUIRED_PADDING

Constant

public static const REQUIRED_PADDING:uint = 0x8

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

A bitflag passed by the axis to an element's describeData() method. If this flag is set, the element sets the DescribeData.padding property.
