Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

IChartElement2 defines the base set of properties and methods required by a UIComponent to be representable in the data space of a chart. Any component assigned to the series, backgroundElements, or annotationElements Arrays of a chart must implement this interface.

Method Detail
dataToLocal()method
public function dataToLocal(... dataValues):Point

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Converts a tuple of data values to an x-y coordinate on screen. Call this function to transform data on to the screen using the same transform that the individual elements go through. For example, to create a custom highlight for a data region of a chart, you might use this function to determine the on-screen coordinates of the range of interest.

For Cartesian chartelements, you typically pass two values. The first value maps to the horizontal axis, and the second value maps to the vertical axis.

For polar charts, the first value maps to the angular axis, and the second maps to the radial axis.

Parameters

... dataValues — The data values to convert to coordinates.

Returns
Point — Coordinates that are relative to the chart.
getAllDataPoints()method 
public function getAllDataPoints():Array

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Returns an array of HitData of the items of all the underlying objects that implement IChartElement2 whose dataTips are to be shown when showAllDataTips is set to true on chart.

Returns
Array — The HitData objects describing the data points
localToData()method 
public function localToData(pt:Point):Array

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Converts a coordinate on screen to a tuple of data values. Call this function to determine what data values a particular point on-screen represents.

Individual chart types determine how this transformation occurs. The point should be relative to the chart's coordinate space.

Parameters

pt:Point — The Point to convert.

Returns
Array — The tuple of data values.
