dataToLocal | () | 方法 |
public function dataToLocal(... dataValues):Point| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | 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.
參數
... dataValues — The data values to convert to coordinates.
|
Point — Coordinates that are relative to the chart.
|
getAllDataPoints | () | 方法 |
public function getAllDataPoints():Array| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | 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.
Array — The HitData objects describing the data points
|
localToData | () | 方法 |
public function localToData(pt:Point):Array| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | 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.
參數
pt:Point — The Point to convert.
|
Array — The tuple of data values.
