You typically do not need to interact with the PolarTransform object. Transforms are created automatically by the built-in chart types and are used by the series contained within to transform data into rendering coordinates.

Constructor.
方法詳細資訊
setSize | () | 方法 |
public function setSize(width:Number, height:Number):void| 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 |
Sets the width and height that the PolarTransform uses when calculating origin and radius. The containing chart calls this method. You should not generally call this method directly.
參數
width:Number — The width, in pixels, of the PolarTransform.
| |
height:Number — The height, in pixels, of the PolarTransform.
|
transformCache | () | 方法 |
override public function transformCache(cache:Array, aField:String, aConvertedField:String, rField:String, rConvertedField:String):void| 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 |
Maps a set of numeric values representing data to screen coordinates.
This method assumes the values are all numbers,
so any non-numeric values must have been previously converted
with the mapCache() method.
參數
cache:Array — An array of objects containing the data values
in their fields. This is also where this function
will store the converted numeric values.
| |
aField:String — The field where the data values for the x axis
can be found.
| |
aConvertedField:String — The field where the mapped x screen coordinate
will be stored.
| |
rField:String — The field where the data values for the y axis
can be found.
| |
rConvertedField:String — The field where the mapped y screen coordinate
will be stored.
