When using charts in your applications, you typically will not need to interact with the CartesianTransform object. Transforms are created automatically by the built-in chart types and used by the series contained within so that they can transform data into rendering coordinates.

pixelHeight | egenskap |
pixelHeight:Number [lässkyddad] | Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
The height of the data area that the CartesianTransform represents, in pixels. The containing chart sets this property explicitly during layout. The CartesianTransform uses this property to map data values to screen coordinates.
Implementering
public function set pixelHeight(value:Number):voidpixelWidth | egenskap |
pixelWidth:Number [lässkyddad] | Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
The width of the data area that the CartesianTransform represents, in pixels. The containing chart sets this property explicitly during layout. The CartesianTransform uses this property to map data values to screen coordinates.
Implementering
public function set pixelWidth(value:Number):voidCartesianTransform | () | Konstruktor |
public function CartesianTransform()| Språkversion: | ActionScript 3.0 |

Constructor.
invertTransform | () | metod |
override public function invertTransform(... values):Array| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Transforms x and y coordinates relative to the DataTransform coordinate system into a 2-dimensional value in data space.
Parametrar
... values — The x and y positions (in that order).
|
Array — An Array containing the transformed values.
|
transformCache | () | metod |
override public function transformCache(cache:Array, xField:String, xConvertedField:String, yField:String, yConvertedField:String):void| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.
Parametrar
cache:Array — An array of objects containing the data values
in their fields.
This is also where this function stores the converted numeric values.
| |
xField:String — The field where the data values for the x axis are stored.
| |
xConvertedField:String — The field where the mapped x screen coordinate
is stored.
| |
yField:String — The field where the data values for the y axis are stored.
| |
yConvertedField:String — The field where the mapped y screen coordinate
is stored.
|

VERTICAL_AXIS | Konstant |
public static const VERTICAL_AXIS:String = "v"| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
