| Runtime Versions: | Flash Player 9, AIR 1.1 |
Draws an arc in the target Graphics object.
Parameters
| g:Graphics — The Graphics object to draw into.
|
| |
| x:Number — The horizontal origin of the arc.
|
| |
| y:Number — The vertical origin of the arc.
|
| |
| startAngle:Number — The starting angle, in radians, of the arc.
|
| |
| arc:Number — The sweep, in radians, of the arc.
|
| |
| radius:Number — The horizontal radius, in pixels, of the arc
|
| |
| yRadius:Number (default = NaN) |

public static function drawPolyLine(g:Graphics, pts:Array, start:int, end:int, hProp:String, vProp:String, stroke:IStroke, form:Object, moveToStart:Boolean = true):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Draws a line connecting the datapoints using one of various forms.
Parameters
| g:Graphics — The Graphics object to draw into.
|
| |
| pts:Array — An Array of datapoints that define the line.
|
| |
| start:int — The index of the first point in the pts Array to use when drawing the line.
|
| |
| end:int — The index of the last point, exclusive, to use when drawing the line.
|
| |
| hProp:String — The name of the property in the objects contained in the pts Array that defines the horizontal position of the points in the line.
|
| |
| vProp:String — The name of the property in the objects contained in the pts Array that defines the vertical position of the points in the line.
|
| |
| stroke:IStroke — The Stroke used to render the line.
|
| |
| form:Object — The form to render the line with. Valid values are "segment","horizontal","vertical","step","reverseStep", or "curve". These forms are similar to the LineSeries class's form property.
|
| |
| moveToStart:Boolean (default = true)false to use this function to continue a line in progress.
|
public static function fillFromStyle(v:Object):IFill| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Converts a style value into a Fill object. This convenience method converts a value assigned through styles into a Fill object
that can be used to fill an area on the screen. If the value is numeric, this function converts it into a corresponding SolidColor.
Parameters
| v:Object — The value to convert into a Fill.
|
Returns | IFill — The corresponding IFill object.
|

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Applies the values in a Stroke to the provded Graphics object. This utility function
applies the Stroke passed in, or clears the line style of the provided Graphics object
if the ls parameter is set to null.
Parameters
| g:Graphics — The Graphics object to modify.
|
| |
| ls:IStroke — The IStroke instance to apply; set to null to render with no Stroke.
