Classpublic class Stroke
InheritanceStroke Inheritance Object
ImplementsIStroke

The Stroke class defines the properties for a line. You can define a Stroke object in MXML, but you must attach that Stroke to another object for it to appear in your application. The following example defines two Stroke objects and then uses them in the horizontalAxisRenderer of a LineChart control: 
  ...
  <mx:Stroke id="ticks" color="0xFF0000" weight="1"/>
  <mx:Stroke id="mticks" color="0x0000FF" weight="1"/>
  
  <mx:LineChart id="mychart" dataProvider="{ndxa}">
   <mx:horizontalAxisRenderer>
    <mx:AxisRenderer placement="bottom" canDropLabels="true">
     <mx:tickStroke>{ticks}</mx:tickStroke>
     <mx:minorTickStroke>{mticks}</mx:minorTickStroke>
    </mx:AxisRenderer>
   </mx:horizontalAxisRenderer>
  </LineChart>
  ...

MXML Syntaxexpanded Hide MXML Syntax

The <mx:Stroke> tag inherits all the tag attributes of its superclass, and adds the following tag attributes:

  <mx:Stroke
    Properties
    alpha="1.0"
    caps="null|none|round|square"
    color="0x000000"
    joints="null|bevel|miter|round"
    miterLimit="0"
    pixelHinting="false|true"
    scaleMode="normal|none|noScale|vertical"
    weight="1 (in most cases)"
  />

Property detail
alphaproperty
public var alpha:Number

The transparency of a line. Possible values are 0.0 (invisible) through 1.0 (opaque).

The default value is 1.0..

capsproperty 
public var caps:String = "null"

Specifies the type of caps at the end of lines. Valid values are: "round", "square", and "none".

colorproperty 
public var color:uint = 0

The line color.

The default value is 0x000000 (black)..

jointsproperty 
public var joints:String = "null"

Specifies the type of joint appearance used at angles. Valid values are "round", "miter", and "bevel".

miterLimitproperty 
public var miterLimit:Number = 0

Indicates the limit at which a miter is cut off. Valid values range from 0 to 255.

The default value is 0.

pixelHintingproperty 
public var pixelHinting:Boolean = false

Specifies whether to hint strokes to full pixels. This value affects both the position of anchors of a curve and the line stroke size itself.

The default value is false.

scaleModeproperty 
public var scaleMode:String = "normal"

Specifies how to scale a stroke. Valid values are "normal", "none", "vertical", and "noScale".

The default value is "normal".

weightproperty 
weight:Number  [read-write]

The line weight, in pixels. For many charts, the default value is 1 pixel.
