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>
  ...

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="1"
    pixelHinting="false|true"
    scaleMode="normal|none|horizontal|vertical"
    weight="1 (in most cases)"
  />

Constructor

public function Stroke(color:uint = 0x000000, weight:Number = 0, alpha:Number = 1.0, pixelHinting:Boolean = false, scaleMode:String = "normal", caps:String = null, joints:String = null, miterLimit:Number = 1)

Constructor.

Parameters

	`color:uint` (default = `0x000000`) — Specifies the line color. The default value is 0x000000 (black).

	`weight:Number` (default = `0`) — Specifies the line weight, in pixels. The default value is 0.

	`alpha:Number` (default = `1.0`) — Specifies the alpha value in the range 0.0 to 1.0. The default value is 1.0 (opaque).

	`pixelHinting:Boolean` (default = `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.

	`scaleMode:String` (default = "`normal`") — A value from the LineScaleMode class that specifies which scale mode to use. Valid values are `LineScaleMode.HORIZONTAL`, `LineScaleMode.NONE`, `LineScaleMode.NORMAL`, and `LineScaleMode.VERTICAL`. This parameter is optional, with a default value of `LineScaleMode.NORMAL`.

	`caps:String` (default = `null`) — Specifies the type of caps at the end of lines. Valid values are `"round"`, `"square"`, and `"none"`. The default value is `null`.

	`joints:String` (default = `null`) — Specifies the type of joint appearance used at angles. Valid values are `"round"`, `"miter"`, and `"bevel"`. The default value is `null`.

	`miterLimit:Number` (default = `1`) — Indicates the limit at which a miter is cut off. Valid values range from 1 to 255. The default value is 1.
