Can I change properties of an existing line?

programming flash
1

So I draw a line using the graphics object on a Shape or Sprite, using something like:


		mySprite.graphics.lineStyle(1, 0x333333, 1, false, LineScaleMode.VERTICAL, CapsStyle.NONE, JointStyle.MITER, 10);
		mySprite.graphics.beginFill(0x000044);
		mySprite.graphics.moveTo(xval+5, y_st);
		mySprite.graphics.lineTo(xval+5, yval);
		mySprite.graphics.endFill();

How can I change the thickness of the line once it’s drawn? I don’t think it’s possible. I’ve also tried changing the ScaleY of the line, but even changeing the LineScaleMode from VERTICAL hasn’t helped me here.

Does anyone have any ideas?

many thanks in advance,
Henry
