Animate

I want to draw then animate a line using Tweener. The problem with my code is it does not just tween the width it tweens the dot I create in the x and y directions. giving me big blobs rather than long thin lines.

Any help would be appreciated.

    public function smallBoxes()
    {
        
        
       
        
        var lineDrawing:MovieClip = new MovieClip();
        addChild(lineDrawing);
        lineDrawing.graphics.lineStyle(1, 0xFFFFFF);
        lineDrawing.graphics.moveTo(0,0); 
        lineDrawing.graphics.lineTo(1, 0);
        
        Tweener.addTween(lineDrawing, {width:955, time:1, delay:1, transition:"elastic"});
    
        

    }
