The arc graph?

I am a beginner and need help. How do I draw an arc graph? The function must be similar to clock hands, but I do not know how to keep rendered all the steps. Someone help me? How do I edit this?

function drawArc(dc, angle, length, width) 

        {

        var coords = [[-width, -(length)*8/10], [-width, -(length)],[width, -length],[width, -(length)*8/10]];

		var result = new [coords.size()];



		var centerX = dc.getWidth()*3/10;

		var centerY = 130;



		var cos = Math.cos(angle);

		var sin = Math.sin(angle);

		



		for (var i = 0; i < coords.size(); i +=1 )

        {

            var x = (coords[0] * cos) - (coords[1] * sin);

            var y = (coords[0] * sin) + (coords[1] * cos);

            result= [ centerX+x, centerY+y];

        }



        dc.fillPolygon(result);	

	

    }[/CODE]

Thanks for your time. Your function is elegant, but there are little things that do not make sense to me. I'm not a programmer and do not know any. Perhaps someone will help your instructions. I'll hope that programmers from Garmin will create sample for people like me :-)

I know you're not a programmer, but you really keep surprising me with beautifully designed watch faces!
