Use annotation. Set the color according to the angle. Should be easy, right?
You should not have removed all the comments when you posted your code. I'm sure you had them in there, like all good programmers do, but when you removed them it made it difficult for us to follow your code. Please put the comments back in and specifically call out what variables are the (x,y) centers of the small spots, and what variable contains the angles that you'd like the arrows pointing along.
