Chipmunk Physics

I'm using chipmunk 5.3.5 with cocos2d. I was expecting to have to make sprites to represent constraints that I want to display but I'm getting a green line representing each constraint with a green square at the anchor points whether I want them or not. For this example I'm using a slideJoint. That's shows what's going on very nicely but I'd like to display the constraints in a different way. How can I turn off the green line and the green anchor points? I'm new to chipmunk.

Chipmunk does no rendering. You must have a debug rendering node for Chipmunk in your scene somewhere. I didn't really have an official Cocos2D one for that old of a version of Chipmunk, so I'm not sure what to tell you to look for.
