These reporters give the minimum x-coordinate and minimum y-coordinate, (respectively) for patches, which determines the size of the world.
Unlike in older versions of NetLogo the origin does not have to be at the center of the world. However, the minimum x- and y- coordinates must be less than or equal to zero.
Note: You can set the size of the world only by editing the view -- these are reporters which cannot be set.
