How to change the center of a circle in netlogo?

This time I'm struggling with changing the center of a circle in netlogo. I have tried using layout-circle and create-ordered-turtle but I can't make the circle choose an other coordinate except the middle one.

to setup-food
  set-default-shape turtles "dot"

repeat num-food
  [patch-at random-pxcor random-pycor [cro 10 [fd radius set color blue]]]

 ;that was my first attempt
 ;now for the second one  

layout-circle turtles radius 
repeat num-food 
[ setxy random-pxcor random-pycor
  foreach range 25 [y -> ask turtle y
[ foreach range (24 - y) [x -> create-link-with turtle (x + (1 + y))]]]
 ]
end

With create-ordered-turtles, you can do:

to setup-food
  set-default-shape turtles "dot"
  repeat num-food [
    let center one-of patches
    cro 10 [
      move-to center
      fd radius
      set color blue
    ]
  ]
end

That is, you need to make sure you're moving all of the turtles to the same place. In your code, they were all going to different random patches before moving.
