I suspect Raul & Devon are right about the cause of your confusion. If the values you are expecting to plot starting with: d=. 4 _3 6 2 _3 _5 2 _3 are: 4 1 7 9 6 1 3 1
Then you could use: plot k=. |. foo/\. |.d ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
