It was not my code - except for the suggestion for the last line.
But as to your problem, the code is as I have it (and it plots
properly on my computer). The only thing I can think of is that the
variable "wc" conflicts with a plug-in somewhere on your system.
Try changing "wc" to something else (in all places where it exists -
you'll find it in the cutoff line.
