pm3d question

[Ethan A M. <merritt@u.washington.edu>]

Can anyone explain to me why the two surfaces produced
by the command below are colored so differently?

  splot x with pm3d, y with pm3d

The "y" surface is colored smoothly, but the "x"
surface is colored in 9 increments only.
What command would I use to get two smoothly
colored surfaces?
