I presume you have XSTYLE=1 and YSTYLE=1 set, as you should
on ALL contour plots. I think the problem is that you are
looking at the "hole" in the contour plot and *thinking*
that is the problem.

This could probably be fixed if your levels started
with your minimum value. I would set the levels like this:

step = (Max(array) - Min(array)) / 10
levels = Indgen(10) * step + Min(array)

If that doesn't solve the problem, then I'd like to
see that array, cause I don't really believe the story. :-)

Cheers,

David
