[ncl-talk] Contour Plot Help

[Rick Brownrigg]

Hi,

There would be a practical limit based upon your machine. Did you try
intermediate values between 100M and 10G?  How about Adam's suggestion of
explicitly setting contour levels -- trying something fairly coarse and
then dialing it back in until things fail.  There's obviously something
about the data that's requiring extreme amounts of workspace memory -- but
its hard to say what without some sleuthing...
