meta file size

[Boyin Huang]

When I plotted a T-S diagram, the meta file is very large(50MB). When this
large meta file was transferred into a ps or gif file and viewed by
ghostview, I found part of the file was missing (Say, it should contain
1000 scattered dots as shown in the grads display window but only 900 was
showen up), and the ps file size reached 120MB.

What caused the problem?
Is this because the grads set a file size limit?
Is there any way to fix the problem?

Thanks
