oplot - error in plotting to Z buffer only [message #14249]

Well, I'm stumped.

I have a routine to automatically generate a bunch o'gifs.
Usually it works fine.

On one set of data it fails with the error:

% OPLOT: No valid points, must have at least 2 distinct points

But, but - I *do* have points to plot!
If I run this interactively I can re-enter the command after it gives
the error, and it works fine. (But .con does not)

AND if I plot to an X-window instead of to the Z-buffer (as I usually
do when generating gifs) it runs fine.

Has anyone seen a similar discrepancy?
Is there something I need to know about the Z buffer?

Thanks.
