Plotting across International Dateline

Hello NCL-users,

I am encountering a problem identical to the one referenced in this
thread from 2006:
http://www.ncl.ucar.edu/Support/talk_archives/2006/0968.html

trying to plot across the International Dateline and hoped it was now
a solved problem. I've tried various approaches to reordering the
data, among them: mpMin/MaxLonF resources, using lonFlip, lonPivot,
and using the result for the 2006 thread. I'm trying to plot 100E to
10W, more than half the globe, which seems to be part of the problem,
e.g. though the t variable has a longitude of 0..360, trying to plot
0..180+ degrees or 0..72+ indices causes the whole globe to plot. I'm
not attaching code because my experimentations have been in
interactive mode for the most part, but the summaries of the
temperature and lon variables are below. I'd be grateful to know if
there is an effective approach to this seemingly simple problem. I
feel silly because I know I've done this before using CCSM output! I'd
be happy to send a sample of my data (GFDL CM2 output) to interested
parties.

Thanks everyone!
