[ncl-talk] issue with gsn_csm_xy

[Dave Allured - NOAA Affiliate]

I think NCL arg numbering is zero based, so arg (3) is hres.  Now there
might be something going on with hres, elsewhere in your code.
printVarSummary (hres)

Also note that you are setting hres to True, but not attaching any
attributes.  Perhaps try False.

If that doesn't get it, then look at printVarSummary for all four args.
Compare with the documented function prototype.
