Re: _FillValue on XY plots

All,

This bug was fixed and will be in the next release of NCL. As always,
if you need a fix now, drop me an email.

The bug was if you were using markers in an XY plot and your X or Y
data contained missing values, *and* you were setting one of the
trX/YMin/MaxF resources to be a value outisde the value of the missing
value, then the missing values were still being plotted.
