graticule and fill

[Pal Jeremy <jpal@xxxxxxxxxxxxxxx>]

  Hi everybody...

I am having trouble making graticules with the fill command.  
When I plot my data using the following, the fill colors cover
the graticules everywhere except in the northeastern hemsisphere
and where there is missing data:

  go graticule
  fill rt

Note that everything works perfectly when I use the shade
command. Also, this seems occur on both linux and sun machines.

Any ideas how to get around this?  I could probably define a
second identical viewport and then plot the graticules over the
first viewport, but this does not seem so elegant.

Thanks in advance.
