Are you sure, that small_grib is working correctly?
When I use -undefine out_box -60:100 43:90, everything goes fine.
Now, with -small_grib -60:100 43:90 I get lots of
"Data Request Warning:  Request beyond file limits"
and no charts.

This are my map definitions. I have to say that I came to the values by
testing rather than thinking about them... But to me it looks like all
values are within the boundaries...

if (map = 'nordic')
  'set mproj nps'
  'set mpvals -10 51 48 80'
  'set lon -60 100'
  'set lat 43 90'
  'set mpdset newmap'
endif

if (map = 'finland')
  'set mproj nps'
  'set mpvals 10 40.63 59 71'
  'set lon 0 60'
  'set lat 55 80'
  'set mpdset hires'
endif

if (map = 'germany')
  'set mproj nps'
  'set mpvals 0 20 46.15 57'
  'set lon -15 60'
  'set lat 45 70'
  'set mpdset hires'
endif

Terve,
Stefan
