The issue you're probably running into is that 1) when exporting a snapshot
from a group, Rev will capture the transparency that is created by multiple
objects being surrounded by empty space and 2) JPEG does not inherently
support transparency.  I would guess that placing some kind of background in
the group behind your graph (a graphic or image) would be enough to solve
the problem.  Alternatively, you could try the following, which should
capture the portion of the card that is behind the group:

 export snapshot from rect (rect of grp theDefaultGrpName) of this cd \
   to file theFileName as JPEG

Hope this helps.
