Are you looking for a chart that shows a genealogy tree with every
person in your database, a listing of every person in your database
and their relationship to one person or something else.

The former is not available I think, but I am not sure. The only
program I have seen do this is family tree maker but this is Windows
only and reviews are not positive.

There used to be a report that gave a listing of every person in your
database and their relationship to one person but I cannot see it at
the moment.

To be honest, this is not the best place to ask this. GRAMPS has a
very active mailing list and many members are on the irc channel. If
you need more detail please ask. I know the website was down the other
day due to server issues, but it is back up now.
