Try the Wall Chart report found under Reports>Chart>Wall Chart.
Just as Renee remarked for the narrative reports, the ancestor chart does not help. But try the descendant chart staring with your great grandfather.
I tested the wall chart display for one of my gr-gr-gr grandfathers with 3 wives and 13 children.
To make it look more interesting, try to color code your branch of ancestors. Also try to color code the descendants of the other gr-grandmother. Collisions of color coding keep the last one used.
Thanks very much for your tip on colour coding different branches - it has made the report a lot more interesting :-)
