Changing Views on Tree Graphs

[Jaiden]

I'm new to the whole cacti/nagios setup, having inherited it from the former IT admin that worked here. Basically, we use cacti to monitor a few clients with alot of nodes, and my boss uses a print out of the tree view on that group (where it shows all of the graphs for each node) to give to the client to show them a summary of the past week of traffic and disk usage and the like. problem is that the tree view only, by default, shows the last 24 or so hours (and for some reason, no one noticed this before me). now i'm trying to figure out how to make it show up the last 7 days or so or maybe set it up so i can create a report of some kind with similiar data. anyone have any ideas on this? i tried editing the time on the graphs but it only applies to preview mode, not graph tree mode.

Thanks,
