Graphs not showing up

[newtonbm]

I have searched the posts and tried eveyrthing int hem but I still can't get graphs to show up. I have now errors in any logs. When I go to "Graphs" and try to view my graphs I see my Cisco Interfaces, but I see no graph. Any ideas where to start? I think it might be the cron job but I tried various syntaxes and it still doesn't work.

Fixed it. Ping wasn't working so I used the method of SNMP int he settings page.
