As Adam says, this is very dependant on devices updating their counters quickly enough. On some of our older/larger gear (read: 6509's full of 48-port line cards), we're seeing the counters only being updated every 15 seconds or so, which makes realtime graphing very difficult. We usually end up setting the interval to 15 or 30 seconds (We're still running a pre-fork observium codebase which has been heavily modified) to get a smooth graph.

I'm assuming you're talking about the real time graph.

This graph relies on devices updating counters quickly enough to draw a smooth graph without spikes.

Also, you need to provide links to screenshots for problems.
