Using data logs, I can't see graphs at the bottom of the page (piecharts and so). Is it normal ? For example, as I must reset logs every 3 hours, I can't see the evolution of traffic, or kind of traffic, during 24 hours ... Because no charts under the page !
I'm not quite sure what you mean. With the reset interval set to 3 hours, you will only see the last 3 hours in the log. But the charts should be visible. Can you send me a screenshot describing the problem?
