This simplified example illustrates the output of Enterprise Vault Reporting's Archived Item Access Trends report.

Say there are four items in the archive, and two users who are accessing the items. User A access two distinct items and User B accesses the other two distinct items.

In the first graph green line shows a count of four, because User A accessed the archive twice and so did User B. The blue line shows a count of two, since only two unique users were involved.

In the second graph, the green line shows a count of four (the total number of accesses is four, as in the first graph). But here the blue line also shows a count of four, because four unique items were accessed. Hence the blue line and the green line overlap.

Figure: Example Archive Access Trends report shows a report that gives the output for this example.
