Description:
The first plot point is not being passed to the graphs that are based on delta based variables. This is more obvious when viewing a very small interval in the graphs page.

How to repeat:
o Click the graphs tab
o Choose an interval of 10 minutes
o Note that counter based variables (CPU usage etc.) miss the first slot
o Note that absolute based variables (Connections etc.) do not 

Suggested fix:
Tick back one further time slice on delta based values
