[Graphing of] Calculated metric is delayed from the underlying metric

[lennys26]

Hello.

I have 2 base metrics and created a calculated item which adds them together. What I am noticing is that when I graph these items together, the calculated item appears to be delayed.



The calculation that I am using is:
last("hostA,parameterA")+last("hostA,parameterB")

Are there any thoughts as to why a delay is being introduced? And, more importantly, any ideas how to resolve this?

Thanks.



* I am using version 4.4.10.
