Are you aware that if ANY of the values is unknown them the result is
unknown ? So for example, if you were not collecting samples for one
system for a while, then you would have a gap in the graph.
You have to do a test for unknown values and replace them with zeros
before adding them all together. Have a look back through the
archives, it's come up before.
