[Observium] Load Graph, 'm'illions?

Sorry if this has been asked before, couldn't find the answer in a quick search. Graphing Linux load average on a busy machine I see integer numbers, which is expected "20" for example, but graphing an almost idle machine (load 0.22), it's graphed as 220 m. Is there something I need to adjust?, is a RRD limitation?

Regards,
