I thought it had something to do with that. I tried what you said but I still get that gap sometimes. I'd say every second graph update (I'm using -z as well so not all the graphs update every 2 minutes). I tried setting the endtime to now-240 (and greater) and still the same thing. Sometimes there's no gap, sometimes there is.
