Graph mismatch with data from backend

[jodok]

it seems that under some circumstance that graph doesn't match with the data from the backend. e.g. i'm visualizing the load['1'] of our demo cluster - and it shows that the node demo-08 has a load of 2.0 - but it hasn't. i also couldn't find that in the response of the backend.

{
    "cols": [
        "time",
        "avg(load['1'])",
        "hostname"
    ],
    "duration": 14,
    "rows": [
