Plot handles timestamps wrong
Plot (inconsistently?) handles timestamps wrong and plots at wrong timestamp:
@usmsk_luebbe and @uyrdb_dormanns looked a bit into replication and cause: Seems like the (expected inconsistent) difference between metrics timestamp and response timestamp causes trouble... Issue can be replicated with (real) static data:
(use as plot.py in master (d5594bb9) and plot something)
-> fix crucial!
