before anything else:

> * rrdtool fetch myrrd.rrd AVERAGE -s '20160608 18:00' -e '20160608 18:00'*

> --start '20160608 18:00'
> --end '20160608 1800'

What does the graph show as end time? Is it really 24 hours after start
time? Not sure if "1800" will be recognized as "18:00".

If it is: make sure the amount of pixels in the graph is an integer number
times the amount of CDPs you're graphing.

E.g. if you are collecting data in a one hour resolution, the number of
pixels in the graph should be n*24 (360 would be a nice number in that
