Very interesting. Not very easy to guess though :-), thanks. Can we
have any interval?
I wonder what's the utility of having several RRA lines. My creation
If we can get any interval from the resolution, as the manual says
it'll try to, only one RRA for average would be necessary. I've tried
several values, substituted in END=..., but only those corresponding
to an interval of one of the RRA lines worked.
Now, the manual says rrdgraph will adjust the resolution to the size
of the gif. But if one cannot specify any resolution, it means one
cannot have an arbitrary size for the gif, right?
