I Noticed that, thanks for explaining.

Ah that's what the 'real' issue was!
I didn't realize that 'rrdtool graph' started to consolidate data based
on the width.
So if I understand correctly, it uses 1px for 1 sample? if there are
more samples then pixels it will consolidate the data?
Is there a way to let RRD tool figure the width out automatically?
without consolidating the data? Reading the docs it seems
--full-size-mode could help me here?
I couldn't test that as the version I run (1.2.19) does not recognize
Thanks again for your time.
