timechart span starting at specified point

[vaijpc]

I want to run a timechart 'overnight'... e.g. getting the minimum values of a field between midday and midday... 12-12

If I wanted minimum values between midnight and midnight, 0-24, it would be easy, just timechart foo span=1day. I don't know how to offset it by the 12 hours required though.

I guess I 'could' use span=12h and then manually look at the minimums of the 12-24,0-12 but that means then grouping those and taking the minimum... possibly manually...?

Run it at midnight for the last 36 hours and do this:

...  earliest = -36h@h latest -12h@h | timechart span=1h min(foo)
