The daily plots show data for 36 hours leading up to the most current 
data available at the time Orca processed the logs.  If you see two 
daily graphs, one at 12:00 and one at 18:00, then those two graphs 
probably also have a different "Last data entered at" line (at the 
bottom of the image).  That could be a sign that one of your hosts isn't 
updating, or that the regular Orca processing (if you have it set up to 
run only every so often) did not run or did not complete for that host.  
It may well be possible you just caught it after it processed one host, 
but before the other.

Note that the oldest time printed on the axis for the daily graph is on 
the 6-hour mark, but the oldest time represented in the graph is "Last 
data entered at" time minus 36 hours.

The weekly graphs go back 10 days, the monthly graphs go back 6 weeks, 
and so on.  This is hard-coded in Orca in the 
"lib/perl/Orca/Constants.pm" file.

Hope this helps!
