[mrtg] Re: Graph overlapping?

Thank you!  I did notice that the graphics for both Thurs were different, so
I knew it was 2 different Thursdays.

Thanks again.

There are four types of graphics: daily, weekly, monthly and yearly
graphics.  They work on 5-minute averages, 30-minute averages, 2-hour
averages and 1-day averages.

The graphics are 400 pixels wide (by default) and will display:
400*5 minutes  == 1 day + 9 hours + 20 minutes
400*30 minutes == 1 week + 1 day + 8 hours
400*2 hours    == 33 days + 8 hours
400*1 day      == 1 year + 35 days

You are therefore not seeing thursday twice, you are seeing two different
thursdays.

As you can see, there's nothing to fix.  If you want to display exactly
one week, you need to create pictures with width 336. This will then
also display 336*5 minutes == 1 day + 4 hours and so on.

cheers,
