By default MRTG will show 400 pixels equals 400 * 5 minutes or 33 hours
and 20 minutes.  If you reduce that to 10 hours which is 10*60/5 pixels
you will get an average over this 10 hours.  Read the averages at 18:00
and you have what you are looking for.

I can't remember the exact option for this but I'm sure that if you go
through the config.txt file and look for "size" you'll manage.
