What going on with my graphs?? - Standard installation, nothing fancy, all the data looks good but my average/min/max graph looks like a saw!! Can't be right from what it says. Can only think it's drawing it wrong. Welcome to suggestions. It can be seen at http://www.Birlingham.com

I can't get your site to load.

The min/max/avg temp graph is drawn from the data in dayfile.txt, so if there's a problem, that's where it will be. If you have a look in there, it may be obvious to you, or you can attach it here.
