I was just thinking of adding the wet-bulb to the data. There's a pretty long calculation I need to type in to get it. I don't think I can overlay plots. I'm using some javascript functions that I found for free on the internet to draw the graphs. There isn't to much customization you can do with them that I can see without digging into their scripts and hacking stuff up. I know the scale is confusing, I should have clarified. The labels need to be small due to the way the script works. So I stripped out the minutes from the time stamp to populate the labels. When you see a 00 thats the start of a new hour, say 10 am. The next label should be a 10 or so, that would make it 10:10 am. Next a 20 for 10:20 am and so on. As noted the graph starts at 01/09/2007 15:01:36, which is when I started collecting data. You'll see the first few readings were pretty close together (01, 02, 03, 03) since I manually ran the script a few times. It also notes the end time stamp at the top so you can count back-wards from the end to figured out where in the chart you are.
