I'm experiencing a weird issue on one of my graphs. I am showing data at one minute intervals.. when I view the chart for the last 12 hours, the values are wrong when comparing them at 6 hours.

A friend who also has the same chart says it isn't happening to him, and that it shows the correct values no matter what zoom range. I've tried on several different browsers, and I still experience the same problem.
What could it be?
