Hi guys

I having trouble interpreting a GCMS graph. How do you read them? along the bottom is time, up the side is %area. On top of the different peaks there are two values, one is time, and the other is area I guess. But I don't understand what use this has? A peak at 7minutes with a size of 80168 doesn't mean a lot to me
