But as you can see it is not (or I There are no values in the graph. There are rates in the graph. I focus on the big bars only. I see three of them, somewhere around 182u, 141u and 58u. These are rates: {something} per second. Each bar is valid for an hour. So, 3600 x 182u + 3600 x 141u + 3600 x 58u = 3600 x (182u+141u+58u) = 3600 x 381u = 1371600u = 1371.600m The rest is due to the rates I ignored, and perhaps some rounding differences. The main thing to remember: you are watching rates, not values. You are adding surface, not height.
