A related, hopefully, question: what do the bars in the chart represent? Total bytes transferred within the timeframe that bar covers? Or average number of bytes transferred per hour?
If that's the case, I should take the above chart as, "bytes transferred" from 6:00 to 11:59 on March 18 were 7TB total.
Yet if I zoom in on this same chart, the total of the bars in that same time period represent about 42TB: from 6am to 11am, the values on the bars are 4.1, 5.8, 3.6, 5.6, 11.9 and 10.8TB, totaling 41.8TB.
Does this mean the bars in the top chart aren't "total bytes" for each timeframe a bar covers, but rather, "average per hour"? If so, shouldn't the chart's title say exactly that, "average per hour" rather than "total"?
