Perhaps your are correct for the original reason for collecting this data. But actually, I find it very important and interesting that connections tend to have bursty writing more often than bursty reading! > I also > aggregated observations similar to Torperf measurements, by plotting > only median and interquartile range.

Do you have further ideas for improving it? I do like the new graph, its much cleaner than the old one. But I like the mostly reading/writing parts of the old one too. Maybe we can create two more graphs like the new one (1 for mostly reading and 1 for mostly writing). I also think a stacked percentage area graph (e.g. http://www.highcharts.com/demo/area-stacked-percent) could work here, as a way to get all the data on the same chart. > > This graph is only there to show what kind of data we have.

But I think an important subgoal is also to have graphs that make it clear how the data is useful, not only that it exists. Perhaps keep both/all versions?
