This was the main point of confusion on the first round of feedback, how the breakdowns would work. You can explore this in the prototype on the [https://analytics-prototype.wmflabs.org/#/contributing/active-editors Active Editors metric]. Toggle the breakdown button and check/uncheck the various checkboxes. You can also change the graph type to "table" and see the same thing. Does this work the way you'd expect or is it still confusing?

Do breakdowns make more sense when you can see the graph change?
I could "intuitively" understand it (before reading this).
The only thing I found difficult is that categories like "lightly active" seem rather opaque to me, and even if I could read what it means I would be much interested in seeing small multiples of histograms or any other standard visualization of more raw data than predefined categories.
I assume it was a conscious decision to make the different sections of a metric mutually exclusive. I'm not sure yet whether I like it, but for sure it's different than Wikistats 1.0 Could that raise any confusion? In Wikistats 1.0 the figure for 5+ editors does include the 100+ editors.
I did not mind it being mutually exclusive (this is rather what I expected knowing histograms etc.); My concern was that I was unsure what "lightly active" actually means and that I got a predefined splitting point to the next data bin (which would be medium active, or something like this)
This is, indeed, not something we're fully decided on how to handle. With mutually exclusive breakdowns we have the flexibility to show 5+ or 5-100 as we wish. So we're writing the back-end this way and then we are planning two interfaces. One is the one you see, and we're aiming for "easy to understand". And another is a flexible "big table" that we hope can handle most of the big table use cases possible in Wikistats 1.0. In that scenario, you will be able to get 5+ editors and any other kind of metric you might be interested in, and save bookmarks for it.
