Depending on what the context is for the chart that may confuse people. Suppose we have a vast but very transient influx of editors, say tenfold as much as usual on a smaller wiki, say after a national celebrity confesses she edits Wikipedia. Now in the extreme case where all new editors stay for just one day, that would still yield a high plateau in the chart for 30 days. The same of course would happen in monthly stats. But there people expect this kind of behavior. In daily stats now so much.

A small window of say three days would dampen this effect. Yes it'll be apples and oranges with monthly stats but that may be unavoidable.

Subject: Re: [Analytics] "Active editor" for a given day (instead of month)

We could use a moving 30 day window.  If we update the definition slightly to say that an active editor is an editor that has made at least 5 edits in the last 30 days (effectively what's happening now), we can generate that every day.

Hi,

our current definiton of „active editor” [1]:

  An 'active editor' is a registered (and signed in) person (not known
  as a bot) who makes 5 or more edits in any month in mainspace on
  countable pages.

is centered around months. That's good.

However, as we are seeing requests to produce daily graphs: How to
interpret the above definition in terms of active editors for a given
/day/?

Especially: How to do it in a way that blends nicely with the current
month-based definition?

Best regards,
Christian

P.S.: I've seen code in our repos that just looks for edits of the
last 30 days. That sounds nice. But if I am doing 3 edits on
2013-07-01, and another 3 on 2013-07-31, I would not be considered
active editor by this daily approach for any day. However, I'd be an
active editor for July using [1] :-/
