Hi All,

I been working on graphs to visualize the entire edit activity of in wiki for some time now. I'm documenting all of it at https://meta.wikimedia.org/wiki/Research:Editor_Behaviour_Analysis_%26_Graphs.

The graphs can be viewed at https://cosmiclattes.github.io/wikigraphs/data/wikis.html. Currently only graphs for 'en' have been put up, I'll add the graphs for the wikis soon.

Methodology

The editors are split into groups based on the month in which they made their first edit.
The active edit sessions (value or percentage etc) for the groups are then plotted as stacked bars or as a matrix. I've used the canonical definition of an active edit session. The value are + or - .1% of the values on https://stats.wikimedia.org/

Selector

There is a selector on each graph that lets you filter the data in the graph. On moving the cursor to the left end of the selector you will get a resize cursor. The selection can then are moved or redrawn.
In graphs 1,2 the selector filters by percentage.
In graphs 3,4,5 the selector filters by the age of the cohort.

Preliminary Finding

Longevity of editors fell drastically starting Jan 06 and has since stabilized at levels from Jan 07. https://meta.wikimedia.org/wiki/Research:Editor_Behaviour_Analysis_%26_Graphs#Preliminary_Results

Would you to hear what you guys think of the graphs & any ideas you would have for me.
