Following your suggestions, I have redirected the enwiki page for WikiXRay to meta (discussion included...).I have also uploaded additional graphics.
Interesting points are results for the evolution in time of Portuguese version (perhaps the bot factor) and the different author per page length graph for the French version (do you notice the bottom left side... it is almost empty) :- )
Remaining results for English Wikipedia are being cooked rigth now.
I promise new research graphics in the near future. Hope you enjoy them!
