Are TWIXT ratings coming back anytime?

What exactly is missing?  I see that your rating is 2080, for example….

I'm referring to the ratings chart that “charts” your ratings movements from day 1.  The little box next to your current rating in the games you play…

Ah, I see.  Thanks for explaining.

I just tested on both Firefox and Safari and the graphs seem to be missing for all games.  :(
