Understanding User Stats and Graphs

I just joined chess.com. I'm looking for a reference guide that explains user stats, graphs, etc. I've looked through the FAQ's but haven't found the information. 

There isn't anything.

Fortunately, most of it's not hard to understand. You just joined. You've played only one game. 

Your blitz rating is 778.

Tomorrow, you will start having a history, which can be graphed.

The Glicko RD is a measure of how accurate your rating is. Your 254 means there is a statistical prediction that your rating falls in a 1016 point range, 508 points above and below its current level. (2x the RD)

How am I wrong?  I just meant that the graphs and averages would start filling in. 

1 blitz game doesn’t show stats. Notmtwain is right. 

Understanding the play graphs. white grey black with percentages what does any of that mean? When you look up openings it shows a list of moves with a bunch of statistics or percentages, what do they mean how do you use and understand them who is the grey guy? White and black are what, win/ losses?

Yes, win/loss/draw percentages of games that had those positions, though opening choice in most cases isn't the cause of the results. White is for white wins, black for black wins, gray for draws.
