Real-Time Engine (?) Notation When in Live Play

I've started looking in to chess again after a 30 year absence.  I'm using Chess.com as my entry vehicle.

I've noted that, when playing a live game, to the right of the board, there is some sort of analysis engine commenting on each move.  There are numbers and horizontal bars that pop up with each move.  Some of the activity seems to be a histogram.  I have no idea what they mean.

Can someone please refer me to some sort of documentation that defines, in detail, what the analysis engine is telling me as each move is made?

What that is left to right...

Moves.

The longer the status bar, the longer you took to make a move..

How much time was taken  on each move.

Thank you for the courtesy.  I got the moves, I thought the bars might be the "goodness" of the individual move, and I had no idea what the move length numbers were.

Would it be reasonable to conclude that, over these 16 moves, that Black built an advantage and then lost it on move 15?

Really? It's my understanding that those bars represent ONLY the time used.

Compare the lengths of the black and grey bars with the printed times next to them. It's a perfect match.

So no, I don't believe there's any indication at all of who holds the advantage.

I stand corrected (again)  You are correct. 

And I stand corrected as well -- time is presented graphically and numerically; the goodness of moves and position is presented in the analysis ... or somewhere.

Since I was starting from zero, I am perfectly happy with learning some very basics.

Players wouldn't want a computer telling them who is winning anyway... not while the game is still underway.

The redundancy is confusing.

Just think of the conspiracy theories that would begin with, "The engine was telling me I was way ahead and pulling further away, when "Bam!!.  I lost.  It must have been hacked.!".
