Board Game Arena

Hi,

Can anyone explain me what is the meaning of the histogram we can see below the menu when in arena mode ?
Here is what it looks like today (2021/04/01) :



I find it quite ugly, mostly because I can't understand it.

Thanks for that site anyway, for the good work, and the regular new games !

I believe it is showing the progress of the current arena season. IE, how many days of the season have passed, and how many days of the season are still remaining.

It shows the average number of arena games for that day, I guess.

It is a percentage as far as I could see in the source code.

Is that the percentage of games not in arena in all games of the day ?
But why showing such a percentage ?
