Raymarine i70 wind history

Hi everybody.

I've just installed a Raymarine i70 on my 32' sailboat. Luckily, everything is working fine.
I'm trying to understand the "wind history" frames (TWA, TWD, GWD), as they show some figures that I do not understand: there is a "moving" bar graph together with three numbers at the right of the screen.
On top is the "actual" wind direction, but the other two are confusing me. First I supposed that they were "maximum" and "minimum" recorded wind angles, but they do not change following the new max/min showed, so I'm not certain about them.
Besides, the graph bar moves up and down, supposedly towards the average wind direction (??)...
My question is: 1) what are those numbers; 2) is the horizontal axis showing the average wind direction?
Thanks in advance for your help!
Best regards
