Good day. I wanna link Bars in small group with one general parameter - fade. Here small vision about what i want:

Edit for Actionbar 2

If [Bar:1] fade:0; [Bar:3] fade:0 then
[Bar:2] fade:0
elseif [Bar:1] fade:100; [Bar:3] fade:100 then
[Bar:2] fade:100

Main concept - always fade effect wherever whatever, but when I mouseover one of them for show it, both other will show too. When i moveout mouse from one of them, both other will hide too.
