ng:attr:x="{{($index * 4)+10}}px"
might help as quick fix but it's not correct solution.
I'm at work at the moment and cant really check it out. But I'll check it at the evening
. I haven't updated dashboard for my working unit so I never run into this. But I will check out If something needs or can be improved.
Actually I should start to create proper UI node for this but yeah, too busy for that at the moment.
