1. Content Align is used to make alignment on legends in AIV widget, the content align contains options of None, Left, Center and Right. User choose the direction and the legend takes that place in widget.

2. The Position control is dependent on the Content Align control in widget, the position only works in place where the content alignment is located. for example, if the content alignment is in Right (the legend stays in right side of the widget) then the position works in the right side only.
