opposite property
Defines the position of the scrollbar. By default, it is positioned
on the opposite of the main axis (right side of the chart).
However, in the case of RTL languages could be set to false
which positions the scrollbar on the left.
Works only for vertical axes. This means yAxis in a non-inverted chart and xAxis in the inverted.
