I have a set of billboard JS charts on a page, in a bootstrap row and column grid layout. So all the 'cells' of this layout have the same width. But billboard is deciding how much width to give the axis labels. Ideally what I'd like is to be able to force-set the width of the vertical axis label width so the charts line up nicely when stacked on top of each other.

So far, I haven't been able to find a way to set the width of axis labels in billboard JS. Would love some help if someone knows how.
