DataAspect for an axis and setting the limits manually, it is not uncommon for an axis to not fill all the space at its disposition. As far as I know this is unavoidable since in this case the aspect ratio of the layout space and of the axis are chosen independently.
However is there a way to align the axis along one of the border, instead of having centered in its allocated space?
For example in the following I would like to have a 0 gap between the rows, by aligning the top axes to the bottom of their allocated boxes and the bottom axes to the top of their. Having a bit of extra space on top and bottom in this case is in this case less of a concern than a gap in between.
