I have a figure that is composed of two columns. Each column is itself a GridLayout. I am having the problem that on the right end of the figure, the axes labels go over the figure boundary:

How do I fix this? I don’t want to change the figure padding, because the left side is fine. I tried
colgap!(fig.layout, 2, 10.0)
but this doesn’t work as the figure has only 1 gap.
