Missing label on first marginalisation about corner.py HOT 2 CLOSED

This is the expected behavior! The y-axis on the top left plot isn't in units of "label 1" and I wouldn't expect it to have that label. If you feel that you want to identify that subplot, a good approach is to use titles (i.e. the title of the top left subplot would be "label 1").

Ah, I see now! I interpreted the labels more as a labelling of the column or row of plots, rather than an axis label. With that view in mind it seems weird that one is missing. But I can also understand the other point of view, and it makes sense that the default is to not have this label there.

One can add it easily on their own to the returned axes like so: (for reverse = False and labelpad = 0)

ax = figure.axes[0]
ax.set_ylabel("label 1")
ax.yaxis.set_label_coords(-0.3, 0.5)
