My language was imprecise. I cleared the axes of the axes on the 2nd figure. But I explicitly specified that axis:
So it shouldn't touch any handles of patches that are associated with the primary axis, or so I would assume.
And yet, I have an array of 500 or so handles to patch objects that are all children of the primary axis. If I do:
