In your actual use case, are there any annotations outside the panel
(tick marks, labels, etc.)? Things would be much simpler if not (as in
your example). In that case, just call the suitable panel function
after setting up the proper axis limits (after doing pushViewport or
seekViewport or whatever).

If you do have extra annotation, you need to decide how much space
they should have.
