These shouldn't be needed, maybe axes because you mutate them.

While trying to reproduce the bug in bqplot I noticed this resulted in my axis not being visible most of the time, maybe the test in the line above is faulty?

This is a follow up to #2647 that would overlay the preview spectrum on whatever the current zoom is, with an additional y-axis on the right to show the flux of the preview spectrum. Currently blocked by a potential bqplot bug, where the axis tick values are not updating when the axis scale updates.
