Hi Jia-Hung,
Oh, looks like I am wrong -- I am sorry. Can you open an issue? For
now, a projection might get you closer to the type of exploration
you're looking for, but I will look into adding a coordinate for the
slice.

Ben Keller, Sam Skillman and Nathan Goldbaum were working on a widget for IPython that would provide something like htat. For specific positions, you should be able to specify the coordinate of a slice, but it's not possible right now to do it more generally during the course of the exploration.
