Problem

I need to display an image volume with multiple slices, similar to sliceViewer in Matlab. However, the current imshow function only supports RBG(A) or 2D scalar data.

Proposed solution

The code example here shows how to display multiple slice images, but there is a lot of code to write, which is not convenient. Maybe one solution is to provide a wrap function (i.e. imshow_3d or slice_viewer) that implements the example code somehow?
