There is a problem here. To many people, the histogram is the
two-dimensional image displaying the bins as vertical bars.

This is wrong, of course, but we have to face reaility: if we pretend that
the histogram is an image (which RandomAccessibleInterval suggests despite
the name -- which exposes the nationality of the ImgLib designers, by the
way), people will assume it to be that two-dimensional image and be
surprised to find it is one-dimensional.

Just cautioning here.
