The usual form of histogram has equal-sized bins, which doesn't match very well with a spectrum which spans an infinite range in theory, and in practice from, say, 100 MHz to perhaps maybe 100 EHz.
If you want non-equi-spaced bins, then a histogram is surely much the same as a list of intervals, with the advantage of the latter that the "bins" do not have to be contiguous. So for instruments with sensitivity in two or more non-adjacent bands (e.g. XMM-Newton with optical and X-ray telescopes) you can simply have two intervals. Expressing that with a histogram is more messy, but does not really contain any more information. But perhaps I mis-understood your proposal (since I didn't have beer with my lunch, unfortunately).
