I would guess that the author is trying to show when they've deliberately overruled the cameras exposures settings.

So in the section on under exposure the exposure compensation gives an idea by how much the image was under exposed.

Which IMHO is useful to know.

Yeah...that was what I was going for but the parent comment has a point, one which I did t really think about until I started collecting photos and noticing that some of the photos didn't match expected EV...I had thought that the EV reflected what the camera registered, no matter what mode I was in...but of course, it only measures compensation, which will be wrong if the photo is taken and the EV doesn't match the EC. And since I've just confused myself trying to explain this I doubt it's clear to the average reader.

It would be pretty easy to generate histiograms with Imagemagick...that is probably more useful
