Not convinced the histogram tooltips are useful
Mostly they just seem to get in the way. Ideally they'd be toggleable? But I'm guessing that if there isn't already a button for that it's not really possible.

So, it turns out that they can be disabled, but currently it requires some menu wading.
One has to find the overlaid "?" icon corresponding to the pad the histogram is drawn in (there are usually more than one, so it's the smaller one; see red arrow in the attached image) and click it, then click the
TFrame:: item (illustrated in attached image), then, in the menu that pops up, there will be a "Show tooltips" toggle.
