I ran a WiFi survey using "Wifi Analyzer" freeware on my Android phone in
a college-dorm atmosphere earlier today (after installing Windows 10),
and I think I completely understand the 2.4GHz wifi signal-strength
chart; but I totally fail to gather any useful information out of the
5GHz signal-strength chart (specifically what band to set the 5GHz wifi
adapter to).

The 2.4GHz chart is at the left; while the 5GHz chart is to the right.

While viewing the 2.4GHz chart, tap the screen once. You'll see a freq band
indicator over on the left, near the -db scale. If you do nothing, the freq
indicator times out and disappears again, but if you tap it while it's
visible, the screen switches to the 5GHz band.

What you're calling the 5GHz chart is really just another view of the 2.4GHz
chart. You *swiped* to get there. You need to tap.
