I have used chinagraph pencils in several situations.
In the 70s and 80s in the navy - blue or black to update status boards that could be rubbed off when required as things changed. These could be of many sorts: current call-signs, radio frequencies, base course when zig-zagging etc. Probably these days a dry-wipe marker pen is used.
As a navigator I used yellow and white to draw on radar screens for calculating closest point of approach to other vessels, our relative position in an escort screen, keeping a safe distance off shallow water etc.
And most importantly, marking on a mug which was my tea or coffee. (on a busy bridge it was easy to pick up somebody else's!)
Also, like Magnus, writing details of race courses on the deck of my dinghy, but not where you were likely to rub it off accidentally as you move about!
