How do I hide floating text in fog of war?

[trees123]

And is it possible to do it in GUI? I've tried searching for an answer, but couldn't find one. Please help me.

Well, the simplest way to do this would be to make the text black (For you-haven't-been-there fog).

Unless you don't want it showing when you've been somewhere but you can't see there anymore (For out-of-vision-range fog).
