I would like to know if there is a way to produce symbols like a "gamma over dot" (or any other sign with a point above) in graphs, e.g. as axis title. In this special case I would like to avoid dgamma/dt [d\g(g)/d].
I had a similar question a while ago and the answer was
"We have built-in support for above bars and dots using escapes sequences. If you open Text Object Properties dialog and type this: Bar above \ab(text). Dot above \ad(text). You should be able to see bar and dot above "text" words."
If you open Origin help (menu: Help->Origin) and search for the phrase: Escape Sequences You will find topic by that name that lists all escape sequences.
