There is nothing like this currently in Octave but it had been a while since I wanted to give it a try.
I attached a draft function that should do what you want. It only works when there is a single axes in the figure and only points to line objects:

plot (rand (20, 4)

h = datacursor ();

%% get the coordinates of the data cursor

x = get (h, "x")(2);

y = get (h, "y")(2);

I attached an updated version, the previous one had problems in the displayed coordinates and didn't handle log coordinates.
