Is there a way to insert a horizontal line in the figure captions?
I tried with using \line(1,0){3} but I get a long underscore (_) I tried using \raisebox{2pt}[0pt][0pt]{\line(1,0){3}} but I get the following error:
Which I found indicate that latex might be stuck in a loop.! TeX capacity exceeded, sorry [input stack size=5000].
Thanks
