I would like to make clear from the start that I don't have the matlab script that produced these .fig, so answers concerning Matlab configurations might not give an answer (although accepted as future advice). In addition, the time pressure I have for my project is enormous.
I have almost 50 .fig produced from Matlab and their corresponding .eps files.
I am using Xelatex + subfiles package, Texmaker, MacTeX. The .eps files look GREAT when previewed as files. But when included and compiled in Latex, there are no axis or labels (or any font-related stuff). I looked around for solutions but most answers are suggesting matlab related modifications when producing the figure. Some also mentioned that if compiled in a different system under the same settings, the problem does not show up. That is why I guess a MWE won't be useful.
I do have Matlab installed if urgently needed.
EDIT: I found out that the problem has to do with the font of matlab which is NOT set to interpreter: latex. If I go and change the matlab figures' label property to
'interpreter','latex', it shows the labels. But still, I have to deal with the axis and legends x49 more figures :P
