Three dots accent above a symbol in the label of the figure ??

I want to write in the label of my figure a symbol with three dots above the symbol (representative of the third derivative). I know that is possible to create a symbol with two dots above the symbol through the latex interpretation for example xlabel (${\ddot{\phi}}$,'Interpreter','latex') but the function xlabel (${\dddot{\phi}}$,'Interpreter','latex') in order to have a symbol with three dots above doesn't work. Do you know there is any way to do it ?

This worked for me

figure()
xlabel('$\stackrel{...}{x}$','interpreter','latex');

I don't think

\dddot

exists in LaTeX itself. You could try

\overset{...}
