Use latex with bar command in categorical array

Hi I would like to insert Latex text in the part of this graph that i've underlined instead of the one that is already there. Does anyone know how? Is it possible?

Thanks in advance.

The main code, if necessary, is the following

xx=diag(critAng2);
figure
barX=bar(ca,xx,'stacked');
ylabel("$\theta_c$",'Interpreter','latex','FontSize',12)
hold on
%Teórico
bar(ca,TEO,'FaceColor','none','EdgeColor','k','LineWidth',0.8);
grid on
legend([ERR,"Teórico"],'Location',"northwest")
legend('boxoff')
title("Angulo Crítico",'Interpreter',"latex")

This should work:

set(gca,'xtick',x,'XTickLabel',s,'TickLabelInterpreter','latex');

Above, x contains the tick values and s is a cell array containing the tick labels with latex syntax. As an example, with s initialized as follows:

s = {'$\it{Label\ 1}$', '$\pi r^2$', '$\textbf{Label\ 3}$', '$\frac{foo}{bar}dy$'};

the bar chart x-axis tick labels appear thus:

thank you so much! this worked :'D and well in my case I had to use x = b.XData where b stores bar.
