# How to include a character with a macron (horizontal bar) in a legend?

42 views (last 30 days)
I am trying to put a macron over an "s" in a legend string. I have tried LaTeX syntax, but it does not work. This is my code:
hLegend(3) = legend([h1, h2, h3], ...
'\it{r_{123}}', ...
'| \it{r_{123}} |', ...
'\it{$\bar{s}$_{123}}');
set(hLegend(3), 'interpreter','latex');
And this is the warning I get
Warning: Unable to interpret LaTeX string
"\it{r_{123}}"
Warning: Unable to interpret LaTeX string
"| \it{r_{123}} |"
Warning: Unable to interpret LaTeX string
"\it{$\bar{s}$_{123}}"
Any idea what I could be doing wrong?

Workaround as described in NG: Matlab and Latex
plot(1:10)
h = legend('$\bar{s}$');
set(h,'interpreter','Latex','FontSize',18)
Thanks, that works

Complementing Oleg's answer, I include one of the workarounds he suggest.
Thank you very much
