x and y axis labels

xlabel('Gr^*\it\bf_x','FontWeight','bold','FontName','Times New Roman','Fontsize',12); ylabel('Nu\it\bf_x','FontWeight','bold','FontName','Times New Roman','Fontsize',12);

Instead of Nu_x or Gr_x I want Nu_x bar or Gr_x bar as axis title in MATLAB graph. What change do I need to do in the following lines?

Answer 1

[Matt Fig]

I am not sure why this doesn't work, but the latex for a bar is:

'\=x'

that is, according to: Latex cheat sheet

I tried to first set the interpreter to latex, then do this:

set(L,'string','R_{\=x}')

But I got the old, 'unable to interpret string' problem.

The documentation says that MATLAB supports full Latex, so I don't get it.

[Matt Tearle]

Ah, the old LaTeX interpreter trap. Is this what you're after:

xlabel('$G\bar{r}_x$','FontWeight','bold','interpreter','latex');

The trick is the use of the $ signs to set it as an equation.

BTW, it doesn't seem possible to put the bar just on the x (ie on the subscript).

EDIT TO ADD Matt Fig found the right combination of TeX and curly braces to get a bar on a subscript: (Copied from comments below)

xlabel('$$G_{\bar{x}}$$','FontWeight','bold','interpreter','latex','fontsize',20)

[Matt Fig]

I think the OP wants the bar over the x subscript. Those $ get me every time!

[Matt Fig]

It sure is:

xlabel('$$G_{\bar{x}}$$','FontWeight','bold','interpreter','latex','fontsize',20)

[Oleg Komarov]

I don't get why overset is not supported...the bar is too short, or too long if overline instead of bar is used:

xlabel('$Gr^*\it\bf_{\bar{x}}$','fontw','bold','fonts',16,'interp','latex');

ylabel('$Nu\it\bf_{\bar{x}}$' ,'fontw','bold','fonts',16,'interp','latex');

[Matt Tearle]

@Matt F: Graargh. I thought I tried that permutation. Not enough curly braces, perhaps.

Anyway, nice work.
