Error with LaTeX formatting in figure legend

When using the LaTeX interpreter, the square brackets interfere with the the formatting of the characters within the legend, specifically reverting the subsequent characters after \mu to normal text. In the title, I used $$ to separate the greek letter but this doesn't work with the square brackets. Any help appreciated.

set(0,'defaulttextinterpreter','latex') %set default font to latex

figure
grid on
plot(v,xi1,'-bo',v,chi1,'-.rx',v,psi1,'--kp') % Plot data
legend('\xi [\mum]', '$\xi {[nm]}$','Location','southeast');% Generates legend
xlabel ('Velocity [m/s]', 'fontsize', 12);% Titles x-axis
ylabel ('Metrics [Dimensionless]', 'fontsize', 12);% Titles y-axis
grid on;% Turns grid on
title ('For $\mu$ m-scale Ti', 'fontsize', 14);% Titles plot

Result:

EDIT: I have come across an answer here.

legend('$\xi$ [$\mu$m]', '$\xi$ [nm]','Location','southeast');% Generates legend
set(legend,'Interpreter','latex')

But now I've come across a similar issue... How to set the axes values to LaTeX font?

See if substituting: \left[ for [ and \right] for ] improves your result. It worked when I experimented with it:

legend('$\xi \left[ \mu m \right]$', '$\xi{\left[ nm \right]}$', 'Location','southeast');% Generates legend

See: The Not So Short Introduction to LaTeX2e (link) P. 60.

Thanks for the suggestion, I've actually implemented a solution you previously suggested on another post as shown in the edit of this post!

I'm now having difficulty in setting the axes values to the same font. Do you know how to solve this?

My pleasure.

I don’t understand: ‘setting the axes values to the same font’. You probably need to define that specifically using Axes Properties (link). I’m not sure what to point you to, since I don’t understand what you want. (The LaTeX font options in MATLAB are limited.) One option might be 'FontName' (link). You’ve already set 'latex' as the default interpreter, however if you need to set that specifically, use the 'TickLabelInterpreter' (link) property.

Apologies, I meant the tick font. I chose the font that most closely resembled what I wanted:

set(gca, 'FontName', 'Palatino')

Thanks again for your help!

As always, my pleasure!
