Hi everyone,
I have a legend with different text color, and I wanted to apply Latex markup.
I have the code shown below and it is working. However, when I set the Interpreter to be Latex, it doesn't work at all.
Is there any mistake I have made?
l=legend('\color[rgb]{0.9 0.9 0.9} S=0.8, AR=0.25');
%% set the Interpreter to be Latex
set(l, 'Interpreter', 'latex')

From the doc on 'Interpreter' property linked to from text documetation:
LaTeX Markup
To use LaTeX markup, set the Interpreter property to 'latex'. Use dollar symbols around the text, for example, use '$\int_1^{20} x^2 dx$' for inline mode or '$$\int_1^{20} x^2 dx$$' for display mode.
The displayed text uses the default LaTeX font style. The FontName, FontWeight, and FontAngle properties do not have an effect. To change the font style, use LaTeX markup.

I dont think it is possible to change the color with the latex interpreter. It can be used to make text bold for example and insert symbols. i would change the color like this:
legend('\textbf{test}','TextColor',[0 1 0],'Interpreter','latex');

Hi there,
This is working even without
\textbf
However, my legend has 9 inputs and 6 of them need to be in grey and the rest will be in black color. That is not working anymore if I input more than 1.
Thanks

"... legend has 9 inputs and 6 of them need to be in grey and the rest will be in black color. That is not working ... if I input more than 1."
'TextColor' is a single global property for the legend handle, there isn't the facility to have multiple values for a single property.
And, there's no facility to add more than a single legend to a figure/axes so you're stuck on that one.
An alternative would be to use annotation or text objects to write the strings, not legend
