How to set different colors for the text in a legend ?

Hi

I am using MATLAB 2015. I followed the post >https://se.mathworks.com/matlabcentral/newsreader/view_thread/73336> to set different colors for the different text but still it does not work. According to the link, my hText is empty and h is 1 x 1 legend, but it has more than 1 string. Whats the possible solution here ?

Use TeX formatting to set the colors.

x = -pi:pi/20:pi;
y1 = sin(x);
y2 = cos(x);
plot(x,y1,'-ro',x,y2,'-.b');
l = legend('\color{red} sin(x)','\color{blue} cos(x)');

You can also set the color using RGB triplets with

\color[rgb]{0,0.5,0}

Sorry, probably I was not clear. But in the example above, I want to set red for 'sin(x)' and blue for 'cos(x)'. In other words, different colors for the text.

Use TeX markup! See here under Text -> Interpreter.

x = -pi:pi/20:pi;
y1 = sin(x);
y2 = cos(x);
plot(x,y1,'-ro',x,y2,'-.b');
l = legend('\color{red} sin(x)','\color{blue} cos(x)');

Thanks. It was helpful. As I have many entries in legend, how can I specify color from RGB Triplet e.g. [0,0.5,0] ?

\color[rgb]{0,0.5,0}

It's on the doc page under TeX markup.

How can this be done with/under LaTex interpreter?
