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}
