Plot 2D with Annotation

Hi MATLAB Experts,

I am creating 4x2 subplot. By using fints, how can I set different color for each line as follows: Blue / Red / Dark Green..

Also, I'd like to have annotations (text box) to show data for last observations for each line. Please share your thoughts!! Thanks in advance!

for d=1:8

    index(d).sum = [plotdate indexA(:,d) indexB(:,d) indexC(:,d) ];
    index(d).fints = fints(index(d).sum);
    subplot(4,2,d);
    plot(index(d).fints);

end

Best, Jake
