  • I am not certain what you want.
    Try this:
    errs = rand(1,10);
    x = 1:10;
    y = randi([10 20],1,10);
    plot(x, y)
    hold on
    heb = errorbar(x, y, errs, '.');
    hold off
    heb.LineWidth = 2;
    The error bars and the caps are both linewidth=2 here, with everything else being the default properties.
