Hello all,

I have a plot with 4 different colors, the problem is that I don't know in which order the colors are being printed (and it is a bit hard to save the order). Is there anyway to make legend like this:

legend(color1,str_legend1,color2,str_legend2,color3,str_legend3,color4,str_legend4)?

The code:

for kk = 1 : length(vec_ray_angle)
    if (shuffling_significance(kk) <= parms.shuffling_significance)
%                         scatter((ax_bins(kk) - delta),vec_ray_angle(kk), 'g', 'fill'); hold on;
        if (sum(kk == idxs_slices_far_from_wall) > 0)
            % dark green
            vec_color = vec_dark_green;
        else
            % bright green
            vec_color = vec_bright_green;
        end
    else
%                         scatter((ax_bins(kk) - delta),vec_ray_angle(kk), 'k', 'fill'); hold on;
        if (sum(kk == idxs_slices_far_from_wall) > 0)
            % dark blue
            vec_color = vec_dark_blue;
        else
            % bright blue
            vec_color = vec_bright_blue;
        end
    end
    plot((ax_bins(kk) - delta),vec_ray_angle(kk), 'color', vec_color); hold on;
    text((ax_bins(kk) - delta),vec_ray_angle(kk), num2str(round(vec_ray_angle(kk))), 'color', vec_color);
end
