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
Thanks in advance.

Do I understand correctly that you have a lot of lines, but only want to have 4 legend entries which need to be of different colors?
Why not just generate four dummy points (outside of your figure), one of each color, before the loop? Even nan or inf points would work.
If that doesn't work for you, which version of matlab are you using?
Cheers
