Matlab: list of overlay legends and legend overlapping graphics after saving

Question

I am trying to reverse the order of the legend entries based on the reverse color order of the legends in the matte cap of the capital letters , but this does not seem to work in my case.

Basically, I have a GUIDE figure that draws a lot of plots and can save them in a .png file. The effect looks like this:

I managed to change the order of the text by turning the legend upside down, but I can’t change the order of the colors of the legends. Here is what I have:

[a b] = legend(legenda);

map = colormap; % current colormap

n = size(b,1);

z = linspace(size(map,1),1,n/3); % there is 1 text and 2 line elements for every data series, so I divide by 3

z = round(z); %otherwise matlab gets angry that indices must be real integers or logicals

MAP = map(z(:),:); % gets elements specified by linspace from colormap

So far, everything is working fine.

Vector b for two episodes looks like this (starts with 2.0 because it changed):

Text    (P+C 200 2.0.dpt)
Text    (P+C 200 1.0.dpt)
Line    (P+C 200 2.0.dpt)
Line    (P+C 200 2.0.dpt)
Line    (P+C 200 1.0.dpt)
Line    (P+C 200 1.0.dpt)

So, I realized (based on the linked code), I need to change the color variable for each row entry.

for k = (n/3 + 1):n
   a1 = get(b(k),'Children');
   set(a1,'FaceColor',MAP(ceil((k - n/3)/2), :));
end

Ceil and dividing by 2 gives the same index twice.
