How can I change the color of each stack in stacked bar plot?

Hi,

I tried many ways to make this works. Unfortunately, I could not find any way. I have want to draw a stacked bar plot using barh and change the color of each stack individually, as I mentioned in the picture. For instance change the color of the first bar as black, blue, white, and so on. There is no specific pattern. Is it possible to make access each stack color? I warmly appreciate your help in advance.

%Create a stacked bar

h = bar(X,'stacked');

% Set bar colors

set(h,{'FaceColor'},{'g';'r'});

Thanks for your response. This does not work. The problem is that there is not a specific pattern for colors. In other words, one bar is for example red, blue, black. while the other one is black, red, blue. Using what you suggested all first stacks of ALL bars would be green and the second stacks of all bars would be red and so on(if there are more stacks)... But I want to control the color of each stack in each bar independently. I think the solution might be in CData (after matlab 2017b).

An example with my data

barra = bar(1:1:20, cuentas3, 'stacked')

barra(1).FaceColor = 'c'

barra(2).FaceColor = 'y'

Hello Vahid,

I do not know if you found a solution to your problem but I had a similar issue and I found that post without the use of CData:

It is kind of tricky but helped me for my application. For your application I guess it should work even though having several classes will make the code a bit longer.

Below a "reduced" code of the example found in the link above:

data =[
    8.5000    NaN       NaN
    3.0000    10.0000   NaN
    5.0000    NaN       NaN];
data_class={
    'c'   ''     ''
    'g'   'gc'   ''
    'c'   ''     ''};
data(end+1,:)=NaN;

figure;
b={bar([1 2],data([1 end],:),'stacked')};
hold on
for k=2:(size(data,1)-1)
    b{k}=bar([k-1 k],data([end k],:),'stacked');
end
for k=1:(size(data,1)-1)
    for k2=1:size(data,2)
        switch data_class{k,k2}
            case 'g'
                set(b{k}(k2),'FaceColor','g')
            case 'c'
                set(b{k}(k2),'FaceColor','b')
            case 'gc'
                set(b{k}(k2),'FaceColor','c')
        end
    end
end

Hope it will help!
