anyway to give separate color to 'stack' bar plot

Hi:

I read an post from link below:

https://www.mathworks.com/matlabcentral/answers/175955-how-to-assign-a-label-to-each-bar-in-stacked-bar-graph

which provide a way to add annotation to the individual of each data. I would like to know if there is anyway to control the color of each individual bar?

Thanks!

Do you have colors you want to paint bars into?

for i = 1:length(hBar)
    h1 = get(hBar(i),'Children');
    n = length( get(h1,'FaceVertexCdata') );
    set(h1,'faceVertexCdata',rand(n,3))
end

Hi:

thanks for your reply. I get an empty output by using:

h1 = get(hBar(1),'Children')

but the output of hBar(i) is not:

  >> hBar(i)

ans = 

  Bar with properties:

    BarLayout: 'stacked'
     BarWidth: 0.8000
    FaceColor: [0 0.4470 0.7410]
    EdgeColor: [0 0 0]
    BaseValue: 0
        XData: [1 2 3 4 5]
        YData: [8 10 7 1 9]
        

Thanks!

I think a have older version of MATLAB

for i = 1:length(hBar)
    n = length( get(hBar(i),'FaceVertexCdata') );
    set(hBar(i),'faceVertexCdata',rand(n,3))
end

Hi:

I'm sorry it still not work, the available variable relate to 'face' is: 'facecolor' and 'facealpha'.

may I know your version? I tried both 2018a and 2019a, both of them not work.

Bests,

I have v2013. Which face will change if you try this

hBar(1).FaceColor = [1 0 0];

Hi:

yes, 'faceColor' works but it is only single color. I need to change all the colors.

Thanks!
