Hi, Yasmin,
My understanding of your question is that you want to plot a horizontal stacked bar chart
with customized color for each bar. One way to achieve your goal is by setting 'FaceColor'
parameter for each bar using a for loop.
Here is an example, hope it is helpful.
load count.dat;
y = count(1:4,:); % y is a 4-by-3 matrix
width = 0.7;
colors = {'r', 'g', [0,0.5,0.5]}; % customized colors wrapped in a cell array, element could be either a color mark or a RGB vector
% set up colors
h = barh(y, width, 'stacked', 'LineStyle',':');
for i = 1 : 3
h(i).FaceColor = colors{i};
end
For more information, please refer to barh function document.
