I am creating a bar chart of 4 groups of data each containing 3 columns. I want to assign red for highest column and blue for smallest column in each group.

Here is my code.

exp1 = [1 2 3; 4 5 9; 8 1 6; 4 3 8];
figure()
h = bar(exp1);
set(gca,'XTickLabel',{'n-Heptane','O_2','CO','CO_2'});
for k = 1 :size(exp1,2)
    h(k).CData = k;
end

And There is a common xTicklabel for each group. How can i name each column along with common group name?

Yes, you can do it with a single bar chart. I even took the time to answer that very question on here last week, but you deleted the question before I posted my answer!
