c = [25;55];
names = {'GR = 5.57' ; 'GR = 6.17'};
y = [604 603 ; 903 903 ; 1083 1083]';
h = bar(c,y,'FaceColor','flat');
set(gca, 'XTickLabel', names , 'TickLabelInterpreter', 'latex', 'FontSize' , 13); % , 'TickLabelInterpreter', 'latex'
ylabel({'\% contribution'},'Interpreter','latex', 'FontSize' , 14) % ,'Interpreter','latex'
xlim = get(gca,'xlim');
hold on
plot(xlim,[925 925],'LineStyle','--','Color','r','LineWidth',1.5)

In the code given above, I want to color those bars whose value is greater than 925 as red and those with less than 925 as green. I have refered to a lot of Matlab discussions regarding coloring of bar graph but nothing seems to work.

Is there a method also to have two x axis labels? Where I label each bar in a group and I label the group as well?

Thanks in advance.

The question has been resolved. The following code helps to change color of each bar in the grouped bar plot.

c = [25;55];
names = {'GR = 5.57' ; 'GR = 6.17'};
y = [604 603 ; 903 903 ; 1083 1083]';
h = bar(c,y,'FaceColor','flat');
h(1).CData(1,:) = [0 1 0]; % group 1 1st bar
h(1).CData(2,:) = [0 1 0]; % group 1 2nd bar
h(2).CData(1,:) = [0 1 0]; % group 2 1st bar
h(2).CData(2,:) = [0 1 0]; % group 2 2nd bar
h(3).CData(1,:) = [1 0 0]; % group 3 1st bar
h(3).CData(2,:) = [1 0 0]; % group 3 2nd bar

Great! Thank you so much! I've been spending more than 12 hours to figure that out.

YOu can use (bar,....','stacked')..

You need to play with inputs to get your value.

c = [25;55];
names = {'GR = 5.57' ; 'GR = 6.17'};
y = [604 603 ; 903 903 ; 1083 1083]';
h = bar(c,y,'stacked','FaceColor','flat');
set(gca, 'XTickLabel', names , 'TickLabelInterpreter', 'latex', 'FontSize' , 13); % , 'TickLabelInterpreter', 'latex'
ylabel({'\% contribution'},'Interpreter','latex', 'FontSize' , 14) % ,'Interpreter','latex'
xlim = get(gca,'xlim');
hold on
plot(xlim,[925 925],'LineStyle','--','Color','r','LineWidth',1.5)
