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

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)

Can you please elaborate on your comment? What do you mean change the input accordingly? What input are you refering to?
