Changing color of individual bars in a grouped bar chart

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)

Sir, I want the bar plots individually. In the plot attached below, I want those bars with value lesser than 925 colored in green and those with value greater than 925 colored in red. Each bar represents a seperate configuration for me. Using stacked plot defeats the purpose.

i got your question....you have to change your input accordingly...

[Deepak Prakash K]

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