Change the color of each bar in the Bar graph of 3 arrays

Hi,

I am getting a bar graph like this with one color.

I need same color for the first element of each array.. My code is like this

encomb=[4 3 2 1;5 4 3 2; 6 5 4 3 ];

figure(12)

hold on

bb=bar(encomb(:))

xlabel('type of consumer')

ylabel('energy consumed kWh/month')

title('Energy consumed for different case studies')

hold off

Try this, but with your own colors in clr:

clr = rand(12,3);
encomb=[4 3 2 1;5 4 3 2; 6 5 4 3 ];
figure(12)
hold on
bb=bar(encomb(:), 'facecolor', 'flat');
bb.CData = clr;
xlabel('type of consumer')
ylabel('energy consumed kWh/month')
title('Energy consumed for different case studies')
hold off

Output:

Hi,

Thank you.

Sorry I didnt mention in the question.

I need same color for the first element of each array.

Perhaps I misunderstood your original question. The issue maybe that you "ungrouped" the data by passing encomb(:) into the bar function. If you pass in encomb instead, the data are treated as groups, one group per row. You'll get different colors for each bar within a group, but the same color for bar positions between groups:

encomb=[4 3 2 1;5 4 3 2; 6 5 4 3 ];
figure(12)
hold on
bb=bar(encomb, 'facecolor', 'flat'); % NOTE: encomb, not encomb(:)
xlabel('type of consumer')
ylabel('energy consumed kWh/month')
title('Energy consumed for different case studies')
hold off

Here, you are getting MATLAB's default colors for a bar chart with grouped data. Is this what you want?
