MATLAB: How to use bar function

graphMATLABplot

Hey all,

I have X= 6 and Y= 14. I want to have a plot like this: (x is blue and y is green)

I tried so many ways, All unsuccessful and gives me various errors.

If it's a matter, this is just for January. In the next step I want to have all months in one graph.

can anybody help me?

Thank you all.

See the Display Groups of Bars example in the documentation. If you have any problems setting that up, provide your data and code and I'd be glad to set things straight.

After the bar plot is set up you can set the month names along the xticks either by using datetick() or by changing the XTick and XTickLabel properties of the axes.

MATLAB: Bar plot with error bar

Here's a demo using your data.

count = [10, 21, 32]; 
errLim = [4, 11, 19; 18, 28, 37]; 
err  = errLim - count; 
figure;
bar(count)
hold on
errorbar(1:length(count), [10, 21, 32], err(1,:), err(2,:), 'LineStyle','none')
set(gca, 'xtick', 1:length(count), 'xticklabel', {'A' 'B' 'C'})

MATLAB: Changing bar graph bar colors

By default, all the bars in a bar graph are part of the same patch object, and therefore are the same color. To get different colors, you need to plot each bar as its own object.

x = 1:4;
y = rand(1,4);
h = bar(x, diag(y), length(y));
set(h, {'facecolor'}, {'k','b','g','r'}');

h = bar(x, diag(y), 'stacked');
set(h, {'facecolor'}, {'k','b','g','r'}');
