Hi
I'm trying to plot bar with errorbars on the same figure. I tryed to use barweb (<http://www.mathworks.com/matlabcentral/fileexchange/10803-barweb-bargraph-with-error-bars>) but it doesn't seem to work. Is there an inbuilt function in Matlab?
The data I'm working with is similar to this:
mean_velocity = [0.2574, 0.1225, 0.1787]; % mean velocity
std_velocity = [0.3314, 0.2278, 0.2836]; % standard deviation of velocity

There is not a built-in for this, but you can superpose an errorbar() chart with a bar chart:
mean_velocity = [0.2574, 0.1225, 0.1787]; % mean velocity
std_velocity = [0.3314, 0.2278, 0.2836]; % standard deviation of velocity
figure
hold on
bar(1:3,mean_velocity)
errorbar(1:3,mean_velocity,std_velocity,'.')
I feel that this may not be exactly what you want, but it should give you an idea of what is possible

figure
hold on
bar(1:9,mean_velocity1)
errorbar(1:9,mean_velocity1,std_velocity1,'.')
figure
hold on
group = [mean_velocity1 mean_velocity2];
bar(1:9,mean_velocity2)
errorbar(1:9,mean_velocity2,std_velocity2,'.')
figure
hold on
gives me separate graphs. How shall I compare them in 1 plot with different colors?

@chaitra You are creating a new figure for the second plot --> comment the fifth line of your code.

Hi Based on the previous answer, I figured this script out:
young= [458.05,509.63]; %values are for young and old respectively
young2= [458.05,509.63,200,340];
old= [200,340];
group = [young;old];
SEM=[12,12,56,45]; % values for error bars
figure
hold on
bar(1:2,group)
errorbar([0.86,1.14,1.86,2.14],young2,SEM,'.') %errorbar(x,y,err)

How to change colors ?([0.86,1.14,1.86,2.14], what is the use of this?
