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

@Allison

"pause" is required but not because it gives matlab some time to draw, but because, internally, "pause" calls "drawnow". just drawnow should work too

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)
