Errorbars on bar-graph

Question

I\'m trying to get: a nice bar graph of groups. I\'d like error bars on each bar like this (or similar at your discretion):

Answer 1

It's really not that crazy!

You can just use errorbar with the data that you have readily available.

This code computes the correct locations, by adding 1 for every group and 1/7 for each bar within a group.

for i = 1:5
    j = 1:6; 
    x = -0.5 + i + 1/7 * j; 
    errorbar(x, ff(j,i), ee(j,i), '.'); 
end

Results in:

(Leaving out the labels, but otherwise this seems pretty similar to what you were looking for)

Answer 2

the centre of each bar can be obtained by

x = get(get(h(i),'children'),'xdata');
barsx=mean(x,1);

barsx gives the center for every ith element of every bar subset.

h=bar(bars)
for i=1:6
  x = get(get(h(i),'children'),'xdata');
  barsx(1:6,i)=mean(x,1)
end
hold all
h=errorbar(barsx,bars,barsvar)

to have the errors having the same colors as bar:

figure()
h=bar(bars) 
col=[0 0 1;0 1 0;1 1 0; 1 1 1; 0 0 0; 0 1 1];
colormap([0 0 1;0 1 0;1 1 0; 1 1 1; 0 0 0; 0 1 1])
hold all
for i=1:6
  x = get(get(h(i),'children'),'xdata')
  barsx=mean(x,1)
  h1=errorbar(barsx',bars(1:6,i),barsvar(1:6,i),'color',col(i,:))
  set(h1,'linestyle','none')
end
