Bar graph and "stacked" options.

I would like to obtain a bar graph with olnly some data showed as stacked.

For example consider this script.

A=[1 2 3; 2 5 3; 1 4 3];
bar (A)

I can obtain a also this type of graph with 'stacked' bars

bar(A,'stacked')

I would like to obtain a graph in wich only some data are stacked.

For example the first elements of A should appear "1" as alone bar and "2 ,3" stacked with different coulors. how can i do it?

I tryed this but it dosent work.

bar(A(1,1), A(1,2:3),'stacked')

This is solved easily by adding zeros in the columns that you do not want a stack, e.g.

bar ( [1 2 3;0 2 3;0 0 6]','stacked')

Thaks but this is not the result i am looking for.

I would like to obtain a graph with 3 group of columns eah group made by 2 clolumns,

the first group is made by: bar1=A(1,1), bar2= A(1,2)+A(1,3) and so on

the second bar3=A(2,1), bar4=A(2,2)+ A(2,3)

the third bar4=A(3,1), bar5=A(3,2)+ A(3,3)
