stacked bar graph from 3 columns

I have this table T

T
X        Y            Z
1         0            5 
1         1            3 
1         2            3 
2         0            6
2         1            0 
2         2            7      

how do I get a bar plot of Y stacked (X) vs Z (on the y axis) .

So it will be Y vs Z but Y will have two colors one for 1 and nother for 2.

Not at all clear what you really intend here, sorry...can you sketch what you think result should be and attach the image?

For 'stacked' the columns are sum of rows; there are as many bars as rows.

So, if your data array above is XYZ, then

Z=reshape(XYZ(:,3),3,[]);
bar(XYZ(1:3,2),Z,'stacked')

creates the orientation to produce what you've sketched.
