hello, i'm using the

barh(v,'stack')

function, where v is a matrix. the problem is that i cant figure how to make a different color for each value, for example i expect a [1,2,3;2,2,2] matrix to have 6 colors and [3,0,0;1,1,1] to have 4 colors. i tried using colormap but i didn't get 6/4 different colors. any suggestions? thanks.

Unfortunately that is not how barh works. You can find more documentation on barh usign

 doc barh
%
v=[1,2,3;2,2,2];
barh(v,'stack')

will give you two stacked bar graphs of 3 colors since there are 3 element in both of your arrays.. All barh with 'stack' does is plot a bar graph make it horizontal and stacks values on each other instead of appearing as separate bars.

I donot think colormap will help you here either..
