Multiple histogram with different colors for each bar

Hi to everybody,

I plotted an histogram of different set of data in different columns with the command bar:

bar((linspace(1,nx,nx))',matY');

where nx is the number of column of matY. Furthermore, the histogram for every point in x has m different columns as the number of rows of matY. The resultant plot is:

Now, I would like to change the colors of the columns, so every type of rho has the color that I want. How can I do?

Thank you

Use the output handles to the bar objects.

h = bar(1:nx,matY');
h(1).FaceColor = [0 0 0];   %first bar group
h(2).FaceColor = 'g';       %second bar group
% Etc...

Or set all colors at once.

c = [1     0     0  %one [r,g,b] color vector per bar group
     0     1     0
     0     0     1
     1     1     0
     0     1     1];
 set(h, {'FaceColor'}, mat2cell(c,ones(size(c,1),1),3))
