horizontal bar graphs/ figures

how do i plot specific colours with a barh graph. i can plot specific colours for the first stacked bar graph but not for the second as h =barh... only produces 'h' values for the first stacked bar graph. Any help would be appreciated. Thx

MJ_Green= 50;              
MJ_Yellow= 5;                                
MJ_Red=25;     
MN_Yellow =5;                         
MN_Green=25;  
MN_Red=50; 
Red_time_both= 2;    
%
Phasing_ALL = [MJ_Green, MJ_Yellow, MJ_Red, Red_time_both ; MN_Red, MN_Green, MN_Yellow, Red_time_both];
h = barh(Phasing_ALL,0.5,'stacked');
xlabel('Seconds','FontSize',12);
set(gca,'yticklabel',{'Major Road','Minor Road'});
set(h(1),'Facecolor','g');
set(h(2),'Facecolor','y');
set(h(3),'Facecolor','r');
set(h(4),'Facecolor','m');

need to set colours for second bar also.

You have to realize that in a stacked bar plot you really have 2 bar plot objects, not 3 like you seem to think. You can modify the two 'Facecolors', the first group of bars and the second group

    A = [50 25; 5 5 ; 25 50];
     h = barh(A,0.75,'stacked');
     xlabel('Seconds');
     set(gca,'yticklabel',{'Green','Yellow','Red'});
     set(h(1),'Facecolor','yellow');
     set(h(2),'Facecolor','red');

Or pass a vector

   A = [50 25; 5 5 ; 25 50];
       h = barh(A,0.75,'stacked');
       xlabel('Seconds');
       set(gca,'yticklabel',{'Green','Yellow','Red'});
       set(h(1),'Facecolor',[0.5 0.5 0.5]);
       set(h(2),'Facecolor',[1 1 1]);
