bar type graph/ figure

i have some values that i want to graph on a figure. This is for traffic signals.

example

%Road 1 Phase
  Green Road 1 = 50; %sec
  Yellow Road 1 = 5; %sec
  Red Road 1 = 25; %sec

    %Road 2 Phase
  Red Road 2 = 50; %sec
    Green Road 2 = 25; %sec
    Yellow Road 2 = 5; %sec

i would like to show them graphically on the same figure showing both phases in relation to each other, something like a horizontal bar chart with time along the x axis, there is nothing to plot in the y direction.

Bar 1
Green Road 1 + Yellow Road 1 + Red Road 1
Bar 2
Red Road 2 + Green Road 2 + Yellow Road 2

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

Thanks for accepting my answer if I have helped you.

You can do something like this:

     A = [50 25; 5 5 ; 25 50];
     barh(A,0.75,'grouped');
     xlabel('Seconds');
     set(gca,'yticklabel',{'Green','Yellow','Red'});

thanks, how do i plot it so it adds all the Road 1 on one bar and same for Road 2, and colour coded.

Bar 1 Green Road 1 + Yellow Road 1 + Red Road 1 Bar 2 Red Road 2 + Green Road 2 + Yellow Road 2
