% S

a1 = [2 2 3];

b1 = [2 5 6];

c1 = [0 8 9];

d1 = [2 0 12];

e1 = [2 0 12];

% H

a2 = [3 6 2];

b2 = [2 5 6];

c2 = [0 8 9];

d2 = [2 0 12];

e2 = [2 0 12];

% HS

a3 = [1 1 3];

b3 = [2 5 6];

c3 = [0 8 9];

d3 = [2 0 12];

e3 = [2 0 12];

a = [a1; a2; a3];

b = [b1; b2; b3];

c = [c1; c2; c3];

d = [d1; d2; d3];

e = [e1; e2; e3];

% T

t = [1 2 3 4 5];

dates = [a1 a2 a3; b1 b2 b3; c1 c2 c3; d1 d2 d3; e1 e2 e3];

% Plotted

figure

barh(t, d, 'hist')

If you plot this, you will notice that there are 9 bar graphs associated with each 't'. There should be only three as stated in the 'dates' variable per t. How do I stack 'a1,a2,a3, then b1,b2,b3 ...... and e1,e2,e3 each individually' to accomplish this feat?

Yes that's correct d=dates

In the above code, each of a1, a2, a3, b1,...e3 are itself vectors and not scalars. The value of the dates array is

dates =
   2     3     3     6     2     1     1     3
   5     6     2     5     6     2     5     6
   8     9     0     8     9     0     8     9
   0    12     2     0    12     2     0    12
   0    12     2     0    12     2     0    12

As you can see there are 9 columns and hence there would be 9 bars for each value in t.

Refer to Input Arguments x & y of the function barh for more information.
