please help me in plotting bar graph

 y = [327 680 509 313 ; 456 565 442 369 ; 227 325 210 3597; 426 532 360 149; 540 848 755 864];
bar_handle = bar(y,'grouped');

%When i grouped 'y' it's going from 1 to 5, but i need to it's start from 2 to 6. or it's control manually.

and please help me reshaping the array too.

 % y1(:,:,1) =  [28, 38, 25, 32, 18];
 % y1(:,:,2) =  [38, 29, 21, 42, 19];
 % y1(:,:,3) =  [31, 27, 25, 22, 25];
 % y1(:,:,4) =  [18, 32, 25, 32, 26];
 %y = [28, 38 31 18; 38, 29, 27,32;25, 21,25,25;18,19,25,26];
 %Y = [y1(column1);Y1(column2)...]

I didn't understand that part of the question. I suggest you post a new one, with a bit more detail about what are trying to do.
