It sounds like what you want to do is return the counts and bin centers from hist(). In other words, do not plot with hist(), rather user bar() to plot. The third input argument to bar() is the bar width.
[N,X] = hist(randn(1000,1));
bar(X,N,0.5)
% the input 0.5 controls the bar width, it defaults to 0.8

I have a question on the answer. i don't think we can set the width if we use the option in bar graph to use 'histc'. i want to end up in a histogram grouped together, with white background and a width of 0.3 but i can get them all at a time. Although this worked, but cannot adjust the width of the bar columns.
if true
% code
hist(WS,bins,'w');
h = findobj(gca, 'Type', 'patch');
set(h, 'FaceColor', 'w');
end

If by histogram width, you mean the width of the bins, then you can do that by specifying the number of bins you use as an input argument; this is documented.
Or use histc() and specify the edges as a vector input.

You can simply modify the width of the plot
hist(randn(1000,1))
ax = gca;
get(ax,'position')
Now you'll see a vector with 4 elements. The 4 elements are
[left bottom width height]
so add to the width value. You'll probably want to reduce the left value as well to keep the histogram "centered"
