histogram Description Creation Syntax

How I can build histogram m for numeric data that group the data into bins. After you create a Histogram object, I can modify aspects of the histogram by changing its property values?

x =ceil(10*rand(30,1));

hist(x);

a = hist(x);

% This can most likely be done without a loop, but here goes:

for ii = 1:10

text(ii,a(ii), num2str(a(ii)))

end
