boxplot occurences distribution plot

I have a matrix of occurences (7 rows(countries),46 columns(number of shoes)), n – number of occurences – for example in "a" I have n1=450, single pair of shoes…
   1   2   3  .... 46
a n1  n2   n3 .... n46
b
.
. . g
I would like to produce 7 boxplots representing the distribution in each category a-g. Normally I would have 450 times 1, n2 times 2 etc… is there a simple way to do it? Does anybody have a suggestion for a nicer representation than the boxplot?
Thank you

This may partially answer what you want. Step 1 would be to take the data for "a" and stretch it out as you describe. Here's one way to expand a data vector according to a vector of frequencies:
f = [4 3 0 1 2];    % frequencies
d = [1 2 3 4 5];    % data
c = [0, cumsum(f)]; % cumulative sum of frequencies
x = zeros(1,c(end));
for j=1:length(c)-1
   x(c(j)+1:c(j+1)) = d(j); % insert each value as required
end
