How does one plot a histogram from the histogram counts?

I have produced an array of counts, specifically produced with:
histcounts
the reason I do this is because storing the actual data is way to expensive in terms of storage. So on the fly I update my histcount. Now that I have them, how do I plot the histogram?
----
demo code:
W_hist_counts = zeros(1,D);
for i=2:iter+1
W = get_vector_we_want_stats(W)
%
W_hist_counts = W_hist_counts + histcounts(W,nbins);
end
----

I assume you want to normalize to an overall sum of 1. You should just be able to plot
W_hist_counts/sum(W_hist_counts)
to normalize, right?

histogram() can plot the histogram data (counts vs values) if you pass in the counts and values instead of the data. Otherwise you can do it manually with bar().
