How do I create a bar graph with subsections delineated?
 

I have a collection of items. Some of which are repeated. I would like to
create a simple bar graph, but one that also displays the number of times
(frequency) each item was repeated (maybe off to the side with a dash) or a
bar that totals all items (ignoring uniqueness) but colors a region to show
it was the same item repeated multiple times.

Hope this is easy to understand. Thanks!
