I have 3 columns of data: (1) product name; (2) date of production; and
(3) quantity produced. The data is arranged in rows. In other words,
each row corresponds to a particular product. Also note that not all
production dates are unique.

I would like to create a bar chart with one bar for each product. The
date of production should be on the x-axis, quantity produced on the
y-axis, and the product names as the legend text. But I can't quite seem
to get it right. I've got 23 nicely colored bars and the product names
as the legend text. But I can't get the dates on the x-axis.

It seems like I might need to somehow fool Excel into doing what I want.
But I don't know how to get it done. Any help you can provide would be
much appreciated.

Thanks,
Rich
