How do I combine a bar chart with summary data (for example, 5 categories of
summary data) with a stacked bar chart (a sixth category made up of the parts
that make the summary)?

For example, I have 6 construction projects. I wish to show summary data for
five of the projects (assume they are complete) as a bar chart. I have 4
categories of subtotals that make up each summary. In the case of the sixth
project, wish to show these sub totals as a stacked bar. I want to do this on
one chart.
