Stacked Bar graph with two horizontal axis??

I have a Gantt graph I am making for a project. I am happy with it for the most part

It is a stacked graph obviously with a moving dateline and it all works great!

( The moving date line is not accurate as I am using bunk dates for testing, otherwise it DOES move correctly)

On the very top of the graph is a bar for Total project completion. The bar is simply showing a percentage. The percentage is an average of the tasks percentages on the Data tab.

Right not I have that bar as an embedded graph on top of the main graph and it looks good........on screen.


When I print it doesn't show that embedded graph of course.

What I am wondering is how can I get that one bar to have completely different axis and data then the rest of the graph??

I haven't found way to have dual axis on a stacked bar graph.
