I do not think that is possible.

I have seen some crazy graphs where people will make a transparent graph and
place it on top of another graph that gives the effect of one graph.

This is a strange request.
I know how to do graphs with multiple y-axis, but I've been asked to graph 5
columns of data. The first 3 columns as a bar graph on the left y-axis and
the last 2 columns as a stacked-bar graph on the right y-axis.
Can this be done? If so, how?
Thanks for the help
