I know he has something there on this, but I don't have time to look it up

I would like to chart three series. I would like two
columns in each group. The first column in a group would
be series 1. The second column in a group would be
series 2 and 3 stacked on each other. Is that possible?
I've come close by using secondary axis but the columns
are plotted over each other.
