Hi, attached a qvw, i hope can help you.
In the first graphic "Industry" is used as dimension only, select a "Campaign" in the list box and filter wath you want to see.
In the second graphic "Industry" and "Campaign" are used as dimension. In the inner circle appear Campaign.
Maybe need modify colors to make ir more clear.
Sorry for my bad english.
