stacked combo charts

[#1]

Hi!

How can I do a stacked combo chart with two dimensions and two expressions?... When I add the second expression, the stacked option is greyed out... is it not possible?

When I get the same problem,

I use OverLapping Charts One above the Other.

Alexandra,
A combo chart with two dimensions and two expressions is always stacked, so the option is greyed out.
