I now have Excel 2007 and what used to be easy is not so in many cases. One
of these cases is the creation of a combo chart - a set of 3 columns that are
represented by bars and 1 column represented by a line with a seperate axis.
I know I've done it before, I think they were even 3D bars, but now when I
try to change the series it changes the whole chart. HELP!
