Graphsheet box plots grouping

[Thom Burnett <Thom.Burnett@cognigencorp.com>]

How do I group box plots within a panel?

I have a handful of panels based on a z-variable - say 'Id'
and I want to box plot 'age' and 'weight' for each of these people with 
the plots for each person next to each other - ideally each person gets 
their own panel.
I don't want to have to create extra columns or other dataset changes if 
it can be avoided.
The Windows 7.0 gui seems to say it can be done, but I haven't been able 
to. I can overlay the two box plots in each panel but can't get them to 
go side by side.
Any help would be appreciated.
