If we can assume that Foo is always a list of lists, and not a single list which
doesn't seem to be meaningful with these plots anyway, then you can use
PercentileBarChart[Sequence @@Foo];
Sequence applied to a list converts the list to a series of arguments with commas
between them which are inserted in a function. Check out Sequence in Help.
