I've been thinking more about the legend.

I'm thinking that it is like an axis or group and could be removed except 
for the fact that it has the linked objects.  Perhaps we could introduct 
an "Inherits" property for lines, patches, etc that would let all 
properties that are not specified be read from another object?  It could 
be a little tricky, but I think it could work and it could remove the need 
for a legend.

How does that sound?
