The stemseries object is the set of lines and markers that makes up

It looks like the legend is a special type of axes object with Tag set
to "legend".  Each entry in the legend is defined by three objects.
One for the line (type == "line"), one for marker (type == "line"),
and one for the label (type == "text").  The border around the legend
is part of the legend axes object itself, same as the border around a
plot axes object.  So the hard part is probably the placement, sizing,
and spacing for this object.
