Is it necessary to use Overlay (if you need coloring, color supports multiple columns but I would most likely just rely on X-axis having both categories visible)
Graph Builder(
Size(1024, 632),
Show Control Panel(0),
Include Missing Categories(1),
Variables(X(:Make), X(:Doors, Position(1)), X(:Make), X(:Year, Position(2)), Y(:Wt), Color(:Doors), Color(:Year)),
Elements(Position(1, 1), Box Plot(X(1), X(2), Y, Color(1), Legend(8))),
Elements(Position(2, 1), Box Plot(X(1), X(2), Y, Color(2), Legend(3))),
Local Data Filter(Add Filter(columns(:Count_Make), Where(:Count_Make >= 25.81))),
SendToReport(
Dispatch({}, "Make", ScaleBox, {Label Row(1, Show Major Labels(0)), Label Row(2, Show Major Grid(1))}),
Dispatch({}, "Make", ScaleBox(2), {Label Row(1, Show Major Labels(0)), Label Row(2, Show Major Grid(1))})
)
)
or without color
