Horizontal Area Graph
The Horizontal Area graph or series is functionally identical to the Area
series except that the former is drawn horizontally while the latter is drawn
vertically. It has two mandatory
series components, Position and Value.
The data in these two components specify the positions and values of the series
pieces of the series. It also has an optional series component called LabelMember
whose data may be used as the mark labels for the series pieces.
The UseOrigin property determines whether to use the Origin
property to determine the base position of the filled area. If this property is set to
false, the origin of the horizontal axis is used as the base position of
the filled area.
If multiple Horizontal Area series are drawn in the
same graph, the series that belong to the same group (those have the same value
of the StackGroup property) can be stacked together in a way specified by
