The Error graph or series is used to represent error data. It has three mandatory
series components, Position, Mean,
and StdError. The data in the first two components specify the positions
of the series
pieces (error symbols in this case) while the data in the last component
specify the sizes of the error symbols. It also has an
optional series component called LabelMember whose data may be used as
the mark labels for the series pieces.
The ErrorStyle property determines the style in which the error
symbols are drawn.
