Error Bar Graph
The Error Bar 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 while the data in the last component specify the sizes of the series
pieces. It also has an
optional series component called LabelMember whose data may be used as
the mark labels for the series pieces.
The Error Bar series is very similar to the Error
series. The main
difference between the Error Bar series and the Error series is that a bar is
drawn in addition to the error symbol in each series piece to represent the corresponding value in the Mean
The ErrorStyle property determines the style in which the error
symbols are drawn. The BarStyle property determines the style in
which the bars are drawn.
The UseOrigin property determines whether to use the Origin
property to determine the base position of the bars. If this property is set to
false, the origin of the vertical axis is used as the base position of the bars.
