The High-Low graph or series is used to represent data as a set of vertical lines. It
has three mandatory series components,
High, and Low. The data in the first component specify the
horizontal positions of the vertical lines while the data in the last two
components specify the vertical positions of the two endpoints of the vertical
lines. It also has an optional series component called LabelMember
whose data may be used as the mark labels for the lines.
The endpoints representing the data in the High or Low components
can be optionally connected with a line whose appearance is controlled by the HighPen
or the LowPen property.
The area between two adjacent vertical lines may be optionally filled. The appearance of each filled area is determined by either the HighBrush
or the LowBrush
property, depending on whether the corresponding value in the High
component is larger than the value in the Low
