public enum SeriesPointKey
Members
Name | Description |
---|---|
Argument
|
Specifies that sorting is performed by the argument values of a series’ data points. |
Value_1
|
Specifies that sorting is performed by the first data value within the SeriesPoint.Values array of a series’s data points. For financial data this indicates the Low value. |
Value_2
|
Specifies that sorting is performed by the second data value within the SeriesPoint.Values array of a series’s data points. For financial data this indicates the High value. |
Value_3
|
Specifies that sorting is performed by the third data value within the SeriesPoint.Values array of a series’s data points. For financial data this indicates the Open value. |
Value_4
|
Specifies that sorting is performed by the fourth data value within the SeriesPoint.Values array of a series’s data points. For financial data this indicates the Close value. |
Value_5
|
Specifies that series points are sorted based on the fifth data value within the SeriesPoint.Values array of a series’s data points. For BoxPlot series, it indicates the Max value. |
Value_6
|
Specifies that series points are sorted based on the sixth data value within the SeriesPoint.Values array of a series’s data points. For BoxPlot series, it indicates the Mean value. |

Example
The following example demonstrates how to create a ChartControl with a series of the PieSeriesView type, and add this chart to a form at runtime.
Note that this series view type is associated with the SimpleDiagram type, and you should cast your diagram object to this type, in order to access its specific options.
