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 series points are sorted based on the first data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_1 indicates the Low value. For BoxPlot series, it indicates the Min value.

Value_2

Specifies that series points are sorted based on the second data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_2 indicates the High value. For BoxPlot series, it indicates the Quartile1 value.

Value_3

Specifies that series points are sorted based on the third data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_3 indicates the Open value. For BoxPlot series, it indicates the Median value.

Value_4

Specifies that series points are sorted based on the fourth data value within the SeriesPoint.Values array of a series’s data points. For financial data, Value_4 indicates the Close value. For BoxPlot series, it indicates the Quartile3 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 shows how to create a Pie chart at runtime.

View Example

Pie Chart

The Chart Control uses the Simple Diagram to display pies. Cast the ChartControl.Diagram property to the SimpleDiagram type to access diagram settings. The Chart Control determines the diagram type based on the series that is added first. We recommend that you access the diagram to configure its settings after at least one series is added to the chart.

To access pie series view settings, cast the SeriesBase.View property to the PieSeriesView type.
