AggregateFunction Enum

Lists the values that specify the aggregate function used for an axis.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v18.1.dll

Declaration

C#

[ResourceFinder(typeof(XtraChartsResFinder), "PropertyNamesRes")]
[TypeConverter(typeof(EnumTypeConverter))]
public enum AggregateFunction

VB.NET

<TypeConverter(GetType(EnumTypeConverter))>
<ResourceFinder(GetType(XtraChartsResFinder), "PropertyNamesRes")>
Public Enum AggregateFunction

Members

Name	Description
None	The aggregate function is not applied.
Average	Aggregates data by calculating the average value for a selected numeric or date-time interval.
Sum	Aggregates data by calculating the summary for a selected numeric or date-time interval.
Minimum	Aggregates data by calculating the minimum value for a selected numeric or date-time interval.
Maximum	Aggregates data by calculating the maximum value for a selected numeric or date-time interval.
Count	Aggregates data by calculating the number of non-null values for a selected numeric or date-time interval.
Financial	Aggregates financial data for a selected interval into a single high-low-open-close data point, so that the high value equals the highest value of all data points in this interval; the low value equals the lowest value of all data points; the open value equals the open value of the first data point and the close value equals the close value of the last data point.
Custom	Aggregates data using the custom CustomAggregateFunction calculator.
