Occurs after a chart has been bound to a Pivot Grid.
Namespace: DevExpress.XtraCharts.Web
Assembly: DevExpress.XtraCharts.v24.1.Web.dll
NuGet Package: DevExpress.Web.Visualization
Declaration
Event Data
The PivotGridSeriesPointsExcluded event's data class is PivotGridSeriesPointsExcludedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| ActualSeriesPointCount | Specifies the actual number of points in a series of a Chart that is associated with a Pivot Grid. |
| AvailableSeriesPointCount | Specifies the available number of points in a series of a Chart that is associated with a Pivot Grid. |
| Series | Gets an auto-created series, for obtaining both its actual and total number of points. |
Remarks
When an ASPxPivotGrid is assigned to the chart’s ASPxDataWebControlBase.DataSourceID property, the maximum number of points allowed for an auto-created series is limited by the PivotGridDataSourceOptions.MaxAllowedPointCountInSeries property value.
Note
A zero value for this property specifies that the number of points is not restricted.
Handle the PivotGridSeriesPointsExcluded event, to obtain both the current and total number of points (via the PivotGridSeriesPointsExcludedEventArgs.ActualSeriesPointCount and PivotGridSeriesPointsExcludedEventArgs.AvailableSeriesPointCount properties), e.g. to notify a user that the number of points has been forcibly limited. An auto-created series can be accessed via the PivotGridSeriesPointsExcludedEventArgs.Series property.
To limit the number of series in a chart, use the similar PivotGridDataSourceOptions.MaxAllowedSeriesCount property and the corresponding WebChartControl.PivotGridSeriesExcluded event handler.
