Occurs after automatic layout settings are applied to the X-axis’ labels.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v23.1.UI.dll

NuGet Package: DevExpress.Win.Charts


public event CustomizeXAxisLabelsEventHandler PivotChartingCustomizeXAxisLabels

Event Data

The PivotChartingCustomizeXAxisLabels event's data class is CustomizeXAxisLabelsEventArgs. The following properties provide information specific to this event:

Property Description
Axis Gets the X-axis, whose labels are being customized.
Staggered Specifies whether the X-axis labels should be staggered.


When a familiar data source (such as the PivotGridControl) is assigned to the chart’s ChartControl.DataSource property, and the ChartControl.AutoLayoutSettingsEnabled property is turned on, the AxisLabel.Staggered property is defined automatically, and cannot be customized at design time.

Handle the PivotChartingCustomizeXAxisLabels event to manually adjust this option (via the CustomizeXAxisLabelsEventArgs.Staggered property). To access the X-axis, use the CustomizeXAxisLabelsEventArgs.Axis property.


The X-axis’ labels are staggered if the axis scale type is Qualitative or DateTime (except for Year). And, the labels’ direction is made parallel to that of the axis (e.g., the AxisLabel.Angle is 0 if the diagram is not rotated, and the AxisLabel.Angle is 90 when the diagram is rotated). In addition, the labels’ text is affected by the measurement unit specified (e.g., Year, Month, or Day), and the superfluous labels are made hidden.
