ManualDateTimeScaleOptions.GridOffset Property

Gets or sets the offset of grid lines.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v21.2.dll

Declaration

public double GridOffset { get; set; }

Property Value

Type Description
Double

A Double value which specifies the grid offset.

Remarks

By default, the ManualDateTimeScaleOptions.AutoGrid is true, and the GridOffset is set automatically. If you wish to change the grid offset, specify the GridOffset property value.

Example

This example demonstrates how to use the manual date-time scale options of the X-axis.

Data aggregation is enabled automatically for the date-time scale on the X-axis in both automatic and manual scale options.

When the AxisX2D.DateTimeScaleOptions property is set to ManualDateTimeScaleOptions, you can define the ManualDateTimeScaleOptions.GridAlignment, ManualDateTimeScaleOptions.MeasureUnit and ManualDateTimeScaleOptions.AggregateFunction properties manually.

To use the automatic date-time scale options, set the AxisX2D.DateTimeScaleOptions property to AutomaticDateTimeScaleOptions, and select the appropriate AutomaticDateTimeScaleOptions.AggregateFunction.

To prevent the axis scale from being divided into intervals (and thus prevent chart data from being aggregated), set the ManualDateTimeScaleOptions.AggregateFunction property to None.
