ManualNumericScaleOptions.GridSpacing Property

Gets or sets the numeric grid step in grid alignment units.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v23.1.dll

NuGet Package: DevExpress.Wpf.Charts


public double GridSpacing { get; set; }

Property Value

Type Description

A Double value which specifies the numeric grid step.


This feature manages label placement along the axis.

By default, the GridSpacing is set to the default value, so the grid step is calculated automatically. To change the grid step interval for axis labeling, set the ManualNumericScaleOptions.AutoGrid to false, and specify the GridSpacing property value.

The table below shows the GridSpacing property in action for random data.

ManualNumericScaleOptions.GridSpacing = 1 ManualNumericScaleOptions.GridSpacing = 2
ManualNumeric_GridSpacing_1 ManualNumeric_GridSpacing_2


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

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

To use the automatic numeric scale options, set the AxisX2D.NumericScaleOptions property to AutomaticNumericScaleOptions and choose the appropriate AutomaticNumericScaleOptions.AggregateFunction.

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