AutomaticNumericScaleOptions Class

Contains settings for a numeric axis data when its scale mode is automatic.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v19.2.dll

Declaration

public class AutomaticNumericScaleOptions :
    NumericAggregationScaleOptionsBase
Public Class AutomaticNumericScaleOptions
    Inherits NumericAggregationScaleOptionsBase

Remarks

An object of the AutomaticNumericScaleOptions type is returned by the AxisX2D.NumericScaleOptions, AxisX3D.NumericScaleOptions, and CircularAxisX2D.NumericScaleOptions properties.

In the Automatic scale mode, the Chart control automatically defines the most optimal unit of measure for an axis based on the input data, the current chart control size and the zoom level.

Data for each interval on the X-axis is aggregated using the function specified by the AutomaticNumericScaleOptions.AggregateFunction property. Although by default, aggregate function is set to Average, it can be changed to Minimum, Maximum, Sum, etc.

To learn more, see Data Aggregation.

Examples

This code snippet shows how to access the automatic numeric scale options for the X-axis scale and specify the aggregate function. The automatic options allow the chart control to automatically define the optimal unit of measure for an axis based on the input data, and the zoom level.
