Gets or sets a value that specifies the scale type of series points’ values.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v24.1.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public ScaleType ValueScaleType { get; set; }

VB.NET

Public Property ValueScaleType As ScaleType

Property Value

Type	Description
ScaleType	A ScaleType enumeration value, which specifies the values type.

Available values:

Name	Description
Qualitative	Identifies the Qualitative data scale. This means that data provided for the Series.Points will be treated as qualitative values, and will be shown on the axis as textual representations (e.g., A, B, and C).
Numerical	Identifies the Numerical data scale. This means that data provided for the Series.Points will be treated as numerical values, and will be shown on the axis as numbers (e.g., 100, 200, and 300). Use the AxisBase.Label‘s AxisLabel.TextPattern property to define the output format of numerical values shown on the axis.
DateTime	Identifies the DateTime data scale. The data that you provide for the Series.Points will be treated as DateTime values, and will be shown on the axis as DateTime values (e.g., January, 2003, January, 2004, and January, 2005). The axis’s DateTimeScaleOptions property allows you to specify the scale-related settings. To define the output format of DateTime values shown on the axis, use the AxisBase.Label‘s AxisLabel.TextPattern property.
TimeSpan	Identifies the TimeSpan data scale. The data that you provide for the Series.Points will be treated and shown on the axis as TimeSpan values (for example, 00:00:00, 00:00:01, 00:00:02). Note that in this case, the axis’s TimeSpanScaleOptions property allows you to specify the scale-related settings. To define the output format of TimeSpan values shown on the axis, use the AxisBase.Label‘s AxisLabel.TextPattern property.
Auto	A scale type is detected automatically based on the type of underlying data. This means that numerical data will be treated as numerical, date-time data as date-time, qualitative as qualitative values. Note that this mode can be applied only for the Series.ArgumentScaleType property.
