ArcScale.MinValue Property

Gets or sets the minimum value of the circular scale.

Namespace: DevExpress.XtraGauges.Core.Model

Assembly: DevExpress.XtraGauges.v22.2.Core.dll

NuGet Package: DevExpress.Gauges.Core

Declaration

[DefaultValue(0F)]
public float MinValue { get; set; }

Property Value

Type Default Description
Single 0

A Single value that is the minimum limit of the circular scale.

Remarks

The MinValue and ArcScale.MaxValue properties together define the range of values allowed for the ArcScale. The current value indicated by the needle is specified by the ArcScale.Value property.

Note that the ArcScale.MaxValue property value needn’t necessarily be greater than the MinValue. For instance, if you switch their values, this will simply change a circular scale’s direction.

MinValue = 0, MaxValue = 100 (Default) MinValue = 100, MaxValue = 0 (Rotated)
CircularScaleValues_Default CircularScaleValues_Rotated

While the MinValue and MaxValue properties define the limit values, the number of tickmarks (and therefore labels) between them is specified by the ArcScale.MinorTickCount and ArcScale.MajorTickCount properties. The following images demonstrate how these properties can be modified together to customize the circular scale.

Default

MinValue = 0, MaxValue = 12

MinValue = 0, MaxValue = 12,

MinorTickCount = 1, MajorTickCount = 13

CircularScaleValues_Default

CircularScaleValues_MinMaxValues

CircularScaleValues_MinMaxValuesTicks

To specify the angles where the scale starts and ends, use the ArcScale.StartAngle and ArcScale.EndAngle properties.
