LinearScale.Value Property

Gets or sets the scale's current value.

Namespace:DevExpress.XtraGauges.Core.Model
Assembly:DevExpress.XtraGauges.v17.1.Core.dll

Expanded Syntax

Property value

Type: Single
The scale's current value.
The default is 0.

Expanded Remarks

A scale's minimum and maximum values are specified by the MinValue and MaxValue properties, respectively. Typically, you set the scale's Value in this range. However, you can set the value beyond this range, and then correct the range to have it include the specified Value.

When you assign a value to the Value property, the value is stored in an internal variable (let's call it internalValue). Reading the Value property returns the following values:

  • internalValue, if it falls in the range [MinValue; MaxValue];
  • MinValue, if internalValue is less than MinValue;
  • MaxValue, if internalValue is greater than MaxValue;

Only the value returned by the Value property is persisted. This means that the internalValue is not persisted, if it falls outside the range [MinValue; MaxValue].

To get the internalValue, use the GetInternalValue method.

The current value is displayed by the level bar represented by the DevExpress.XtraGauges.Win.Gauges.Linear.LinearScaleLevelComponent class. To display the value, ensure that a level bar exists, and it's linked with the scale via its LinearScale property. If no level bar is associated with the scale, the current value will not be indicated.
