Range.MinValue Property

Gets or sets the minimum value to display on an Axis. This may not be the same as the minimum value of the series associated with this axis.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v19.1.dll

Declaration

C#

[XtraSerializableProperty(XtraSerializationVisibility.Hidden)]
public object MinValue { get; set; }

VB.NET

<XtraSerializableProperty(XtraSerializationVisibility.Hidden)>
Public Property MinValue As Object

Property Value

Type	Description
Object	A Object that specifies the minimum value to display on an axis.

Remarks

Use the MinValue property to specify or obtain the minimum value to display on an axis.

Note that the MinValue and Range.Auto properties are interdependent: changing one property will reset the other.

Note

Dealing with Qualitative or DateTime scale types, it may be required to determine the minimum value more precisely than allowed by these scale types. For example, for an axis whose DateTimeScaleOptions.MeasureUnit property is set to Year, it may be required to restrict its range by Month. To do this, you can use the Range.MinValueInternal property, which stores the internal, numeric representation of Qualitative and DateTime values.

For more information, refer to Visual Ranges and Whole Ranges .
