ScrollingRange.MinValue Property

OBSOLETE

This property is obsolete now. Use AxisBase.WholeRange.MinValue instead.

Gets or sets the minimum value to display on an Axis, when the diagram is scrolled.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v18.2.dll

Declaration

[Obsolete("This property is obsolete now. Use AxisBase.WholeRange.MinValue instead.")]
[Browsable(false)]
[TypeConverter(typeof(AxisRangeMinValueTypeConverter))]
[XtraSerializableProperty(XtraSerializationVisibility.Hidden)]
public object MinValue { get; set; }

Property Value

Type Description
Object

A Object that specifies the minimum value to display on an axis, when the diagram is scrolled.

Remarks

Use the MinValue property to specify or obtain the minimum value to display on an axis, when the diagram is scrolled.

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

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 AxisBase.DateTimeMeasureUnit property is set to Year, it may be required to restrict its scrolling range by a Month. For this, you can use the ScrollingRange.MinValueInternal property, which stores the internal, numeric representation of Qualitative and DateTime values.

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

Example

This example demonstrates how to use the AxisBase.VisualRange property to define the visible range of an axis, and the AxisBase.WholeRange property to define its whole range.
