AxisBase.VisualRange Property

Gets the settings that specify the visible range of the axis coordinates.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v19.1.dll

[XtraSerializableProperty(XtraSerializationVisibility.Content)]
[NonTestableProperty]
public VisualRange VisualRange { get; }

<NonTestableProperty>
Public ReadOnly Property VisualRange As VisualRange

Property Value

Type	Description
VisualRange	A VisualRange object which contains the common visual range settings of the axis coordinates.

Remarks

The VisualRange property is used in descendants of the AxisBase class. The primary settings exposed via the properties of the Range class allow you to specify the minimum and maximum axis values (see the Range.MinValue and Range.MaxValue properties), or control whether they should be calculated automatically based upon the series being drawn (see the Range.Auto property).

For more information, refer to Visual Ranges and Whole Ranges and Zooming and Scrolling (2D XY-Charts).

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.

For more information on axis range, refer to Visual Ranges and Whole Ranges .
