XYDiagramPaneBase.EnableAxisYScrolling Property
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v18.2.dll
Declaration
[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
[XtraSerializableProperty]
public DefaultBoolean EnableAxisYScrolling { get; set; }Property Value
| Type | Description |
|---|---|
| DefaultBoolean | A DefaultBoolean value, which represents the availability of Y-axis scrolling. |
Available values:
| Name | Description |
|---|---|
| True | Corresponds to a Boolean value of true. |
| False | Corresponds to a Boolean value of false. |
| Default | The value is determined by the current object’s parent object setting (e.g., a control setting). |
Remarks
Use the EnableAxisYScrolling property to specify whether it’s allowed to scroll an individual pane along its Y-axis.
Important
The EnableAxisYScrolling property affects on the pane’s scrolling capability only on the WinForms platform. The ASP.NET WebForms Chart Control and MVC Chart Extension do not support this feature.
When the EnableAxisYScrolling property is set to Default, the actual scrolling status is determined by the XYDiagram2D.EnableAxisYScrolling property value.
At runtime, you can get the actual status of a pane’s Y-axis scrolling, via the read-only XYDiagramPaneBase.ActualEnableAxisYScrolling property.
For more information, refer to Zooming and Scrolling (2D XY-Charts).
Example
This example demonstrates how you can individually adjust scrolling along the required axes. A chart with two panes is used to demonstrate this feature.
In this example, a chart with two series is created. The second series is assigned to an additional pane.
In addition, to show scrolling bars along axes, the axis whole range and axis visible range is specified and the ScrollingOptions2D.UseScrollBars property is set to true. To learn more on axis ranges, refer to Visual Ranges and Whole Ranges .
To specify scrolling along the axes of the diagram’s panes, the XYDiagram2D.EnableAxisXScrolling and XYDiagram2D.EnableAxisYScrolling properties are used.
For more information, refer to Zooming and Scrolling (2D XY-Charts).
