DxChart<T>.SetValueAxisVisualRange(List<Object>, String) Method

Applies a specific visual range to a value axis.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

public void SetValueAxisVisualRange(
    List<object> range,
    string axisName = null
)

Parameters

Name	Type	Description
range	List<Object>	The value range.

Optional Parameters

Name	Type	Default	Description
axisName	String	null	The value axis name

Remarks

The Chart component may include multiple value axes. To apply a visual range to a specific axis, set its name in markup and pass it to the SetValueAxisVisualRange method as a parameter.

If you do not pass the axis name, the Chart applies the specified visual range as follows:

Single-pane charts

To the first value axis in chart markup.

Multi-pane charts

To the value axis that belongs to the default pane.

Note

We do not recommend that you call the SetValueAxisVisualRange method in single-pane charts with multiple axes. Once you call the method, the Chart tries to adjust visual ranges for all value axes and may render series incorrectly.

You can also apply a specific visual range to the argument axis using the SetArgumentAxisVisualRange method. To reset visual ranges for all axes, call the ResetVisualRange() method.

To respond to visual range changes, handle the Chart’s VisualRangeChanged event.

Example

The following code snippet displays a custom Set Visual Range button that applies a specific visual range to the Temperature value axis:
