DxSankey.SortOrder Property

Specifies the sort order of Sankey nodes in corresponding columns.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public Dictionary<string, int> SortOrder { get; set; }

Property Value

Type	Description
Dictionary<String, Int32>	A collection of nodes and their weights.

Remarks

The Sankey component arranges nodes in columns based on node weights: the heavier the weight, the lower the node appears in the corresponding column. The default weight of all Sankey nodes is 1 – the component displays nodes in the order they are declared in the data source.

The Sankey component allows you to change the default node arrangement: assign a collection of nodes and their new weights to the SortOrder property.
