Remarks

Use the SankeyDiagramControl.NodeLabel property to access node label settings. The following options allow you to configure text for node labels:

• TextOrientation - Label text orientation.
• MaxWidth - Label width in pixels.
• MaxLineCount - The number of lines that multiline text can occupy.
• TextAlignment - Text alignment.
• Font - Font parameters.

C#

sankeyDiagramControl1.NodeLabel.TextOrientation = TextOrientation.TopToBottom;
sankeyDiagramControl1.NodeLabel.MaxWidth = 200;
sankeyDiagramControl1.NodeLabel.MaxLineCount = 1;
sankeyDiagramControl1.NodeLabel.TextAlignment = StringAlignment.Center;
sankeyDiagramControl1.NodeLabel.Font = new Font(FontFamily.GenericSerif, 10);

VB.NET

sankeyDiagramControl1.NodeLabel.TextOrientation = TextOrientation.TopToBottom
sankeyDiagramControl1.NodeLabel.MaxWidth = 200
sankeyDiagramControl1.NodeLabel.MaxLineCount = 1
sankeyDiagramControl1.NodeLabel.TextAlignment = StringAlignment.Center
sankeyDiagramControl1.NodeLabel.Font = New Font(FontFamily.GenericSerif, 10)

You can also handle the CustomizeNode event to access a specific node and customize it based on a certain condition:

C#

sankeyDiagramControl1.CustomizeNode += OnCustomizeNode;
//...
private void OnCustomizeNode(object sender, CustomizeSankeyNodeEventArgs e) {
    if (e.Label.Text == "France" && e.Node.Level == 0) {
        e.Label.Font = new Font("Tahoma", 16);
        e.Label.Text = "France (Source)";
    }
}

VB.NET

Private Sub OnCustomizeNode(ByVal sender As Object, ByVal e As CustomizeSankeyNodeEventArgs)
    If e.Label.Text Is "France" AndAlso e.Node.Level = 0 Then
        e.Label.Font = New Font("Tahoma", 16)
        e.Label.Text = "France (Source)"
    End If
End Sub
