Declaration

    SankeyColorizerBase,
    IPaletteProvider,
    ISankeyPaletteRepositoryProvider

               ISankeyPaletteRepositoryProvider

Remarks

The Sankey diagram control uses the SankeyPaletteColorizer to color nodes. A new color from the palette is applied to each node with a unique label. Colors repeat if the number of unique labels exceeds the number of palette colors. To apply a gradient fill to links, the control utilizes the source and target node colors.

Specify the Palette property to change colors that are used to paint a Sankey diagram. You can select one of the predefined palettes.

To paint links with the same color, use the LinkColor property.

The code below specifies a diagram’s palette and link color:

C#

sankeyDiagramControl1.Colorizer = new SankeyPaletteColorizer {
    Palette = Palettes.NorthernLights,
    LinkColor = Color.Gray
};

VB.NET

sankeyDiagramControl1.Colorizer = New SankeyPaletteColorizer With {
            .Palette = Palettes.NorthernLights,
            .LinkColor = Color.Gray
        }

You can also create a new palette as follows:

C#

using System.Drawing;
//...
    Palette palette = new Palette("Custom") {
        Color.Red,
        Color.Green,
        Color.Blue
    };
    sankeyDiagramControl1.Colorizer = new SankeyPaletteColorizer { Palette = palette };

VB.NET

Imports System.Drawing
'...
    Dim palette As Palette = New Palette("Custom") From {
        Color.Red,
        Color.Green,
        Color.Blue
    }
    sankeyDiagramControl1.Colorizer = New SankeyPaletteColorizer With {
        palette
    }
