Sankey charts

Binder  Notebook

Summary: This example shows how to create sankey charts in F#.

Sankey charts are a visualization of multiple, linked graphs layed out linearly. These are usually used to depict flow between nodes or stations. To create Sankey, a set of nodes and links between them are required. These are created using the provided Node and Link structures.

open Plotly.NET

let sankey1 =
    Chart.Sankey(
        nodeLabels = [ "A1"; "A2"; "B1"; "B2"; "C1"; "C2"; "D1" ],
        linkedNodeIds =
            [ // Edgelist, toupling sourceIndex => targetIndex of the link
              0, 2
              0, 3
              1, 3
              2, 4
              3, 4
              3, 5
              4, 6
              5, 6 ],
        NodeOutlineColor = Color.fromKeyword Black,
        NodeOutlineWidth = 1.,
        linkValues = [ 8; 4; 2; 7; 3; 2; 5; 2 ],
        LinkColor =
            Color.fromColors
                [ Color.fromHex "#828BFB"
                  Color.fromHex "#828BFB"
                  Color.fromHex "#F27762"
                  Color.fromHex "#33D6AB"
                  Color.fromHex "#BC82FB"
                  Color.fromHex "#BC82FB"
                  Color.fromHex "#FFB47B"
                  Color.fromHex "#47DCF5" ],
        LinkOutlineColor = Color.fromKeyword Black,
        LinkOutlineWidth = 1.,
        UseDefaults = false
    )

Node alignment

The NodeAlign parameter controls how nodes are aligned horizontally. The available options are Left, Right, Center, and Justify (the default).

Use the NodeAlign parameter on Chart.Sankey to apply alignment via the convenience overload, or pass Align to SankeyNodes.init directly when building nodes manually:

let sankeyAligned =
    Chart.Sankey(
        nodeLabels = [ "Source A"; "Source B"; "Sink" ],
        linkedNodeIds = [ 0, 2; 1, 2 ],
        linkValues = [ 8; 4 ],
        NodeAlign = StyleParam.SankeyNodeAlign.Left,
        UseDefaults = false
    )

<summary> The central type that gets created by all Chart constructors is GenericChart, which itself represents either a single chart or a multi chart (as a Discriminate Union type). A GenericChart consists of four top level objects: Trace (multiple of those in the case of a MultiChart), Layout, Config, and DisplayOptions. - `Trace` is in principle the representation of a dataset on a chart, including for example the data itself, color and shape of the visualization, etc. - `Layout` is everything of the chart that is not dataset specific - e.g. the shape and style of axes, the chart title, etc. - `Config` is an object that configures high level properties of the chart like making all chart elements editable or the tool bar on top - `DisplayOptions` is an object that contains meta information about how the html document that contains the chart. </summary>
