The SankeyChart is a sophisticated graphical component designed to visualize the flow and distribution of resources, energy, or data between different entities within a system. Ideal for illustrating complex relationships and transfers, the SankeyChart provides a clear and intuitive representation of proportional flows, making it easier to analyze and interpret multi-dimensional data.

Field

Description

Flow Direction

Sets the direction of the flow within the SankeyDiagram.

  1. LeftToRight: Sets the FlowDirection from Left to Right.

  2. TopToBottom: Sets the FlowDirection from Top to Bottom.

Highlight Mode

Determines the interaction mode for highlighting nodes and links.

  1. MouseLeftButtonUp: Highlighting nodes on mouse left button up.

  2. MouseEnter: Highlighting nodes on mouse enter.

First And Last Label Position

Specifies the position of the first and last labels in the diagram;

  1. Inward: Positions the labels inside the diagram area.

  2. Outward: Positions the labels outside the diagram area.

Show Labels

Determines whether labels are displayed for nodes and links.

Link Curvature

Controls the curvature of the links between nodes. A higher value results in more pronounced curves. Range of values: 0 - 1.

Node Thickness

Sets the thickness of the nodes. This value is subject to change based on panel size adjustments.

Node Gap

Defines the gap between nodes. This value is subject to change based on panel size adjustments.

Highlight Opacity

Controls the opacity level for highlighted nodes and links when HighlightBrush is not set. Range of values: 0 - 1.

Node Name

Specifies the identifier or label for a node in the Sankey diagram.

Node Color

Determines the color used to represent the node.

Link From

Defines the source node for a link in the diagram.

Link To

Defines the target node for a link in the diagram.

Link Weight

Specifies the weight or magnitude of a link, affecting its thickness. It can be defined by a fixed number or by an object.

Runtime Execution 

During runtime, the SankeyChart Control generates a Sankey diagram based on predefined engineering configurations. When the runtime environment is initiated, the SankeyChart Control applies these configurations to render the corresponding flow diagram. Users can interact with the diagram, which dynamically responds to the configured settings. This allows for consistent visualization and analysis of data flows within the application, enabling users to monitor and interpret data relationships effectively.
