Sankey Chart

Sankey chart visualizes volumes between values of two features. It is also suitable for visualizing flow from a feature to another. To use sankey, following mappings need to be defined

• Start: The feature on the left side of the sankey. Usually this is textual data, but any data types can be used here.
• End: The feature on the right side of the sankey. Usually this is textual data, but any data types can be used here.
• Weight: The weight determines the thickness of the flow drawn between the left and right value in the sankey.

By default the first dimension is the start mapping, the second dimension is the end mapping and the first measure is the weight. If you need to change the mappings, they can be found in the measure, dimension or column settings dialog.

Creating filters is also possible when clicking the flows in the sankey. The created filter is based on the dimensions/columns that are mapped as start and end. Note that creating filters is not always possible, as there needs to be a meaningful filter rule available that represents the dimension/column.
