	Sankey chart visualizes for examples volumes of related items between two or more set of features. It's also suitable for showing flow of material or information from place to other. In the sankey, there are two or more vertical pillars, containing the values of the features. There are flows drawn between the feature values where the width of the flow represents the weight of the feature combination.

			* '''End level''': Defines which level the flow ends to. If not defined, all flows end to the next level from the start.

			when defining the start level, you can create sankey charts where there are more than two levels. When defining the end level, you can create sankey charts where flows jump over levels.

	Sorting can be used to set the vertical order of start and end items in the left and right pillars of the sankey. If sorting by the dimension mapped as start or end, the order is set alphabetically by the start or end items. If sorting by the weight, the highest or lowest weight flows are on top.

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.
