Synthetic dimension functions
A synthetic dimension is created in the document from values generated from the synthetic dimension functions and not directly from fields in the data model. When values generated by a synthetic dimension function are used in a chart as a calculated dimension, this creates a synthetic dimension. Synthetic dimensions allow you to create, for example, charts with dimensions with values arising from your data, that is, dynamic dimensions.
Note: Synthetic dimensions are not affected by selections.
The following synthetic dimension functions can be used in charts.
