Dimensionality() returns the number of dimensions for the current row. In the case of pivot tables, the function returns the total number of dimension columns that have non-aggregation content, that is, do not contain partial sums or collapsed aggregates.
Syntax:
Dimensionality ( )
Return data type: integer
Limitations:
This function is only available in charts. The number of dimensions in all rows, except the total which will be 0, will be returned. For all chart types, except pivot table it will return the number of dimensions in all rows except the total, which will be 0.
Sorting on y-values in charts or sorting by expression columns in tables is not allowed when this chart function is used in any of the chart's expressions. These sort alternatives are therefore automatically disabled. When you use this chart function in a visualization or table, the sorting of the visualization will revert back to the sorted input to this function.
Examples:
A typical use for dimensionality is when you want to make a calculation only if there is a value present for a dimension.
| Example | Result |

For a table containing the dimension UnitSales, you might only want to indicate an invoice is sent: IF(Dimensionality()=3, "Invoiced"). |
