1. Syntax


2. Input

The Rank Value function requires the following input:

  • d0 – The set of data values for which the Rank Value is calculated.

3. Parameters

The Rank Value function requires the following parameters:

  • s0 – The rank position in the list of values.
  • s1 – The sorting type. 0 ranks from the highest value to the lowest, while 1 ranks from the lowest to the highest.
  • s2 – Whether duplicate values are considered as multiple values in the ranking. The default value is false.
  • Alignments... (One or More, Optional) – Hierarchy placeholders to be used as the alignment axis. Input values are grouped by the specified hierarchy values before ranking them: e.g., RANKVAL($Quantity$, 2, null, null, $Country$) calculates the 2nd highest quantity for each country.

When using alignment parameters in a formula visualization, you can choose to display these values grouped by only the alignment hierarchy values, for example to display just the N-ranked value for each country without the original input values.

4. Output

The Rank Value function generates a single value from the data set that corresponds to the indicated rank (or for each group when using alignment parameters).
