Ranking Analysis

About the narrative

Details covered in the analysis

The narrative includes:

  • an overview section that summarizes ranking changes in a measure (Profit) for the highest priority dimension (Country). For example:

    pbi-ranking-analysis-overview.png
  • subsections that describe top and bottom ranking changes and when they happened, for up to three dimension drilldowns. For example:

    pbi-ranking-analysis-drilldown-3.png

The narrative wording depends on the selected aggregation types, referring, for example, to total, average, minimum or maximum values. For the Percentage, Rating and Ratio entity types, total values are omitted from the narrative as it does not make sense to sum up non-additive measures.

The app attempts to describe as much detail as possible, but when there is too much to describe the narrative will not report on dimensions below the second dimension drilldown.

Tip

Set the order of dimension drilldown in Step 2 of the NLG Apps wizard.

See Narrative options for further guidance on configuring the narrative.
