For further information or help with any of these issues, please contact our Support Team.

Version 2.2.0

February 2020

This release is based on version 2.1.0 of Arria’s add-in for Power BI.

1. Enhancements and new features

  • Parameter Controls

    The Parameter Controls feature provides a new way for users to dynamically configure narratives from within the Arria add-in for Power BI.

    By adding these controls to your dashboard, you make it possible for users to explore different scenarios by specifying the parameters of the business rules that drive their narrative. For example, they can create a threshold control that filters out a subset of your data for analysis, and a second control that affects the granularity of the narrative describing that data subset.

    See the documentation on how to use the new Parameter Control feature with JSON-type and table-type projects.

  • Support for Power BI bookmarks feature

    The Arria custom visual now supports Power BI bookmarks. Using Power BI bookmarks with Arria’s add-in enables you to make more efficient use of the limited real estate on your report page. Harness NLG Studio’s power to aggregate and narrate your entire dataset by embedding multiple narratives on each page without compromising on the number of visuals: if it’s in your dataset, you can bring a discussion of it into your report:



  • User Interface enhancements

    The version number and a link to Arria’s Support portal have been added to the add-in’s user interface.


2. Fixed issues

  • Table-type data set downloads issue

    An issue limiting the size of tabular datasets that could be successfully downloaded to a .csv file from the Arria add-in has been fixed. Previously, downloading large data sets would result in an empty .csv file.


Version 2.1.0

This release is based on version 2.0 of Arria’s Power BI add-in from December 2019.

1. Enhancements and new features

  • Auto-increment field

    In table-type (Describe a Table) projects, the auto-increment field is now optional. Opting out allows users to keep their own identity column.

  • Enhanced mapping-script function library 

    For example, to add an entry into the metadata object in the JSON, you can use the following:

    var data=getData();
  • Insight detection

    Insight detection. In the out-of-the-box narrative configuration, under Descriptive Statistics, the Use selected attribute order option is now enabled. This allows use of a new insight-detection strategy. (Choose the Let us decide option if you prefer to use the default detection strategy.)

  • Summaries

    In this release, for out-of-the-box narratives, you can now generate summaries in addition to Important things and Tell me everything. To generate summaries, in the Tell me how to say it section, choose the Summary option.

  • Ability to disable add-in configuration

    In this release, the add-in configuration is disabled for users who don’t have edit permissions in the Power BI service or in Power BI Report Server.


2. Fixed issues

  • Support for Internet Explorer 11 (IE 11)

    Now you can view dashboards with the Arria add-in using IE 11. Note: The copy/paste feature that works in Chrome, Edge, and Firefox does not work in IE 11.

  • HTML links in the narrative view are now navigable

    Users can now click links embedded in the narrative to navigate outside of Power BI.

  • Improved out-of-the-box narratives

    Minor bugs relating to narrative generation have been fixed.
