Arria NLG for Power BI: Release Notes

Documentation for Arria NLG’s Add-in for Power BI Desktop


17 February 2020

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


Enhancements and New Features

Parameter Control Feature. Parameter Control provides a new way for users to dynamically configure narratives from within 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.

Up to three parameters can be created in the new Parameter Control feature, and Studio projects can be configured to use them in a multitude of ways. See the documentation on how to use the new Parameter Control feature with JSON-type and table-type projects.


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.


Bug Fixes

Table-type data set downloads issue. An issue limiting the size of tabular data sets 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.




This release was based on version 2.0.0 of Arria’s add-in for Power BI (December 2019). Features and bug fixes are detailed below.


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();

See the documentation for the full list of supported functions. [Documentation coming soon.]

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.


Bug Fixes

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.
