Create smart narrative summaries
The smart narrative visualization helps
you provide a quick text summary of visuals and reports. It provides relevant
innovative insights that you can customize.
Use smart narrative summaries in your
reports to address key takeaways, to point out trends, and to edit the language
and format for a specific audience. When you add a live Power BI report
page to PowerPoint, instead of pasting a screenshot of your report's key
takeaways, you can add narratives that update with every refresh. Your audience
can use the summaries to understand the data, get to key points faster, and
explain the data to others.
Get started
To follow along in Power BI Desktop,
download the sample online-sales scenario dataset.
To follow along in the Power BI service,
download the sample. Go to the workspace where you want to save the sample, and
select Upload. To create a smart narrative for a page or for a visual, you
need to open the sample in Edit mode.
Smart narrative for a page
On the Products page of the
report, you see it already has a smart narrative visual. You can recreate it.
Delete the smart narrative visual.
Select the report canvas, then in
the Visualizations pane, select the Smart narrative icon to
automatically generate a summary.
You see a narrative that's based on all
of the visuals on the page. For example, in the sample file, smart narratives
can automatically generate a summary of the report's visuals that address
revenue, website visits, and sales. Power BI automatically analyzes trends to
show that revenue and visits have both grown. It even calculates growth, which
in this case is 72 percent.
Smart narrative for a visual
Right-click the visual and select Summarize.
You can choose to pin the summary to the
report page.
For example, the Transactions page in
the sample file has a summary of the scatter chart that shows various
transactions. Power BI analyzes the data and shows which city or region has the
highest revenue per transaction and the highest number of transactions. The
smart narrative also shows the expected range of values for these metrics. You
see that most cities produce less than $45 per transaction and have fewer than
10 transactions.
Edit the summary
The smart narrative summary is highly
customizable. You can edit or add to the existing text by using the text box
commands. For example, you can make the text bold or change its color.
To customize the summary or add your own
insights, use dynamic values. You can map text to existing fields and
measures or use natural language to define a new measure to map to text.
For example, to add information about the number of returned items in the
sample file, add a value.
As you type a value name, you can choose
from a list of suggestions as you do in a Q&A visual. So, in addition to
asking questions of your data in a Q&A visual, you can now create your own
calculations without even using Data Analysis Expressions (DAX).
You can also format dynamic values. For
example, in the sample file, you can show values as currency, specify decimal
places, and choose a separator for thousands.
To format a dynamic value, select the
value in the summary to see your editing options on the Review tab.
Or in the text box, next to the value that you want to edit, select the edit
button.
You can also use the Review tab
to review, delete, or reuse previously defined values. Select the plus sign (+)
to insert the value into the summary. You can also show automatically generated
values by turning on the option at the bottom of the Review tab.
Sometimes a hidden-summary symbol
appears in the smart narrative. It indicates that current data and filters
produce no result for the value. A summary is empty when no insights are
available. For example, in the sample file's line chart, a summary of high and
low values might be empty when the chart's line is flat. But the summary might
appear under other conditions. Hidden-summary symbols are visible only when you
try to edit a summary.
Visual interactions
A summary is dynamic. It automatically
updates the generated text and dynamic values when you cross-filter. For
example, if you select electronics products in the sample file's donut chart,
the rest of the report is cross-filtered, and the summary is also
cross-filtered to focus on the electronics products.
In this case, the visits and revenues
have different trends, so the summary text is updated to reflect the trends.
The count-of-returns value that we added is updated to $4196. Empty summaries
can be updated when you cross-filter.
You can also do more advanced filtering.
For example, in the sample file, look at the visual of trends for multiple
products. If you're interested only in a trend for a certain quarter, then
select the relevant data points to update the summary for that trend.
There's a limit to the number of
summaries that can be generated so Smart Narratives picks the most interesting
things to summarize about the visual. Smart Narratives generates up to four
summaries per visual and up to 16 per page. The summaries that are generated
for a page depend on the location and size of visuals and it avoids generating
the same kind of summaries for different visuals. Therefore summarizing just
the visual can generate more summaries that aren't present while summarizing
the whole page.
Add a smart narrative icon to a visual
You can add an optional icon to the
header of a visual that triggers an on-demand summary of the visual contents.
Add it for accessibility purposes, to announce results to any assistive
technology. You can enable it in the Format pane for individual
visuals, or add it to your custom theme file for the visual types you choose.
Select a visual, and in the Format pane,
select General.
Expand the Header icons section,
then expand the Icons section, and set Smart narrative to On.
When your report readers hover over that
visual, they can see and select the Smart narrative icon, to expose a
text explanation of the visual. Unlike the other smart narratives, they can't
pin this narrative to the report.
Considerations and limitations
The smart narrative feature doesn't
support the following functionality:
Pinning to a dashboard
Using dynamic values and conditional
formatting (for example, data bound title)
Publish to Web
Power BI Report Server
On-premises Analysis Services
Live Connection to Azure Analysis
Services or SQL Server Analysis Services
MultiDimensional Analysis Services data
sources
Key influencers visual with a
categorical metric or unsummarized numerical field as 'Analyze' field from a
table:
that contains more than one primary key
without a primary key, and measures or
aggregates as 'Explain by' fields
Map visual with non-aggregated latitude
or longitude
Multi-row card with more than three
categorical fields
Cards with non-numeric measures
Tables, matrices, R visuals or Python
visuals, custom visuals
Summaries of visuals whose columns are
grouped by other columns and for visuals that are built on a data group
field
Cross-filtering out of a visual
Renaming dynamic values or editing automatically
generated dynamic values
Summaries of visuals that contain
on-the-fly calculations like QnA arithmetic, complex measures such as
percentage of grand total and measures from extension schemas.
