Creating your Data Connection in Astrato
-
In Astrato, connect to your live data source.
-
From the lobby sidebar, click Data.
-
Click (+) New connection and select the cloud data source type. The steps for each source type are slightly different, with options for user/password or enterprise SSO. Please see the article in Astrato on setting up data connections. We recommend using Snowflake with Vizlib Live!
Note: The schema, view and field name can also be identified when creating the embed link in Astrato. Apply a filter before creating an embed link, and the name of the schema, view and field name will be included in the URL when including the filter in the embed link.
Viewing your Data Model Details in Astrato
Now that you’ve connected your data, the data model details as they display in Astrato will need to be added in Vizlib Live!
You can copy and paste them from Astrato into the fields in Vizlib Live! to ensure that the field names match, including any spaces.
-
Data View/ Table name
-
Schema name
-
Field name
Note: The content in these fields must be the same - the fields are case-sensitive, and they must match any spaces in the names.

Creating and Publishing your Workbook in Astrato

-
Create your workbook. There's also a tutorial for learning Astrato in our VizLab. We hope you'll enjoy creating your workbook while exploring how working with live data could benefit your business.
-
Publish your workbook to a collection. You'll select the embedded object, groups, or sheets from your published workbook to link to in Vizlib Live!
-
Use the Embed process to generate the link to view and interact with your data story in Qlik Sense. You can select a single data object, a group, or the whole sheet to share in Qlik Sense. Click the option to Copy Link to just use the URL.

Viewing your Embedded Astrato Visualization
When a field is connected in the extension, it appears in the lower-left corner, indicating the field from Qlik Sense that has been connected through the extension (1).
Figure 5: Shows the field connection (1), the cloud icon to disconnect the data connection (2), and the icon to refresh your data (3).
Refreshing the Data Displayed
Click the refresh button in the lower right corner (3).
Disabling the Data Connection
To disable the Live connection in the extension, click on the cloud in the lower right corner of the extension (2). This may be useful if you want to restrict the consumption of data from your data cloud or, if you are going to add many selections/filters; as this stops visualisation from loading/recalculating with each filter applied.
