The dashboards editor provides a graphical canvas for a line-of-business user to begin investigating data for patterns and insights. You don't need to understand coding or SQL to explore the data and gain insights. Alternatively, you can hand off the dashboard to a data scientist for deeper analysis and predictive modeling.

  4. Create visualizations of your source data by using the following options in the left-hand pane of the dashboard:
    • Sources: Enables selecting a data source connection. The data source must exist and have been added as a data asset on the Assets page of the project, see also Known issues for data sources. The following data sources are supported:
    • Visualizations: Opens many different types of graphs that you can use to visualize the data from the selected data source connection. Drill down into your source connection and select the data segments you want to visualize.

Actions on dashboards

All dashboards are listed in the Dashboards section on your project's Assets page.

When you open a dashboard, you are notified if an associated data asset, for example a CSV file or a connection, is missing from your dashboard. You can select to skip the data asset or to relink it. Before you can relink the asset, you must add the missing asset to your project. Data assets associated with a dashboard might be missing if the data asset was removed from your project, or when you download a dashboard and create a new dashboard from the downloaded dashboard JSON file in a different project without the data assets it uses. If you do not relink the missing asset to the dashboard, the dashboard graphs will not render.

You can select the following actions from the Actions menu of a selected dashboard:
