Adjusting automatic refresh

Cloudera Data Visualization offers an automatic refresh feature that refreshes all visuals on the dashboard simultaneously, regardless of the type of visual used (for example: charts, external links, tables). This is especially helpful for dashboards that contain dynamic data, such as stock tickers or real-time event updates.

To enable automatic refresh for your entire dashboard, navigate to the General menu and adjust the value in the selector for the Auto-refresh seconds option.
This sets the refresh rate in seconds for the entire dashboard.

This example demonstrates how to create a simple dashboard with a refresh rate through using an external link visual to access live information about the 2017 French Presidential election.

While this example uses a link visual, the automatic refresh setting affects the entire dashboard, meaning all visuals will refresh based on the set interval.

  1. Start a new dashboard based on any dataset.
  2. In the Visual Designer, click New Visual.
  3. Hover over the Visual Controls in the top right corner of the new visual and click the (pencil) icon to edit the visual.
  4. Select External Link from the Visual Type Catalog.
  5. In the URL field, enter https://en.wikipedia.org/wiki/French_presidential_election,_2017.
  6. Name and save the new visual.

    In this example, the name of the visual is French Election 2017.

  7. In the dashboard Settings, set the Auto-refresh seconds option to 300 seconds, which is equivalent to an update every 5 minutes.
  8. Name the new dashboard.

    In this example, the name of the dashboard is News.

  9. Click Save.
  10. Click ViewSwitch to View mode to observe the periodic updates of the dashboard.
