Build Data Views for Accessibility

If you want to make your views accessible to as many people as possible, or if you work in an environment that is subject to US Section 508 requirements, other accessibility-related laws and regulations, you can use Tableau to build data views that conform to the Web Content Accessibility guidelines (WCAG 2.0 AA). This includes building views that are accessible to users who use screen readers, braille keyboards, keyboard-only navigation, and so on.

View controls that support accessibility

To create an accessible view, use Tableau Desktop to create a view that includes WCAG-conformant elements, and then publish and embed that view in a web page that conforms to Web Content Accessibility guidelines (WCAG 2.0 AA).

The example below shows a view with a scatter plot chart and includes various elements that you can use to be WCAG conformant. For more details, see Best Practices for Designing Accessible Views and Author Views for Accessibility.

Note: The color blind palette can help you select colors that can be recognized by users with visual impairments. When you assign colors to different dimension values make sure that they provide enough contrast and aren't too close to each other on the light-dark spectrum.

Additional support for accessible views

In addition to the controls shown in the illustration, Tableau also supports the following features to help you create accessible views:

  • Keyboard navigation

  • Programmatic context for assistive technologies (using ARIA roles)

  • A text equivalent for charts and visualizations

  • Compliance with contrast standards

  • Authentication when signing in to Tableau Server for embedded views

Note: If you use a data source that requires authentication to access it, that authentication page does not conform to the WCAG 2.0 AA guidelines. To prevent the authentication page from showing, you can embed the credentials for the data source when you publish. For information about how to embed credentials for the data source, see Set Credentials for Accessing Your Published Data, "Set the authentication type", Embedded password section.
