Accessibility is achieved in the sparkline chart control through WAI-ARIA standard. The sparkline chart features can be effectively accessed through assistive technologies such as screen readers.


WAI-ARIA (Accessibility Initiative – Accessible Rich Internet Applications) defines a way to increase the accessibility of web pages, dynamic content, and user interface components developed with AJAX, HTML, JavaScript, and related technologies. ARIA provides additional semantics to describe the role, state, and functionality of web components.

The following ARIA attributes are used in the sparkline chart:

Element Default description
Maker Reads the Location x : Location y value
Series Points Reads the Point x : Point y value
