Accessibility is achieved in the smith chart control through WAI-ARIA standard. The smith 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 smith chart:

Element Default description
Title Reads the smith chart's title
Legend Reads the series name
Maker Reads the Location x : Location y value
Series Points Reads the Point x : Point y value
