Section 508
The Chart is compliant with the Section 508 requirements. For more information, refer to the article on Accessibility Compliance Table in Telerik UI for ASP.NET Core.
WCAG 2.2
The Chart supports the standards for providing accessible web content which are set by the Web Content Accessibility Guidelines 2.1.
Meeting some of the Success Criteria in WCAG 2.2 may require additional customization:
-
**1.4.3* Contrast (Minimum)*
The color of chart elements may need to be customized to meet the minimum required contrast level. Some Theme Swatches like the Ocean Blue A11y Accessibility Swatch meet and exceed this criteria.
-
**2.5.8:* Target Size (Minimum)*
The size of Series Markers and the font size of Legend Items may need to be customized to meet the minimum size of 24x24px required by this criteria.
