Accessibility
RadChart has been replaced by RadHtmlChart, Telerik's client-side charting component. If you are considering RadChart for new development, examine the RadHtmlChart documentation and online demos first to see if it will fit your development needs. If you are already using RadChart in your projects, you can migrate to RadHtmlChart by following these articles: Migrating Series, Migrating Axes, Migrating Date Axes, Migrating Databinding, Features parity. Support for RadChart is discontinued as of Q3 2014, but the control will remain in the assembly so it can still be used. We encourage you to use RadHtmlChart for new development.
Compliance Level
Telerik RadChart is Level AAA content compliant (in conformance with the W3C Web Accessibility Guidelines 1.0).
Telerik RadChart satisfies the requirements of "Section 508" for software accessibility. As a result, the component can be used in US Federal Institutions and other organizations requiring software to be accessible to people with disabilities.

Section 508
The USA federal mandate requires that information technology be made accessible to people with disabilities. Much of Section 508 compliance concerns making Web sites, intranet, and web-enabled applications accessible. Section 508 compliance has since become a major prerequisite not only in government related software, but also in most enterprise and corporate software solutions.
W3C Web Content Accessibility Guidelines 1.0
The main goal of these guidelines is to encourage developers in creating applications providing accessible contents. However, adhering to these guidelines will also make Web content more accessible to all kind of users, using different devices and interfaces: desktop browser, voice browser, mobile phone, automobile-based personal computer, etc.
In accordance with these guidelines W3C defines three levels of conformance developers may implement in order to provide some level of content compliance to their products:
• Conformance Level "A"• Conformance Level "Double-A"• Conformance Level "Triple-A"
For more details on W3C "Web Content Accessibility Guidelines 1.0" see https://www.w3.org/TR/WAI-WEBCONTENT/
In our attempt to make our products content compliant, each web-control we develop and its QSF strive to obtain at least one of conformance levels listed above.
