Product Description:<\/b>
Highcharts is a Javascript-based charting library for software developers that helps developers create interactive and dynamic charts using web technology.<\/div>\n<\/div>\n<\/div>\n\n\n\n

Notes<\/h3>\n\n\n\n

Highcharts is a middleware software library with very high levels of customizability. The accessibility of the resulting web content is therefore the responsibility of the developer using Highcharts.<\/p>\n\n\n\n

This report outlines whether or not it is possible for developers to produce content that conforms with the guidelines by using the Highcharts Javascript software library. This is reflected in the definitions of the “Supports”,”Partially supports”, and “Does not support” terms, which have been modified from the ITI defaults.<\/p>\n\n\n\n

Highcharts includes many accessibility features not covered in this document, including support for data sonification, voice input, and dynamic data announcements to screen reader users. Read more about the accessibility features available to Highcharts developers on the Highcharts website at https:\/\/www.highcharts.com.<\/a><\/p>\n\n\n\n

Evaluation Methods Used:<\/h3>\n\n\n\n

Testing is based on general product knowledge, as well as use of contrast checking tools (WebAIM), screen readers (JAWS, VoiceOver, NVDA, Narrator), markup validity tools, low vision and color blindness simulation tools, and accessibility scan tools (Microsoft Accessibility Insights). Several browsers were used throughout the testing, including Google Chrome, Microsoft Edge, Apple Safari, and Mozilla Firefox.<\/p>\n\n\n\n

Web content created with Highcharts has also been subject to accessibility and usability user testing by accessibility specialists and people with disabilities.<\/p>\n\n\n\n
