Accessibility

Section 508 Accessibility Compliance

The following table follows The Voluntary Product Accessibility Template® to provide information how amCharts software complies with the accessibility requirements of Section 508 of the Rehabilitation Act.

Criteria Supporting Features
(a) A text equivalent for every non-text element shall be provided (e.g., via “alt”, “longdesc”, or in element content). Fully supported

amCharts adds an aria-label and aria-description for every relevant element of the chart (columns, bullets, map areas, etc.), which is a standard way for screen readers to narrate non-textual information.

Accessible label content is automatically populated by default. It can also be tweaked by programmers using configuration options.

(b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. Not applicable

amCharts libraries do not display any multimedia presentations and therefore do not require alternative presentations.

(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. Fully supported

amCharts provides theme functionality as well as some high-contrast themes. amCharts also provides means replace colors with other means of visual identification, such as patterned fills, configurable dotted and dashed lines, variable fill opacity, etc.

It’s up to the implementer of the library to select the level of reliance on colors.

(d) Documents shall be organized so they are readable without requiring an associated style sheet. Not applicable

amCharts libraries do not rely on style sheets.

(e) Redundant text links shall be provided for each active region of a server-side image map. Not applicable

amCharts libraries do not use server-side image maps.

(f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape. Not applicable

amCharts libraries do not use client-side image maps.

(g) Row and column headers shall be identified for data tables. Not applicable

amCharts libraries do not use data tables.

(h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers. Not applicable

amCharts libraries do not use data tables.

(i) Frames shall be titled with text that facilitates frame identification and navigation  Not applicable

amCharts libraries do not use frames.

(j) Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. Not applicable

amCharts provides various animations in their products. However, in such, we rely on browser-rendering of the animation and in such are not in any direct control on the refresh times.

In any case, no amCharts product has any functionality that could make the whole screen flicker.

(k) A text-only page, with equivalent information or functionality, shall be provided to make a web site comply with the provisions of this part, when compliance cannot be accomplished in any other way. The content of the text-only page shall be updated whenever the primary page changes. Not applicable

amCharts provides visual and interactive data visualization libraries. The resulting on-screen controls are designed to be fully accessible.

It’s up to implementer of the charts to consider if separate text-only page is required to complement the interactive control.

(l) When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by Assistive Technology. Fully supported

Most of the uniquely-identifiable elements – bullets, areas, controls, legends, etc. – as well as controls – grips, buttons, scrollbars – will automatically have an aria-label attached which will include all of the information in text format, such as values, names, positions, ranges, etc.

It can further be customized by the implementer of the library.

(m) When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with §1194.21(a) through (l). Not applicable

amCharts libraries do not rely on applets, plug-ins, applications or any other external resource.

(n) When electronic forms are designed to be completed on-line, the form shall allow people using Assistive Technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. Not applicable

amCharts libraries do not require users to fill out electronic forms.

(o) A method shall be provided that permits users to skip repetitive navigation links. Fully supported

amCharts provides means of applying different tabIndex for each group of elements. This allows the implementer of the charts to define groups of elements, which in turn enables screen reader applications to employ their own means of “jumping to next group”.

Furthermore, amCharts intuitively sets which element of the chart should be selectable, and which should not. It can further be configured by implementer of the charts.

(p) When a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required. Not applicable

There are no time-limited functionality in amCharts products.
