The result is a carefully crafted experience for people who benefit from increased legibility, Accessible Rich Internet Applications (ARIA) markup, and keyboard navigation. The new site enabled us to prevent accessibility issues from the beginning, and a new codebase made it possible for us to integrate new accessibility tools and features that would have been difficult or impossible to build and maintain on the old site.īy taking advantage of the latest advancements in React, we have been able to introduce new accessibility tools, techniques, and technology. This complexity made it difficult to incorporate sweeping changes without causing regressions. The previous site had been built upon in layers since its launch in 2004, resulting in a large and complex site. When that project began, we saw an opportunity to integrate greater accessibility into the site and build it into the foundation in a way we couldn’t have done without this rebuild. MORE INFO For more info on how data binding work, check out this article.We recently shared the work we did to rebuild our tech stack to support the redesigned. We can do that by setting title's readerTitle: title.readerTitle = "An interactive chart prepared from finance department" title.readerTitle = "An interactive chart prepared from finance department" ).

Which one will be read out, and in what order depends on actual user's settings and the reader software he or she uses.Īs an example, let's revisit the chart title example we had at the beginning of this chapter. The former is set via element's readerTitle property. There are two pieces of textual information that element can have: a title and a description. This is why we have a separate section in this article, dedicated to series.Įvery single element on a chart can have some text for screen readers.

The screen reader information is conveyed via "ARIA" labels, like aria-title, aria-labelledby, and aria-describedby.įor example, the whole chart will indicate it's type.Ī series will indicate what type of series it is.Įach individual item in series, like column, will indicate its X and Y value, or if it's a Slice in PieSeries, it's category, value and percent.Īctually, there's a bit of fuzzy logic involved in screen readers and series. They are chosen to be as relative and descriptive as possible. Most of the elements in amCharts 4 come with pre-defined screen reader prompts. Screen reader text Default screen reader prompts SIDE READING If you'd like to change how focused items look, read " Changing appearance of focused items".

In a nutshell, if an item is "focusable" it can be TAB'ed into or selected with a mouse.

Others can be enabled by setting their focusable property.įor example, if we want to make a specific chart title (more about chart titles later in this article) focusable, we do this: let title = () Most of the elements that we think should be focusable are already pre-set so by default. Other examples of focusable items: togglable legend item, scrollbar grip, zoom out button.Įxamples of irrelevant elements: axis labels, grid lines. User needs to be able to TAB through focusable items, so that screen reader can read relevant information. We call those "focusable" items.įor example, a column in a ColumnSeries is important. Some of those are more relevant for vision-impaired users than the others.

Common principles Focusable itemsĪ chart is full of elements: buttons, lines, columns, labels, and million of other items. Make sure you use it, or better yet, the latest version available at the time. The latest accessibility-related bugs were fixed in version 4.6.9.

Some functionality described in this article may not work on older versions of amCharts 4 due to bugs related to accessibility features. This article aims at outlining built-in accessibility features, configuration opportunities, and adherence to standards. Result is a charting library that is usable with screen readers and other perception enhancement tools out-of-the box, yet super flexible to modify the behavior to suit particular needs. In amCharts 4, accessibility is not an afterthought, but rather something that was included in the planning from day zero.
