Hi there!
I am trying to update a webpage to make a chart accessible. The chart has a
lot of data, so describing it all in alt text isn't feasible. So, I would
like to create an accessible table for screen readers so that visually
impaired users can access the date displayed in the chart.
Alas, I'm not a programmer/developer; I have minimal javaScript (but my
markup and CSS is pretty good!). So I've been plucking code from the Google
Charts samples and fiddling. I have created the chart I want, and I have
also added a table pulling from the same data:
chart.draw(data, options);
table.draw(data, {showRowNumber:false});
The table shows up, and I can always position it off-screen. However,
The October 6, 2014 release notes say:
- Accessibility
- Adding table with data for screen readers.
- Fix for text with auras.
- More accessibility fixes/tweaks.
So I wanted to see if there's any more information on that. Is drawing a
table from the same data the way to go, or is there some specific function
for creating an accessible table that screen readers will access when
encountering the chart?
(Apologies for being such a novice. Any guidance would help!)
Thanks,
Adam
