On a related note, our app has a lot of charts. What are the best practices for making time-series graphs accessible? I'd imagine just listing the values wouldn't be particularly helpful for graphs with hundreds or more points - and being able to programmatically summarize the interesting takeaways from an arbitrary chart would probably be useful for our sighted customers as well.

- Angostura 7y agoJust pondering whether there is a system that converts line graphs into series of rising and falling tones, while a voice reads out the x axis markers. If you have multiple series, you could have different sounds running in parallel - sin wave, square wave or perhaps musical instruments each denoting a different series. That might actually be usable if there was an automated system for creating them on the fly. There's also this kind of approach https://www.youtube.com/watch?v=I9lquok4Pdk https://www.youtube.com/watch?v=I9lquok4Pdk

- dbjorge 7y agoHighcharts has put a lot of effort into designing charts to be accessible. They did a presentation about it at my workplace a few months ago and I was impressed by the passion and level of user testing they had done. https://www.highcharts.com/docs/accessibility/accessibility-module https://www.highcharts.com/docs/accessibility/accessibility-... is a good starting point to learn more about the sorts of features and considerations they've made (you can find articles, demos, and videos describing more from there)
