I am trying to implement accessibility in highcharts using version 9+.
WIth a single series, the narrator is able to read the data but in case of multiple series, unable to achieve the same.
Also, the highchart is in a IFrame.
Have a created a dummy project on JSFiddle for the same. https://jsfiddle.net/pfsbyxwz/3/
Please guide me on how to proceed.
