I have a scatter chart using custom marker symbols. I work for a public institution, so the applications I develop need to me certain accessibility criteria. For this chart, I need a way to allow users to tab through all the scatter points. I can tab into the chart and use up/down and left/right keys, but not the tab key. I checked the API and did not see details on using the tab key to examine a series via keyboard.
Can someone please point me in the right direction?
For reference, here's an example of the chart I need to tab through: https://imgur.com/a/krYXArE
