Hi All,

We are working on some charts that displays the values upon mouse
hover on the line chart. Kindly let me know your thoughts on making
this functionality for keyboard users.

Ajay,
without knowing anything about your charts, one idea is to allow the entire chart to be focusable as a single Tab stop (this means it would need an accessible name of some sort), then allow Arrow keys to move focus around the data points. Another Tab would move keyboard focus out of the chart. A Shift-Tab would move focus out of the chart backwards.

This might not be a great idea if the chart has like a gazillion data points.

Visible clear instructions for this keyboard setup is necessary. Can't expect people to know how this might work.

cheers,
Mallory
