Why can't I click the box corresponding to a single ftrace event?

hello~
Why can't I click the box corresponding to a single ftrace event to view specific information?
And select a range to view all ftrace event information within the range.

thanks very much.

Hi! These features are simply not implemented yet. They're on our roadmap, but I'm afraid I don't have a time scale I can share with you just yet.
