While mouse hover on left axis/bottom axis , can we change tooltip text?
Bottom axis have tooltip option?
Currently, from what I can see with similar tickets submitted in the past, there’s no mechanism that allows you to change the axis tooltip text or to disable it outright - bottom axis tooltips will only just give you back the hovered-over axis label verbatim, at this time.
I have converted the ticket you submitted otherwise for this into a feature request - issue 89848.
