Issue -
- tooltip gets too long when groupby has too much data points
- we need max height on tooltips
- we need to be able to scroll inside the tooltip
- not possible if the tooltip is following the cursor (which library
enforces)
- its not easy to customize Nivo's own tooltip to make it work how we
want it
what we want -
- let the tooltip anchor to the bar in such a way -- that the top of the
bar aligns with the vertical middle of the tooltip
- add max height to the tooltip
what I did -
- use floating portal from floating-ui/react
- get the hover datum (ie hovered bars) dimensions on mouse enter to
render the tooltip
- anchor the tooltip at the calculated position
- floating-ui handles the basic things like flipping/offset/shift
- clear the states as required
