From @Nuria :
- Overlay with point values keeps on displaying even when cursor is no longer on top of graph. It should disappear. F17054773
- Unify the aspect of popups for all chart types: map, line, bars
- Bar chart popup does not work visually for very short bars, is lost in the white of teh background, and the arrow is not visible.
- Line chart popup blocks visibility of lines: we should make line chart popup dynamic
