When you have a stacked bar (or line) chart with lots of items, it is hard to tell which item is which. Suggestions: 1) the pop-up feature should be sorted in the same order as the stacking. 2) Maybe it would also be possible to highlight the row of stacked items if the mouse hovers over the colored circle representing the item - maybe turn the stack color black as long as the mouse hovers?
Thanks for the feedback! Will flag to the team.
