Incorrect values:
iPhone XS, iOS 12.1
There are no animation of date labels on x axis.
Incorrect tooltip view for the last chart (w/o percentage column)
Chart 3 (stacked bars): no selected value in main area, no 'All' values in popup
No dots (a.k.a. circles) when focusing on line charts.

Overall not a bad work even without bonus tasks, definitely it doesn't deserve so many dislikes.
Chrome 73.
Right handle "jumps" when resizing using left handle, and probably other way around also. Expectation: should remain stationery.
Long touch / long click functionality is not realized
Chrome 73
When displaying tooltip for stacked bar charts the vertical line does not have a width of a bar and the non-focused bars are not masked.
Chrome 73
When navigating to the end of available dates, it is impossible to focus on correct date at the end - the dates seem to be trimmed by several days.
Chrome 73
1. The right edge of the percentage chart trembles on scroll.
2. The tooltip can't be closed.
