— Overall performance is poor.

— The design doesn't fully comply with the guidelines.
— Dates are overlapped when scrolling the second graph.
— Filtering is slow for graphs #3 and #5.
— Total is missing for graph #3, percentage is missing for graph #5. Long tap is not implemented.
— The graphs take the entire width of the page when viewed from desktop browsers.
— Bonus goal is not implemented.

1. Interactions cannot be negative
2. If user is not on the first chart - he needs to scroll up to switch from Night to Day mode and vice versa
3. Scale and points on chart doesn't fit while moving navigation
4. Buttons' style is not done according to design
5. Animation of tooltips looks a bit delayed
6. Pointer should be displayed on navigation bar instead of default
7. Views and Messages charts should have visible grid
8. Charts do not have any visual borders (grid and navigation bar)
9. Big numbers should be abbreviated (K/M)

Animation of numbers on scale looks gorgeous; application works pretty fast in general.

No button long tap handling

The overall design wasn't changed from the 1st stage, doesn't match the 2nd stage specifications and looks untidy

Yes, there are no bonus tasks and several flaw-backs, but I very much like the animation of the disappearing lines. To my taste - this is the best deselecting line animation I've seen. At least for that the number of down-votes could have been lower.
