Doesn't work at all

- extra day displayed, also day formatting above big graph is not as expected (15)
- unchecked values are discplayed on chart 3 (16)
- last day is not displayed (17)
- small chart on graph 5 is not as expected (18)
- have freezes while hovering over / dragging big graphs wich 6x CPU slowdown (i7 7700)

1) Hotizontal scrolling gets aborted once I leave my cursor out of the scroll area
2) It was possible and better to place more date labels inside X axis (screen below)

1) The horizontal rules are unexpectedly static, only the axis values are animated. 2) The zooming window design does not follow the reference images, neither checkboxes do.

1. All the lines expect one get disabled when I touch a button during a scrolling.
2. Lines disappear after quick buttons clicking.
3. The bar charts have an undesired grey overlay when a mouse cursor is over.
4. The bar charts must start from 0, not from the lowest value.

When trying to zoom in the single column chart, there is some error that stops the new graphs to appear, but the new buttons are added and the timeline (navigator) is hidden.

Wrong type of timeline (navigator) for the pie chart.

Pie chart tooltips don't display values, but percents instead

No pie chart separation on hover / touch / click

But absolutely no reason to put so many dislikes to this work. The author implemented all bonus tasks and tried to follow the guidelines - probably just didn't have enough time. No dislike from me.

— Overall performance is below average.
— Design does not comply with the guidelines. 
— The app is slow when scaling and scrolling the graphs.
— Sloppy on filtering graphs #3 and #5.
— The boxes reflect filtered data.
— Bonus goal is completed, however parts of expected animations are missing.
