Overall average performance.

— Slightly sloppy on vertical scrolling and graphs scaling.
— Parts of expected animations are missing.
— A long tap on a data filter is partially implemented.
— Inaccurate points positions on the graphs.
— Bonus task isn't implemented.
Long tap doesn't work when other filters are applied (graphs #3 and #5).

Thank you all for the feedback!

Please explain what it means: - A long tap on a data filter is partially implemented.
No animations when toggling series on bar and area chart types

1. The labels on the date axes are translucent when there is no transition.
2. The charts are not responsive. They are just scaled, the proportions of the elements stays the same regardless. It makes the absolute button size depend on the screen width and causes very big buttons on some screen sizes.
3. The tooltip points on line charts have wrong positions.

No bonus tasks. Not an issue, if not planned.

Doesn't deserve so many dislikes. No dislike from me.
