— Some glitches when scrolling the filtered graph (the attached video).
— The app is sloppy on vertical scrolling and filtering, also zooming in and out.
— Bonus goal is partially implemented (+), the pie chart is missing.

The app is very slow on Android 5.1.1. It's impossible to scale the 3rd chart.

Vertical scrolling is critically sloppy.

Redraws frames even if nothing happens (open gpu debug bars on device)

Chart navigation view design is not updated to the stage 2. No points "run" animation on selection change. It is shown on the demo gif. Also, no point card position animation.

1. App is crash when run from task manager.
2. Navigation design doesn't match the contest
3. No implementation of a long press on the filter
4. Can remove all filters
5. slow working
6. problem when scroll charts list
7. not all bonus tasks

1. Stage 1 chart preview view design (Small visual issues)
2. Broken line (see video)
3. Strange empty screen
4. Chart preview view do not wrap at the bottom edge
5. All Charts are clipped at any zoom
6. Cannot scroll whole view/screen touching big or small chart views (wrong or no touch event intercept handling)

7. Wrong appear/disappear animations
8. Line start absolute coordinates are somehow wrong.

11. Percent Chart Issues. Sometimes animation does not play (see video below).
12. No long press filtering (Apply to all charts) (see video below).
13 Neither bug nor bad UX, just date intersect appearance are wrong. Also, percent values are not correct (see screenshot).

9. Stack Bar Chart. Totally broken and laggy. I dont know if it is possible to recreate this by purpose )

10. Chart 4 Disappear somehow. Also I have catch app crash (hard to reproduce) when click on data filter to zoom in and fast after move slider.

14. Date info percentage dialog do not correspond to desing provided (percent, Name, value, (eg. 30% Apples 34050)). See screenshot above (11,12,13 issues section)
