— Overall performance is average.

— Y-scale starts from zero (graphs #1 and #2).
— The app doesn't fully comply with the design guidelines.
— The app is slightly slow when scrolling the graphs. It's also slow when filtering and scrolling the third graph.
— 'Total' values are missing (graph #3).

Not bad, but 0 Y-scale and design (scrollbar sides) are disappointing.

bad scale

No button long click handling (but the long tap handling works)

can not select value out of range

The lowest value on the chart is not pushed to the bottom as it was required in the task

text label not centered

The off button text is not centered

- no smooth animation between values
- no text animation
- no "All" in plot #3
- in plot #5 percentage and labels has incorrect positions
- in date range month has not full name

The lines are too thin on large scale and too thick on small scale for line graphs in Edge. Probably could be ignored, because the Edge is going to switch to chromium engine soon.

I especially like the drag functionality of the main preview of the chart - cool idea.

Overall the work mostly follows the design guidelines. It's unfair it has received so many dislikes.
