Long press on button doesn't working

Bad design, long tap not works, line charts Y-axis begins from 0, filter has clipping issues by corners, Y-axis has no animation

1. Chart design seems too rough and raw with solid color and transparency (minor issues).
2. Performance is very bad (especially on stack bar when fully shown and scrolled) (though auto height wrap logic is correct, what I can't say about many other applicant's apps)
3. Edges are always cut at any scale
4. Date info dialog does not support hoover gestures (only separate clicks) (in video telegram provided this feature is shown). I want to admit nice data zoom in animation, though again performance suffers a lot. Also it seems that after zooming in data is not correct in some charts.
5. Pie chart zoom in switch animation coordinates somehow work not as intended.
6. No long tap (mentioned before)
7. Stack bar chart zoom in animation is totally broken and represent data in random stack order for each bar
8. Strange behavior of control area at edges.
9. No line appear/disappear animations. No bottom line date change animation. No stack bar filtering change animation.

Double tap is not working on 'view' diagram. I expected it leads to zoom in zoom out

Recreate activity while changing theme

Weird behavior of chart scrollbar

Poor perfomance in general

Broken animation of pie in case when selection button clicked during animation

— The design does not comply with the guidelines.
— The app is sloppy on vertical scrolling.
— Animations are missing on filtering.
— Bonus goal is partially implemented (+), however the overall performance is low, pie chart is cut.

Incorrect design and low performance overall.
