Slow. Y-scales always start from zero. Part of the expected animations are missing.

Two axis chart is not implemented. Bar chart doesn't work.

No tooltip on any chart
Long tap on filter button not implemented

Double axis chart has only 1 uncolored axis

First 2 charts start from zero instead of local min

Having stacked bar on the screen decreases table view performance. Not really visible on the video though.

— Upper bound values are cut when scaling (the attached video #1). 
— The app is slow and shows incorrect Pears value when scaling the third chart.
— Not possible to view the box with the details about points on the graphs.   
— Values on the Y-scale are cut (the attached screenshot #2).

Trimmer can go out of bounds? always trims on different date (left bound).

None of the charts is fully visible

Crashes on iPhone 5

Rapidly switching theme makes the UI elements blink

Y values are cut-off

Does not support iOS 8. Telegram does.

Major issue: line joints change during movement

Major issue: Minimum value is always 0. Not only the UX is suffering, but also it gives this contestant a major advantage in performance over other participants.

Critical issue: 17 fps during bar chart scaling on iPhone 6+. For more details read my comments about performance of entry213.
