– Low speed overall.
– Inconsistent behavior when scaling the first graph (the attached video).
– Incorrect type of the third graph.
– The app is slow when filtering the last graph, scaling graphs #1 and #2.
– Bonus goal implemented, however the animations are slow, graphs #1 and #2 are slow when scrolling and scaling.
LG Nexus 5X, Android 8.1.0
Slow when filtering graph #5.
Samsung Galaxy S4, Android 5.0.1
A nice app, made according to the design guidelines, and with bonus task completed. However, lags when changing time range for the first graphs on Samsung S9 are critical.
Samsung Galaxy S9, Android 9
Stacking bar has wrong scale (49k total displayed as approx. 25k). Most charts are laggy even on a modern phone.

Broken animation in #3 chart

I defined incorrect chart type. Each next chart must starts from end of previous but on my presentation each starts from 0, and charts with maximum averagae values are on back, with minimum on front. As a consequence it seems that scale on Y-axis is wrong and some bars are not present
Weird enable/disable animation for stacked bar chart

Cannot install
Xiaomi MI A2 Lite
Incorrect data are displayed:
1. Missed apples (but present in tooltip)
2. Kiwi larger than Apricots in a tooltip, but smaller in a bar.
3. The same as 2 for lemons & oranges

Yes, these values start from null, for those selected day they less than values from charts with more lower averagae value, and overlapped by them
Artifact at range selector for #5 chart

I decided, that in design is error, date are presented on buttons, date in title is dublicate and furthermore we have three dates
Poor performance. Especially when enable/disable lines, and opening tooltip. ALSO noticed, that app redraw frame everytime even when NO INTERACTION from user performed.
Xiaomi A1 / Android 9
Cannot install app somehow

Vote up for the bonus part done, but the performance is very poor even for the first chart.
