— The graphs jitter on launch.
— The second and the third graphs are slow when filtering.
— Bonus goal is partially implemented (+), however graphs #1-#3 are slow when filtering and scaling while zoom is applied.

– Graphs jitter on launch.
– The app crashes after zooming 6.04.2019 on the third chart.
– Filtering the third graph is glitchy (the first video). It is also slow on the last graph.
– Dates performance could be better (the second video).
– Bonus goal is partially implemented (without the pie chart). Zooming in is slow on the graphs #1-#3.

Thanks for feedback!
There is 150ms delay before animation start. It is not glitch, in my opinion.

Sure, there may be a bug, but I can't reproduce it on emulator :(
Bonus part takes me down...

There are visible white lines between the Apples and Oranges areas in graph #5. Filtering graph #5 when maxed out is slow (low fps). Graphs of their parts can disappear when switching day/night mode.

This is for separate animation for each date component.

It's not clear for me how to animate two lines on the same chart to keep grid lines precision.
The app interacts with user / starts every animation with noticeable delay (I suppose that it's because of background rendering/model rebuild, but not sure). Not sure video reflects it, but when you use the app, you feel it.
AND because it uses background thread, and posted invalidate events from it only when model is ready to draw, I can't prove the bad perf & not smooth animations by screenshot with bars, but again it noticeable when you use it.

Yes, there is 150ms delay, but not due to model calculation. This is my decision for UX (not the best, I suppose).
Invalidates are not posted from background thread, actually. Visually I can't notice any slow frames in provided videos.
