– The design does not comply with the guidelines.
–  Very slow overall.
– The app doesn't have data filters.
– No data points info on tap (#2–#5 graphs).
– Y-scale isn't relative.

No data points info? Wait a minute, but what is at attached videos?

Y-scale not relative... Hmm... WTF... are you sure that you test my app? Because I spend a lot of time to make it relative in any case, and it almost perfect

Very slow? Strange impression... Only third chart slow because for some reason it has animations overlay, but all other charts smooth not slow, because user must see transitions of chart i other cases it will be too fast and for user it will be hard to understand what going on, maybe animations slower then tg contest examples, but as for me it's just pretty good, imho :)

No theme switching. No scrollers. No pointers. Does not match designs

No scrollers? App has scrollers but I dont't have time to implement it like shown at design, try to move small chart below a biggest one. Also why did you mean by pointers? Maybee sheet with data when you tap at diagram? If yes then it works by long click
1. No enable/disable buttons, so no able to test the app fully
2. weird text sizes/styles
3. weird tooltip window UI
4. Bad touch detector (doesn't catch clicks, long clicks, you only need to touch and scroll horizontally to get tooltip opened)
5. No date range view implemented
6. no night theme implemented

Incorrect design, part of the filters are missing, slow when scrolling.

Press long click to show sheet with data, then move finger to the right edge of display. Sheet data move out from the screen

Fast vertical scrolling between the charts leads to appear black screen on my phone. p.s. my phone has bad performance

Black screen appears not only at phones with bad perfomance. It's looks like it's a bug of android sdk. For some reasons recycler view don't like a textureview, and while scrolling it recreates textureview canvas and , and I don't find any solution that fix it. Maybee rewriting recyclerview can solve it...
UNUSABLE performance: app performs some rendering in background, every animation has a noticeable delay & very loooong duration. Videos are attached.

delay and long duration? You can say this about third chart and it's will be true, but not about others. Or you think that if app show you data range immediately it will be much more better? Animation durations and delays same to winner app of first stage. And after watching of this videos I can't understand what wrong with animations, but maybe I'm blind...
Nobody added any issues yet...
