Issues

– The app is slow when filtering graphs with big data (#3 and #5)
– Scrolling and scaling of the graphs are laggy.
– Switching themes causes the screen to blink.
– Y-scale isn't relative.

Thanks! I agree with all of the issues above. I didn't participate in the stage 1, so it's completely my fault that I didn't have enough time
Too slow when filtering graphs #3 and #5.

Agree, scrollview interferes with touches there. I added some minimal dragging offset, but I probably had to increase it a bit more

Performance issues on 3rd and 5th charts while scrolling and scaling. Screenshots with GPU profiling are attached.

Thanks for profiling it! Honestly I didn't profile it myself, just tested on the lower-end device to make sure it's smooth (Lenovo A800, Android 4.0.4)

When the chart is scrolled to the very end, its right edge is expected to be fixed. Actually, it is not.

Popup has gone off screen

Yeah, I definitely had to do some more testing on smaller screens (<4 in). Thanks

Overview's border glitches on theme switch

Interesting, what device is that? Doesn't happen in emulators/multiple devices I tested on
Semitransparent values on x axis (video above)
Keen Croc Apr 18, 2019 at 11:31
That's exactly how it works in the 1st contest winner app. Did you test it?

Blocked while installation
Keen Croc Apr 18, 2019 at 12:43
That's the Play Store issue, obviously if you're installing apps from 3rd party developers it's going to complain :)

Weird scroll lines (they should be much thinner)
Keen Croc Apr 19, 2019 at 09:47
What do you mean by "scroll lines"? If you're talking about horizontal lines, they physically can't be thinner than 1 px
Dreamy Penguin Apr 18, 2019 at 12:18
Scroller has weird line (does not match designs)
Dreamy Penguin Apr 18, 2019 at 12:20
Time axis has too many marks after touch end - does not match design
Keen Croc Apr 18, 2019 at 12:30
It matches the design perfectly, unless you take a screenshot midway through the scroll (exactly like in the demo)
Dreamy Penguin Apr 18, 2019 at 12:21
Percent popup left values are not aligned right
Keen Croc Apr 18, 2019 at 12:45
I see you have some great attention to detail ;)
Dreamy Penguin Apr 18, 2019 at 12:24
First time axis value is cut
Keen Croc Apr 18, 2019 at 12:28
Of course, since you dragged it to the left. Test the winner of the 1st stage app
Dreamy Penguin Apr 18, 2019 at 12:28
Pointer disappears on end touching
Keen Croc Apr 18, 2019 at 12:45
I didn't finish the main goal (switching to a daily view), so there's no need for it to stay
Dreamy Penguin Apr 19, 2019 at 06:47
By scroll lines I mean lines at overview, birdview, scroller, bottom chart. They have 1dp at design specs. And chart lines have 2dp - as implemented
Keen Croc Apr 19, 2019 at 09:47
(Same issue reported twice) No they're exactly 1px actually
Nobody added any issues yet...
