– Delay and jittering graphs on launch.
– The app doesn't fully comply with the guidelines.
– Overall speed is slightly below average.
– The third graph jitters and blinks when filtering.

Thanks for review!

It seems that I am alone use design specification and it turned out to be a useless task :(
Lagging on startup. Overall speed is slower than expected. I didn't like the black labels on the pie chart in day mode. Graph #5 is slow when filtering.

Thanks a lot.

See it now, it's a problem with initialization on some old devices. Suddenly found it late. I just start animation all charts in one moment, it was a bad idea.

Yes, I have't time to finish pie chart :(
When disable line, then scrrolls, then enable, lines is in incorrect position. Also Y-axis values have to many zeros

Oh, in this type of chart, I accidentally change state only for visible. It easy to fix but to late =(
I could not decide to use in this chart the removal of zeros or not. But in the next chart u can see removing.

1. Some x axis labels are drawn semi-transparent when chart is not being zoomed.
2. Look at the first label on this video. It changes randomly.
3. Top right label animation is restarted on each value change and blinking because of that

1) It can be semi-transparent because mockups show perfect actions of user.
2-3) It's a common bug, i have a bug in start and end indexes. In first stage we had a clipped graph. Just forgot to change one method :(

Thanks. Actually it's because I forgot to delete unchecked values, I made this pie chart in the last 30 minutes. :(
Long tap on buttons don't works,
Fit Rhino Apr 17, 2019 at 13:59
Yes, just forgot about it.
Good consistent app with all bonuses and attention to details and nice animations. Like it
The only issue is that pie slice value cannot be chosen.

No animation of texts inside selection box.
Fit Rhino Apr 20, 2019 at 19:33
Yep, too small time for all feature... but it easy to implement.
Nastya Lisovskaya Apr 19, 2019 at 20:39
Selection range not changing on zoom (must show the selected day)
Fit Rhino Apr 20, 2019 at 19:54
Thanks. Yes, I agree.

Chart in navigator is drawn outside the frame during animation
Fit Rhino Apr 20, 2019 at 19:31
Yep, after first stage i change design, and forgot to use clip.
Nastya Lisovskaya Apr 19, 2019 at 20:43
Colors in navigator are smooth - not by design.
Fit Rhino Apr 20, 2019 at 19:56
I didn't notice it in the design before
Nastya Lisovskaya Apr 19, 2019 at 20:46
First x label is changes randomly here too.

2. About smooth colors said before.

It's a strange, maybe because I mix color chart with background color instead alpha.
Incorrect text colors in a tooltip (22 dec is green in chart but blue in tooltip); If you're changing provided color, please change it everywhere :)

My bad, so many colors in specifications, miss this)
Despite performance on older devices, we can appreciate attention to detail in terms of static design and animations.

P.S. I had to take a vacation for the contest to make it better)
