Issues

— Overall performance is poor to average.
— The first graph is broken when viewed on Android (lines are not displayed, checked on Samsung Galaxy J7 and S9).
— Some issues when scrolling and scaling (the attached video).
— The graphs also blink with black on launch. The third graph blinks when filtering.
— Vertical scrolling doesn't work unless you aim outside the graphs.
— Total is missing for graph #3.

Thank you.
1) The performance might seem less because there is an animation on regular scrolling. This is the reason why it is a bit “delayed”. I was originally intended it, but I’m still not sure if it is a good idea...
2) That might be true. I didn’t have Adroid devices to test the app properly. I’m not 100% sure, but most likely it’s WebGL related.
3) The attached video looks nice to me except for overlay blink. That’s a bug, indeed.
4) This is not a case on my device. However the bug is easy to fix.
5) I’ve done this on purpose. In my opinion, you shouldn’t accidentally scroll selecting the graph. I don’t think placing all charts on the one page was a good idea in the first place, but it was a contest criteria.
6) I’ve already answered this issue below.

By the way, there is a readme file. It’s not directly accessible because of the contest plaform, but it’s available via the link: https://jschart.usercontent.dev/entry120/README.md

You are right, I didn’t notice that the design had been changed since the first stage.

Do you mean margins? I did them smaller to make it fit nice on a small screen.

Y scale calculated not correctly

Does it have to be the local minimum, not the graph minimum?

No bonus functionality

Had no time, unfortunately... Anyway, it is not necessary.

Administrators Telegram, where's my graphics? Yesterday I sent a zip archive, but I do not see my work in the list
Some strange issue with one of the bars of the single column chart - it is not visible at all though the value displayed is more than 11 million

I don't think this work deserves so many dislikes. The author has put a lot of efforts, but didn't have enough time. No dislike from me.

Thanks for your feedback. You wrote the most helpful review so far, although I had known about this problem. It is a quite annoying bug which was fixed right after the release with literally one line of code(https://github.com/Azarattum/ChartsApp/commit/dd452ab4e501aadf6b0b89fbe83e5695b3e45166). Unfortunately, I just didn’t notice the issue before the deadline because of lack of time.

About ratings, they are understandably unfair. Just because people see that I forgot about the selector style, but I bet nobody have noticed that render was done with WebGL(took the most of project time).
Nobody added any issues yet...
