Overall performance is slightly below average.

— The graphs slightly jumps on launch.
— Sloppy on vertical scrolling.
— The app is slow and laggy when scrolling and scaling the third graph.
— Filtering the third and the fifth graphs leads to jittering.
— Bonus goal is not implemented.

Telegram admins, where is my charts? I sent the archive yesterday, the bot accepted and said "Perfect! Would you like to add an URL to your app? Totally OK if not."

I do not see it in the list, what's the problem?.
A lot of critical issues.

1. Sometimes the chart jumps by itself if u just scroll.

2. Incorrectly drawn data, bar chart does not look as it should be.

3. 5th chart very laggy (~2-3 fps).

Look at the video.

1. It's called an animation. Range had changed, so did charts.

2. Not sure, what is about.
In some places graph jumps abruptly
No snapping to days, months
Wrong scale

By design. I prefer to show somewhat 'nicely' labels.
The long touch / long click functionality has not been implemented. Mouse clicks don't seem to be working on buttons.

Thanks for the efforts, most of the design guidelines are met, no dislike from me.

It's implemented really. The behavior you got - it's because of switching from desktop to mobile emulation without refreshing page.
1. The bars chart minimaps are drown outside their areas during a transition.
2. The lines chart leaves traces on the minimap after a enabling/disabling a line.
3. There is no date range label.
