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.

Charts jump when scrolling horizontally.

No animations when scrolling fast

Can't enable/disable columns

After check and uncheck bars chart some artifacts keep on screen.

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.

In some places graph jumps abruptly
No snapping to days, months

Wrong scale

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.

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.
