Yes, I did not have time for these animations.
Why do you think y axis values is strange?
Jumping on timeline it is a little bug on “views”, i fixed it in 5minutes after contest deadline ended.
Thank you.

There are glitches on bar charts, perhaps because of decimal bar widths

There is no fading in/out animation when y values changing

It is too hard to open zoomed chart using mobile phone

But, cool work anyway!

I’ve implemented only half of zoom-in-out functionality (no transitions, no hours timeline, but the data is displayed correctly and checkboxes are working) and decided to hide the arrow at last moment. You only one who noticed it, thank you!

True, I didn’t do that

No long touch / long click functionality has been implemented

But the work in general is not bad. No dislike from me.
