— Sloppy vertical scrolling.
— Total values are missing. (graph #3)
— The third graph and the fifth graphs are slightly slow when filtering.
— Bonus goal is not implemented.
— Dates are distorted on maximum scaling

Thank you for the feedback.

The row with total value is present on third graph, but it has white color in day mode just like in night mode, silly mistake.

Looks like I forgot handle fractional pixel ratios like 2.75 on Redmi Note 5, this is sad.
No header dates animation, the lines on the second chart just disappear instead of fading out, the date scale keeps translucent labels when there is no animation and uses a bad looking narrow font on a wide scale, the lines are too thick, the minimaps have excess side paddings.

Thank you for the feedback, some comments:

1. There is no animation in range header and tooltip because I think that it looks sloppy. Maybe I should have done animation for checkboxes, for them it looks appropriate.

2. There is no fading out for the second chart because in my app when y axis has nothing to show it just disappears without animation and the empty message is printed. Here is the same logic, because one axis has only one graph, but I agree that in this case it looks strange.

3. Yes, x axis has no animation, it's an intended behaviour. Font for x axis is really looks shitty, maybe I should reduce the ticks count for desktop too, like it's done for mobile version. Line thickness is reduced for mobile too.

4. Overview chart has paddings because I don't like how opaque grips overlay the data. I think that scroll bar window should correlate with the displayed data.
Authors, please move my app's data one dir down. Nobody can view my app since it placed not at '/entry211/' and at '/entry211/build/'

"We now expect a .ZIP file containing an index.html evoking all the dependent resources using relative addresses." - the requirement was clear, it's only your fault, stop spamming, please.
How long for you "containing " began to mean "containing at the top level."

Do you think that the organizers had to investigate every work to figure out how to host it? This is obvious that the process will be automated. I feel sorry for you, but spamming it's not the way out.

Do you mean left padding? If yes so I already answered to Giant Parrot about it, but if no could you please describe it better?
I think there shouldn't be any 'Views' button for the single column chart.

But the work looks nice in general. Mostly follows the design guidelines. Appreciate your work. No dislike from me.

Thank you for the feedback. I decided keep the button for consistency, in my app all graphs can be disabled with further empty message appearing.

I've noticed nasty gaps on the screenshot between columns, what pixel ratio (window.devicePixelRatio) your display has? Something fractional? Or just scaling?
Nobody added any issues yet...
