— Overall performance is below average.
— The design does not fully comply with the guidelines.
— We also noticed a delay on launch.
— The graphs blink on vertical scrolling.
— The app is slow when scaling all the graphs and filtering graphs #3 and #5.

Thank you, looks like a valid bug, I guess there is one animation frame missing in some cases

Administrators Telegram, where my graphics? Yesterday I sent a zip archive, but I do not see my work in the list

Hello, I'm really sorry for that
- There is a strange red border around a button after click
- The disabled buttons labels are not centered
- The tooltips have a wrong font (a serif instead of a sans serif)
- The tooltips texts are not animated

Thank you. I believe buttons visualization can be improved a bit.
Regarding wrong font - it was my intentional choice to use monospaced font for labels to reduce date width trembling.
The only small issue I could find is that the text of switched-off button is not centered.

Even though there are no bonus tasks, the work is really decent and mostly follows the design guidelines.

It even has documentation! Awesome.

I disagree that this work received so many dislikes.
