— Overall poor performance.
— The design does not comply with the guidelines.
— Y-scale always starts from zero.
— Dates are overlapped.
— The app is slow when filtering, scrolling and scailing all the graphs.
— The graphs take the entire width of the page when viewed from desktop browsers.

I have no time to meet design guides (

so many date labels

Earnest Falcon Apr 17, 2019 at 15:59

Unfortunately, I have fixed this issue after result submission. This is because count of labels depends of count of points in x axis(in fixed version this calculates by count of labels with max width)

No bonus tasks for any chart. Not an issue, if not planned.

Chart #2: The Y-scale on line graphs should start with the lowest visible value.
Float value showed for Y labels (see screenshot)

That’s right. Float value issue fixed next day after result submission 🤷🏿‍♂️

Hm... looks confusing on mobiles

Sorry. Initially, I tested on desktop, and I have little experience to develop for mobiles.

The 'views' button is displayed for single column chart. But that is a very small issue, should probably be ignored.

Sorry you didn't have enough time to finish with the design, but I appreciate your efforts. No dislike from me.

Thanks. It’s very interesting contest task. I’ll continue work on it in future, when I will get free time to do performance experiments, and I’ll fix all these issues.
