— The graphs and the previews are blurry. The design does not comply with the guidelines.
— Graph #2 jitters when scrolling.
— The box with the details about selected points on the graphs is cut in some cases.
— The point is cut (the attached screenshot #1).
— The context menu appears while trying to long tap on iOS (the attached screenshot #2).

Just wondering, what exactly is wrong in the design?
Canvas on which graphs being drawn on clearly have resolution set way too low. Due to that there's visible artifacts on graph slopes.

Hm, just curious what could be the cause. Jumps too big to be a rounding issue.
Weird pixel between border and background of buttons (Screenshot)

yeah, CSS is not really my thing :-)
Doesn't work in Edge due to some javascript error. This issue could probably be ignored, because the Edge is going to switch to chromium engine soon and also js code could be processed with babel to be compatible with ES5/ES6.

Not a bad work at all, definitely doesn't deserve so many dislikes. No dislike from me.

Thanks for the feedback!
I did not care about IE/Edge compatibility since it was not defined in contest requirements. I bet babel will solve that.
- not the same animation of text change as in design
- strange values on the y axes
- no animation for table appear/disappear
- box for selecting visible part of plot is smaller than on design
- no animation for appear/disappear of values under the plot

1. agree
2. what's strange there?
3. what's table?
4. Do you mean slider? it's initial size, you can resize it as you wish. There is no default size specified in the designs.
5. X labels? Perhaps it's Opera related issue -- it works in Chrome.
No main view animations

What animations exactly do you miss?
Nobody added any issues yet...
