— The app is not optimized for mobile devices.
— Design does not comply with the guidelines.
— The graphs are slow when scaling and scrolling, also jitter.
— The screen blinks and the graphs #3 and #5 jitter when filtering.

Weird. It was tested on iPhone 5S and it's completely okay.
> Design does not comply with the guidelines.
Where?

It's okay for me. But seems like Safari bugs.
> The screen blinks and the graphs #3 and #5 jitter when filtering.
Again, seems like Safari bugs.

UPD: have you noticed the glitch on the second chart?

A small issue is that the text in switched off buttons is not centered.

Overall I don't agree that this work deserves so many down-votes. No dislike from me.

Nice performance. Don't understand why is so many downvotes. Good job.

Looks like overflow. Minor, but valid issue.

Only safari. The y_scaled chart doesn't render the second polyline.

Looks like browser bug.

- there are no long tap;
- very often buttons not works on the first pressing
- when the size of bottom selector increasing fast, then dates on the X axis drawing only on the left or right (see screenshot)
