Thanks for review. We are waiting it.
Great competition, but more hard then first. It is great challenge for developers.

Btw, can not repeat distorted graph how on your screen
Unable to select pie chart segments

Yes, I added it new version http://logic.cool/telegram2/index.html
Long touch / long click functionality has not been implemented

(I could see it working in the updated version at public link provided in one of the previous replies.)

Not a bad work at all! Absolutely insane to give such a decent work a dislike. Why so many? No dislike from me for sure!

Long click added to new version http://logic.cool/telegram2/index.html

I do not understand who marked dislikes too. I think, bot system works well :)

Thanks for review. Good luck!

Administrators Telegram, where's my graphics? Yesterday I sent a zip archive, but I do not see my work in the list
Dreamy Frog Apr 17, 2019 at 15:22
Sorry, I am not admin of Telegram
Displayed graph window does not map in 1:1 to what's actually on graph.
Dreamy Frog Apr 17, 2019 at 15:27
It is not bug, I show over from this range. Real range is on attached image. Try to max scale and you can see it too
Amount of that "overlook" graph has changes with graphing range as well.
Dreamy Frog Apr 17, 2019 at 15:31
How I wrote above it is not bug. You see real range with left and right padding, no more
strange yaxes animation, long tap not supported
Dreamy Frog Apr 17, 2019 at 21:46
Yes, Y-axis rescale with delay, after mouse/touch end (I try minimizing calc). Long tab I added in new version (I need one day more) http://logic.cool/telegram2/index.html

1. The date range and the tooltip texts are not animated.
2. The tooltip design doesn't follow the specification and looks untidy.
3. There are excess lines on the bar chart during a line on/off transition.

1. Yes, I know. It is not main request in specification.

2. I like it :) I think tooltip more informative with zoom button like zoom out. About your video: I recalc position and move tooltip to more space by mouse/touch (how you show on center chart). Try it on iPhone5.

3. Yes, I fixed it in new version http://logic.cool/telegram2/index.html

Thanks for your comments.
Unable to select time range by dragging in the preview area (outside of the current window).

Sorry, can you record video, what do you mean, what device? What os?
In zoomed-in mode, there's no snapping to day boundaries. Video provided by Telegram clearly showed that snapping.
Dreamy Frog Apr 18, 2019 at 17:05
Telegram show snapping only at last chart. You can check it on my last #5 chart. Other zoom charts, you can change range at any positions
When selecting/deselecting series on area, bar and pie charts there's unnecessary fade to white transition, which produces flashing effect. Also in bar chart there's vertical lines because of that.
Dreamy Frog Apr 18, 2019 at 17:07
There's small jiggle of the grid lines while moving the current time range. Look closely at the top grid labels (78.4K, 3.8K) in the attached video: the actual maximum doesn't change, but they move up and down a bit.
Dreamy Frog Apr 18, 2019 at 17:19
I think you find range where Y changed in round scale, 78445 and 78412 will be 78.4k. You see same result but Y was changed. I think it is normal. 

Thanks for your comments
Values are not displayed in tooltip for stacked percentage chart

Yes, it is my decision. There we have data with 5 minutes interval, It is interesting to see. Thanks
