Thank you for recording a video, it helps, since it's hard to reproduce. Labels pool optimization just needs a fix for one edge case.

Thanks for the exact steps and a video recording. You have good testing skills. Definitely a reminder for me to disable user interaction during animations/transitions when it's not intended.

Yeah, the reason is the same as for the first crash :) User interaction was not intended during zoom transition animation. Easy fix though.

Thank you for reporting and recording a video! My bad I didn't had a chance to test it on iOS 8.

Yeah, thanks again for the video. I should have been tested it on iOS 8. Assuming integer overflows.

That's correct, I left it in minor list, didn't have time to come back to it.
Nevertheless, it was easy to support. Check it out on attached video.

Thanks again! It was all caused by one issue which I fixed already, video without issues was already posted to the very first comment. See attached zoom/in out video without circle points issues.

Right, it was posted 3 times here already. Fixed that already, forgot to disable line indicators for bar and area charts in one place.
Thanks for reporting though!

I agree, thanks for pointing out, didn't have a time to polish all the gesture recognizers UX.

Yes, it's a known issue, animation just does not start from where it ended and it looks like a frame drop if filtering fast. Easy fix though.

Thank you for testing, Sergey!

> A little bit strange animation, when zooming in to dates in the end, but it's not bad at all.
I consider it bad :) Broke it during last hours, one liner fix to remove debug reset of animation point to zero.
Please see intended animation attached.

> Zoom out button overlaps header.
Right, it's a known issue for 5S screen width, just didn't have a time to fix it. Fix ETA is 30 minutes.

> View with values has black artifacts during resize animation.
Good catch, I was playing around with a blurred background and forgot to clean it up completely, so it's causing that artifact. Fixed in one line.
Check out blurred one too though on attached screenshot :)

Thank you for sending the video recording!
Visibility states just need a small fix.

Thank you for the feedback!
It's related to the first comment from Sergey:

Good catch btw.

It's a feature ;) I'm hiding days intentionally for more than 4 months range.

Yep, same cause as for your previous bug. Was already fixed easily with one line.

It's a feature ;)

Minor updates otherwise causing "flashing" of values, which was reported for me as a bug in stage 1.

I set a threshold to animate only in case of "significant" range updates

It's a feature ;)

Already replied in another issue.

Imagine all the months with the same date:
Mar 21 Apr 21 May 21 June 21
I just avoided that.

> advantage in performance over other participants

I don't have performance bottlenecks in date formatting. If you are developing for iOS - DateFormatter can be cached to achieve top performance, since creating it's instance is the bottleneck itself.

There is alsmost no-to-very-minor overhead between displaying "month only" vs "month + day".

Looks not too bad :)
Thanks for sending a video. Unfortunately, it's not noticeable on mp4, but I got the point.

Can be optimized though! ;)

Unfortunately, I didn't get which artifacts you meant.
I guess you meant position indicator labels, but not sure.

All right. Same cause as about 5 other issues reported here. Already fixed in a one line.
