It's responsive - on width less than 400px the dates go under the title.

The minimap sliders don't move when you grad them and move the mouse cursor outside the chart

Telegram admins, where is my charts? I sent the archive yesterday, the bot accepted and said "Perfect! Would you like to add an URL to your app? Totally OK if not"

I do not see it in the list, what's the problem?

No "all" raw in informer
Yuriy Reznik Apr 17, 2019 at 14:01
in pie informer should contains average value, not sum

incorrect Y scale calculation
Pie chart timeline (navigator) has more than 7 days.
Chrome 73
The navigation at the end of the pie chart timeline (navigator) has glitches and sometimes wrong dates are displayed in the dates title.
Chrome 73
Small issue. The initially selected dates are different than 6 Mar - 6 April (the final month) and the first date in the range is half-off screen sometimes, but always off the size of the preview container.
Chrome 73
bad scale

- huge perfomace issues on every chart even on latest devices

- no percents column in tooltip of percents chart

- hard to call zoom-in: tooltip running away from mouse

- page zooming allowed on mobiles

- x and y labels flicker when slowly resizing chart

- problems with x-axis after zooming-out a "Eaten fruits" chart, see screenshot

> hard to call zoom-in: tooltip running away from mouse 

On desktop you may just click on the chart to see the details, no need to click on tooltip.

laggy bar chart scaling in Firefox mobile
Unable to select time range by dragging in the preview area (outside of the current window).

Two visual bugs on the photo. Tooltip is out of main area. Last column is empty.
There is no snapping to days, months
Eager Boar Apr 19, 2019 at 07:07
Not bugs:
* Free space to the right is made for purpose - to show that there is nothing more to the right.
* I don't see any reason not to show a tooltip if a bar doesn't fully fit the chart area.

Can't reproduce
Slim Jaguar Apr 19, 2019 at 10:44
(Screenshot) This happens after double click on tooltip.
I found minimal range too small, it's not draggable.
Header range text appears behind another text, and then moves to its place
