— Overall average speed.

— Y-scale starts from zero (graph #1, zoomed graph #4).
— The app is slow when scaling, scrolling and filtering the third and the fifth graphs.
— Long tap on a data filter doesn't work.
— Filtered values are visible on data points info.
— Bonus goal is implemented, however parts of expected animations are missing.

Thanks for the review.
I thought that y-scaled should start from zero only for y-scaled graphs, my mistake.
Long tap on data filter works for me on touch devices.
Y starts from 0 (The Y-scale on line graphs should start with the lowest visible value)

Y-scaled grpah starts at lowest visible value, others not. What's wrong?
zoomIn and zoomOut refresh the selected filters

Yes, I can add saving state of filters in next version :)

- perfomance issues on any action and any chart

- design not like in mokups

- no percents column in tooltip of percents chart

- zooming-in without internet breaks the chart

- page zooming allowed on mobiles

- no animations on value change in interval or tooltip

- title and interval are not on the same line and not sometimes interval is too long, transfers below title and cause page jiggling, see screenshot

Technically fading x values are totally correct, but aesthetically it's better to fade them depending on time rather than only scale

Y starts from 0 (The Y-scale on line graphs should start with the lowest visible value) (c) on the 4th graph
Neat Deer Apr 17, 2019 at 12:30
4th graph is not y-scaled, why it should start with the lowest visible value?
I don't know how I reproduced the value that was able to select zero day (only once when I screenshoted), but also the values in the circle are not well rounded (in sum there are not 100%), repeats
Neat Deer Apr 17, 2019 at 12:41
Seems it's bug. I should have more carefully rounded the values.
The canvas with point crops it
Neat Deer Apr 17, 2019 at 12:35
There is not this situation on screenshots of contest. I think it's normal.
> 4th graph is not y-scaled, why it should start with the lowest visible value?
I thought it should. Nevermind, JFYI I haven't done changing Y from 0 at all due to lack of time) and your graphs look really great, nice job

Thanks! :)

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?.
Neat Deer Apr 17, 2019 at 15:28
May be this because you didn't enter url...
> I don't know how I reproduced the value that was able to select zero day (only once when I screenshoted)
I was able to reproduce it with a resing browser that leads to changing X position for the 5th graph (offsetX should change as I got). After that resing in mode with circle leads to the issue on the screenshot. All other graphs don't have the behavior. In the first attempt I didn't resize browser but looks like I switched between mobile and desktop version so the position was changed and I saw the issue

Thanks for the details

Some problem with scale of charts. Check points at screen, they are oval
iOS, Safari, iPhone6
Long touch event works only on touch devices.
Chrome 73, Desktop
Tooltip in the preview area appears only on click. It doesn't appear on mousemove or touchmove
Chrome 73
Initially selected date range for all chart is almost 2.5 months at the beginning of the year, unlike the suggested by contest screenshots final month
Chrome 73
Dreamy Frog Apr 18, 2019 at 17:51
Pie chart in zoomed mode has other number result with normal mode. Select first day on chart and check result in zoomed mode, they are different.

Very hard to select day what I want. I need to click on right place (I try select first day). Will be great if you use mouse move event.

If I click on chart, I zoomed, if invisible result form under my click. I think you should stop event for show and then click on result form.

Btw good work, good luck

Two visual bugs on photo.
No snapping to days, months

Y doesn’t start at lower visible value
Small issue with timeline (navigator) being displayed for the single column chart in zoommed mode.
Chrome 73
The lines at lowest values are almost hidden.
Probably could be ignored as a insignificant issue.
Chrome 73
The date range does not always fit, sometimes the tooltip shows strange values

The left edge of the stacked bar chart is drawn incorrectly (looks like it's stick to the left edge). Also the left date label just appears/disappears on scroll.
