— Overall performance is very poor.

— The third graph type is incorrect.
— Sloppy vertical scrolling.
— The app is very slow when scaling, scrolling and filtering.
— Low-quality graphs.
— The app is not optimized for small screens (iPhone 5S)

Upd. Glad to see that you've fixed the third graph!

Completely wrong implementation of the stacked bar chart (lines are used instead of stacked bars)

You sure, and I am also detected this issue, but ZIP was already uploaded. Any way it was fixed in 1 minute after ZIP was uploaded. Link to my github: https://euroflock.github.io/tgcc2/
It's possible to get graph without a... graph.

Sure, i am forgot to add one code string because don't have retina device for testing. Sorry
Graph resolution is obviously too low.
There's also some "breathing" (due to that?) during panning.

Something is wrong with performance/touch input processing is zoom-in mode.

Sorry but that is expected because animation for shifting in Zoomed mode is between days, not between pixels

Administrators Telegram, where's my graphics? Yesterday I sent a zip archive, but I do not see my work in the list

Sorry, but I am not TG admin)

Authors, please move my app's data one dir down. Nobody can view my app since it placed not at '/entry211/' and at '/entry211/build/'
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Is this my issue? So sorry)

Zoom makes chart blinking if selected range is long
Chome latest. Win10

Why you don't show some video for this issue? It is important for me to exactly understand what you mean. But anycase sorry if you feel not very good while you test my results)
Gentle Squid Apr 18, 2019 at 15:02
When zoom is in progress, it shows hourly values only for the selected day, not for the whole week, how it is shown in task video.

to me, this is ok from user experience perspective BUT:

when you zoomed in, and then made the selection to one week and then zoom back, it looks weird, because it tries to place the whole week to one point of main chart.
Groovy Hedgehog Apr 18, 2019 at 15:11
The same - better to attach a piece of video for proof. I think that zoom from one point (day) to the one day of the week - it is exactly what expected by designs. Sorry if it my mistake)
Gentle Squid Apr 18, 2019 at 15:04
Sometimes it crashes. I didn't find a solid way to reproduce it, but fast clicking the chart, tooltip and zoom out button does the trick
Chrome latest, Win10
Groovy Hedgehog Apr 18, 2019 at 16:04
I think in that testing way any app can sometime be tricked like you show) Please concentrate on the app result and functionality, look on the animate transition and relaaax.. no need to fast clicking on the chart for find the bugs, we are the humans. Ok, let me test you results ;)

"Ideally, the ratio of concepts - fucking did not do it myself, but I will shit other works with shit"
- relax man.:)

"Dear, tell me, how do you have the right to examine other people's results when you yourself have fully failed?"
- everybody has a right to examine other works.


regarding my work. I already provided a message that tells about the issues you listed.

all in all, let's be honest. what you have is:
- rendering of 5 charts, which takes maximum 1 day if participated in the first stage
- tooltips with ugly animations, some redesing, 2 times bolder lines in charts - that takes something like 4 hours
- and of course, the zoom logic of line charts, that is the only challenge in the contest... and it is a bit crappy :)))))
Gentle Squid Apr 18, 2019 at 17:29
you wanted a video for blinking - here you are :)))
Chrome latest, Win10
Gentle Squid Apr 18, 2019 at 17:32
the screen recorder doesn't catch all the frames, but you can see the blink on the 20th second. but it blinks all the time when I use your app
Wrong type of timeline (navigator) for pie chart. No pie chart sectors separation on hover / touch / click. The tooltips for pie chart sectors appear only on touch / click on percentage label, but not on the sector itself.
Chrome 73
Three first and three last dates of the stacked percentage chart have broken functionality for creating pie chart.
Chrome 73
The views button is displayed for single column chart.

In general not a bad work. No reason to put so many dislikes here. No dislike from me.
